Using a temporal bisection task, participants classified seconds-long videos of naturalistic scenes as short or long (duration), or slow or fast (passage of time). Videos contained a varying number and type of events. We found that a large number of events lengthened subjective duration and accelerated the felt passage of time. Surprisingly, participants were also faster at estimating their felt passage of time compared to duration. The perception of duration scaled with duration and event density, whereas the felt passage of time scaled with the rate of change. Altogether, our results suggest that distinct mechanisms underlie these two experiential times.}, doi = {https://doi.org/10.1016/j.concog.2024.103635}, keywords = {Passage of time, Judgment, Time perception, Event cognition, Virtual environment}, url = {https://www.sciencedirect.com/science/article/pii/S1053810024000023}, } @Article{new2024unipseudo, author = {New, Boris and Bourgin, Jessica and Barra, Julien and Pallier, Christophe}, title = {UniPseudo: A universal pseudoword generator}, journal = {Quarterly Journal of Experimental Psychology}, year = {2024}, volume = {77}, number = {2}, pages = {278--286}, pdf = {http://www.unicog.org/publications/New et al. - 2023 - UniPseudo A universal pseudoword generator.pdf}, publisher = {SAGE Publications Sage UK: London, England}, url = {htthttps://journals.sagepub.com/doi/abs/10.1177/17470218231164373}, } @PhdThesis{, author = {Lucas Benjamin}, title = {Human sensitivity to statistical regularities at different scales in auditory sequences: evidence from electrophysiology and behavior in adults and neonates}, school = {Sorbonne University}, year = {2023}, pdf = {http://www.unicog.org/publications/Manuscript_Vf_Corrected.pdf}, } @PhdThesis{, author = {Cédric Foucault}, title = {Adaptive learning in humans, brains, and neural networks: The role of uncertainty and probabilities}, school = {Sorbonne}, year = {2023}, } @PhdThesis{, author = {Marie Guillemant}, title = {Développement d'un microscope à trois photon adapté à l'imagerie du primate non humain vigile}, school = {Université Paris-Saclay}, year = {2023}, } @PhdThesis{, author = {Harish Gunasekaran}, title = {Subjective recalibration and endogenous delta oscillations in humans}, school = {Université Paris-Saclay}, year = {2023}, } @PhdThesis{, author = {Marie Lubineau}, title = {Nouveaux outils pour le diagnostic de la dyslexie}, school = {Université Paris Cité}, year = {2023}, } @PhdThesis{, author = {Alexandre Pasquiou}, title = {Deciphering the Neural Bases of Language Comprehension Using Latent Linguistic Representations}, school = {Université Paris-Saclay}, year = {2023}, pdf = {http://www.unicog.org/publications/final.pdf}, } @Article{agrawal2023dissecting, author = {Agrawal, Aakash and Dehaene, Stanislas}, title = {Dissecting the neuronal mechanisms of invariant word recognition}, journal = {bioRxiv}, year = {2023}, pages = {2023--11}, publisher = {Cold Spring Harbor Laboratory}, url = {https://www.biorxiv.org/content/10.1101/2023.11.06.565812v1.abstract}, } @Article{al2023brain, author = {Al Roumi, Fosca and Planton, Samuel and Wang, Liping and Dehaene, Stanislas}, title = {Brain-imaging evidence for compression of binary sound sequences in human memory}, journal = {eLife}, year = {2023}, volume = {12}, pages = {e84376}, publisher = {eLife Sciences Publications Limited}, url = {https://elifesciences.org/articles/84376}, } @Article{amalric2023evaluating, author = {Amalric, Marie and Roveyaz, Pauline and Dehaene, Stanislas}, title = {Evaluating the impact of short educational videos on the cortical networks for mathematics}, journal = {Proceedings of the National Academy of Sciences}, year = {2023}, volume = {120}, number = {6}, pages = {e2213430120}, publisher = {National Acad Sciences}, url = {https://www.pnas.org/doi/abs/10.1073/pnas.2213430120}, } @Article{azizi2023spontaneous, author = {Azizi, Leila and Polti, Ignacio and van Wassenhove, Virginie}, title = {Spontaneous alpha brain dynamics track the episodic "when"}, journal = {Journal of Neuroscience}, year = {2023}, publisher = {Soc Neuroscience}, url = {https://www.jneurosci.org/content/early/2023/09/11/JNEUROSCI.0816-23.2023}, } @Article{benjamin2023humans, author = {Benjamin, Lucas and Fl{\'o}, Ana and Al Roumi, Fosca and Dehaene-Lambertz, Ghislaine}, title = {Humans parsimoniously represent auditory sequences by pruning and completing the underlying network structure}, journal = {Elife}, year = {2023}, volume = {12}, pages = {e86430}, doi = {https://doi.org/10.7554/eLife.86430}, publisher = {eLife Sciences Publications Limited}, url = {https://elifesciences.org/articles/86430}, } @Article{BOUNMY2023119849, author = {Tiffany Bounmy and Evelyn Eger and Florent Meyniel}, title = {A characterization of the neural representation of confidence during probabilistic learning}, journal = {NeuroImage}, year = {2023}, volume = {268}, pages = {119849}, issn = {1053-8119}, abstract = {Learning in a stochastic and changing environment is a difficult task. Models of learning typically postulate that observations that deviate from the learned predictions are surprising and used to update those predictions. Bayesian accounts further posit the existence of a confidence-weighting mechanism: learning should be modulated by the confidence level that accompanies those predictions. However, the neural bases of this confidence are much less known than the ones of surprise. Here, we used a dynamic probability learning task and high-field MRI to identify putative cortical regions involved in the representation of confidence about predictions during human learning. We devised a stringent test based on the conjunction of four criteria. We localized several regions in parietal and frontal cortices whose activity is sensitive to the confidence of an ideal observer, specifically so with respect to potential confounds (surprise and predictability), and in a way that is invariant to which item is predicted. We also tested for functionality in two ways. First, we localized regions whose activity patterns at the subject level showed an effect of both confidence and surprise in qualitative agreement with the confidence-weighting principle. Second, we found neural representations of ideal confidence that also accounted for subjective confidence. Taken together, those results identify a set of cortical regions potentially implicated in the confidence-weighting of learning.}, doi = {https://doi.org/10.1016/j.neuroimage.2022.119849}, keywords = {Confidence, Uncertainty, Probabilistic inference, Learning, Functional MRI}, url = {https://www.sciencedirect.com/science/article/pii/S1053811922009703}, } @Article{ciccione2022outlier, author = {Ciccione, Lorenzo and Dehaene, Guillaume and Dehaene, Stanislas}, title = {Outlier detection and rejection in scatterplots: Do outliers influence intuitive statistical judgments?}, journal = {Journal of Experimental Psychology: Human Perception and Performance}, year = {2023}, pdf = {http://www.unicog.org/publications/Ciccione_et_al_2022_Outlier_detection_rejection.pdf}, publisher = {American Psychological Association}, url = {https://psycnet.apa.org/doiLanding?doi=10.1037%2Fxhp0001065. }, } @Article{ciccione2023trend, author = {Ciccione, Lorenzo and Sabl{\'e}-Meyer, Mathias and Boissin, Esther and Josserand, Mathilde and Potier-Watkins, Cassandra and Caparos, Serge and Dehaene, Stanislas}, title = {Trend judgment as a perceptual building block of graphicacy and mathematics, across age, education, and culture}, journal = {Scientific Reports}, year = {2023}, volume = {13}, number = {1}, pages = {10266}, publisher = {Nature Publishing Group UK London}, } @Article{dehaene2023comment, author = {Dehaene-Lambertz, Ghislaine and Sprenger-Charolles, Liliane and Col{\'e}, Pascale and Casalis, S{\'e}verine and Dehaene, Stanislas and Bijeljac-Babic, Ranka}, title = {Comment faciliter l'acquisition du vocabulaire {\`a} l'{\'e}cole maternelle?}, year = {2023}, url = {https://www.reseau-canope.fr/fileadmin/user_upload/Projets/conseil_scientifique_education_nationale/Ressources_pedagogiques/CSEN_Synthese_acquisition_vocabulaire_maternelle_WEB.pdf}, } @Article{desbordes2023dimensionality, author = {Desbordes, Th{\'e}o and Lakretz, Yair and Chanoine, Val{\'e}rie and Oquab, Maxime and Badier, Jean-Michel and Tr{\'e}buchon, Agn{\`e}s and Carron, Romain and B{\'e}nar, Christian-G and Dehaene, Stanislas and King, Jean-R{\'e}mi}, title = {Dimensionality and ramping: Signatures of sentence integration in the dynamics of brains and deep language models}, journal = {Journal of Neuroscience}, year = {2023}, publisher = {Soc Neuroscience}, url = {https://www.jneurosci.org/content/43/29/5350.abstract}, } @Article{DWARAKANATH2023, author = {Abhilash Dwarakanath and Vishal Kapoor and Joachim Werner and Shervin Safavi and Leonid A.

How does ignition interact with intrinsic cortical state fluctuations to give rise to conscious perception? We addressed this question in the prefrontal cortex (PFC) by combining multi-electrode recordings with a binocular rivalry (BR) paradigm inducing spontaneously driven changes in the content of consciousness, inferred from the reflexive optokinetic nystagmus (OKN) pattern. We find that fluctuations between low-frequency (LF, 1-9 Hz) and beta (~20-40 Hz) local field potentials (LFPs) reflect competition between spontaneous updates and stability of conscious contents, respectively. Both LF and beta events were locally modulated. The phase of the former locked differentially to the competing populations just before a spontaneous transition while the latter synchronized the neuronal ensemble coding the consciously perceived content. These results suggest that prefrontal state fluctuations gate conscious perception by mediating internal states that facilitate perceptual update and stability.}, doi = {https://doi.org/10.1016/j.neuron.2023.02.027}, keywords = {consciousness, access, prefrontal cortex, mechanism, switching, binocular rivalry}, url = {https://www.sciencedirect.com/science/article/pii/S0896627323001319}, } @Article{ensel2023transient, author = {Ensel, Scott and Uhrig, Lynn and Ozkirli, Ayberk and Hoffner, Guylaine and Tasserie, Jordy and Dehaene, Stanislas and Van De Ville, Dimitri and Jarraya, B{\'e}chir and Pirondini, Elvira}, title = {Transient brain activity dynamics discriminate levels of consciousness during anesthesia}, journal = {bioRxiv}, year = {2023}, pages = {2023--10}, publisher = {Cold Spring Harbor Laboratory}, url = {https://www.biorxiv.org/content/10.1101/2023.10.09.560209v1.abstract}, } @Article{gennari2023spontaneous, author = {Gennari, Giulia and Dehaene, Stanislas and Valera, Chanel and Dehaene-Lambertz, Ghislaine}, title = {Spontaneous supra-modal encoding of number in the infant brain}, journal = {Current Biology}, year = {2023}, doi = {https://doi.org/10.1016/j.cub.2023.03.062}, publisher = {Elsevier}, url = {https://www.cell.com/current-biology/pdf/S0960-9822(23)00382-2.pdf}, } @Article{godel2023prosodic, author = {Godel, Michel and Robain, Fran{\c{c}}ois and Journal, Fiona and Kojovic, Nada and Latr{\`e}che, Kenza and Dehaene-Lambertz, Ghislaine and Schaer, Marie}, title = {Prosodic signatures of ASD severity and developmental delay in preschoolers}, journal = {NPJ Digital Medicine}, year = {2023}, volume = {6}, number = {1}, pages = {99}, publisher = {Nature Publishing Group UK London}, url = {https://www.nature.com/articles/s41746-023-00845-4}, } @Article{gunasekaran2022characterizing, author = {Gunasekaran, Harish and Azizi, Leila and van Wassenhove, Virginie and Herbst, Sophie K}, title = {Characterizing endogenous delta oscillations non-invasively in humans}, journal = {Scientific Reports}, year = {2023}, volume = {13}, pages = {11031}, doi = {https://doi.org/10.1038/s41598-023-37514-1}, publisher = {Cold Spring Harbor Laboratory}, url = {https://rdcu.be/dgjjZ}, } @Article{liu2023ultra, author = {Liu, Jianghao and Zhan, Minye and Hajhajate, Dounia and Spagna, Alfredo and Dehaene, Stanislas and Cohen, Laurent and Bartolomeo, Paolo}, title = {Ultra-high field fMRI of visual mental imagery in typical imagers and aphantasic individuals}, journal = {bioRxiv}, year = {2023}, pages = {2023--06}, publisher = {Cold Spring Harbor Laboratory}, url = {https://www.biorxiv.org/content/10.1101/2023.06.14.544909v4.abstract}, } @Article{lubineau2023does, author = {Lubineau, Marie and Watkins, Cassandra Potier and Glasel, Herv{\'e} and Dehaene, Stanislas}, title = {Does word flickering improve reading?

Previous work shows that deviant stimuli elicit phasic activation of the locus coeruleus (LC), which releases noradrenaline and controls central arousal. However, it is unclear whether the detection of behaviorally relevant deviant stimuli selectively triggers LC responses or other neuromodulatory systems (dopamine, serotonin, and acetylcholine). We combine human functional MRI (fMRI) recordings optimized for brainstem imaging with pupillometry to perform a mapping of deviant-related responses in subcortical structures. Participants have to detect deviant items in a "local-global" paradigm that distinguishes between deviance based on the stimulus probability and the sequence structure. fMRI responses to deviant stimuli are distributed in many cortical areas. Both types of deviance elicit responses in the pupil, LC, and other neuromodulatory systems.

In the case of literacy, there is a global consensus that early explicit phonics instruction is the best means to learning how to read. In this thesis, we propose a tablet-based game to support phonics learning. We also address several unanswered questions of teaching methodology. For example, during what period of time should the teaching of the phonetic method be introduced? Can children learn to read using phonics software before formal literacy? We present the results from our randomized control study with French first graders (N=975). Data collected from pre- and post- tests shows that children only benefited from the phonics game when it was used early in the school year. In a second intervention, we improved the design of the application and research methodology, and then tested the game with French kindergarteners (N=1092). This time students improved in factors that support literacy, irrelevant of the period that the games were used. However, in a follow-up test, benefits disappeared once formal reading education began. In the process of seeking to develop a tablet-based approach to literacy, we also describe a program used by the game engine that automatically creates a phonics progression based on the most frequent and consistent grapheme-phoneme correspondences for any alphabetic language. Historically, some of the greatest insights into the processes involved in reading have come from the examination of the deficits caused by brain lesions. Based on the hypothesis that reading is a complex cognitive activity, and that a deficit in any part of the process could lead to dyslexia, we developed a screener that looks at the types of errors made by readers to assess for selective deficits. After normalizing the screener with French 6th and 7th graders, we examine the different types of errors made by students previously diagnosed with dyslexia by their school. We present the first French cases of two different types of selective deficits: letter position dyslexia and attention dyslexia. The body of this work was developed with the goal of practical application. To this end, the tablet-based game and phonics builder code were developed using open-source software and licenses. Our screener for dyslexia is also open for use in collaboration with our lab. In the general discussion, we discuss ideas for immediate improvements and future studies that could be done using these tools, to the benefit of improved literacy programs for all students. }, } @Article{al2021mental, author = {Al Roumi, Fosca and Marti, S{\'e}bastien and Wang, Liping and Amalric, Marie and Dehaene, Stanislas}, title = {Mental compression of spatial sequences in human working memory using numerical and geometrical primitives}, journal = {Neuron}, year = {2021}, volume = {109}, number = {16}, pages = {2627--2639}, pdf = {http://www.unicog.org/publications/spatial_sequences_MEG_AlRoumi_Dehaene_2021}, publisher = {Elsevier}, } @Article{basso2021using, author = {Basso, Manuela A and Frey, Stephen and Guerriero, Kathryn A and Jarraya, B{\'e}chir and Kastner, Sabine and Koyano, Kenji W and Leopold, David A and Murphy, K and Poirier, Colline and Pope, W and others}, title = {Using non-invasive neuroimaging to enhance the care, well-being and experimental outcomes of laboratory non-human primates (monkeys)}, journal = {NeuroImage}, year = {2021}, volume = {228}, pages = {117667}, publisher = {Elsevier}, url = {https://www.sciencedirect.com/science/article/pii/S1053811920311526}, } @Article{bellet2021prefrontal, author = {Bellet, Marie Estelle and Gay, Marion and Bellet, Joachim and Jarraya, Bechir and Dehaene, Stanislas and van Kerkoerle, Timo and Panagiotaropoulos, Theofanis I}, title = {Prefrontal neural ensembles encode an internal model of visual sequences and their violations}, journal = {bioRxiv}, year = {2021}, pdf = {http://www.unicog.org/publications/2021.10.04.463064v1.full}, publisher = {Cold Spring Harbor Laboratory}, url = {https://www.biorxiv.org/content/10.1101/2021.10.04.463064v1}, } @Article{bellet2021spontaneously, author = {Bellet, Marie E and Gay, Marion and Bellet, Joachim and Jarraya, Bechir and Dehaene, Stanislas and van Kerkoerle, Timo and Panagiotaropoulos, Theofanis I}, title = {Spontaneously emerging internal models of visual sequences combine abstract and event-specific information in the prefrontal cortex}, journal = {bioRxiv}, year = {2021}, pages = {2021--10}, publisher = {Cold Spring Harbor Laboratory}, } @Article{benjamin2021remarks, author = {Benjamin, Lucas and Dehaene-Lambertz, Ghislaine and Fl{\'o}, Ana}, title = {Remarks on the analysis of steady-state responses: Spurious artifacts introduced by overlapping epochs}, journal = {Cortex}, year = {2021}, volume = {142}, pages = {370--378}, pdf = {http://www.unicog.org/publications/BenjaminFlo_SteadyState_Cortex2021}, publisher = {Elsevier}, } @Article{berkovitch2021disruption, author = {Berkovitch, Lucie and Charles, Lucie and Del Cul, Antoine and Hamdani, Nora and Delavest, Marine and Sarrazin, Samuel and Mangin, Jean-Fran{\c{c}}ois and Guevara, Pamela and Ji, Ellen and d'Albis, Marc-Antoine and others}, title = {Disruption of conscious access in psychosis is associated with altered structural brain connectivity}, journal = {Journal of Neuroscience}, year = {2021}, volume = {41}, number = {3}, pages = {513--523}, doi = {https://doi.org/10.1523/JNEUROSCI.0945-20.2020}, publisher = {Soc Neuroscience}, url = {https://doi.org/10.1523/JNEUROSCI.0945-20.2020}, } @Article{castaldi2021resources, author = {Castaldi, Elisa and Piazza, Manuela and Eger, Evelyn}, title = {Resources Underlying Visuo-Spatial Working Memory Enable Veridical Large Numerosity Perception}, journal = {Frontiers in Human Neuroscience}, year = {2021}, volume = {15}, pages = {751098}, publisher = {Frontiers}, url = {https://www.frontiersin.org/articles/10.3389/fnhum.2021.751098/full}, } @Article{choi2021neural, author = {Choi, Dawoon and Dehaene-Lambertz, Ghislaine and Pe{\~n}a, Marcela and Werker, Janet F}, title = {Neural indicators of articulator-specific sensorimotor influences on infant speech perception}, journal = {Proceedings of the National Academy of Sciences}, year = {2021}, volume = {118}, number = {20}, pdf = {http://www.unicog.org/publications/ChoiDehaeneLambertzPenaWerker_ArticulationmodifiedPacifier_PNAS2021_withSOM}, publisher = {National Acad Sciences}, } @Article{CICCIONE2021101406, author = {Lorenzo Ciccione and Stanislas Dehaene}, title = {Can humans perform mental regression on a graph?

Through a series of four behavioral experiments, we characterized human performance in "mental regression", i.e. the perception of statistical trends from scatterplots. When presented with a noisy scatterplot, even as briefly as 100 ms, human adults could accurately judge if it was increasing or decreasing, fit a regression line, and extrapolate outside the original data range, for both linear and non-linear functions. Performance was highly consistent across those three tasks of trend judgment, line fitting and extrapolation. Participants' linear trend judgments took into account the slope, the noise, and the number of data points, and were tightly correlated with the t-test classically used to evaluate the significance of a linear regression. However, they overestimated the absolute value of the regression slope. This bias was inconsistent with ordinary least squares (OLS) regression, which minimizes the sum of square deviations, but consistent with the use of Deming regression, which treats the x and y axes symmetrically and minimizes the Euclidean distance to the fitting line. We speculate that this fast but biased perception of scatterplots may be based on a "neuronal recycling" of the human visual capacity to identify the medial axis of a shape.}, doi = {https://doi.org/10.1016/j.cogpsych.2021.101406}, keywords = {Graph perception, Graphicacy, Trend judgment, Regression, Extrapolation, Scatterplot, Cognitive bias}, url = {https://www.sciencedirect.com/science/article/pii/S001002852100030X}, } @Article{cohen2021does, author = {Cohen, Laurent and Salondy, Philippine and Pallier, Christophe and Dehaene, Stanislas}, title = {How does inattention affect written and spoken language processing?}, journal = {Cortex}, year = {2021}, publisher = {Elsevier}, url = {https://www.sciencedirect.com/science/article/pii/S0010945221000642}, } @Article{davis2021spontaneous, author = {Davis, Zachary W and Benigno, Gabriel B and Fletterman, Charlee and Desbordes, Theo and Steward, Christopher and Sejnowski, Terrence J and H Reynolds, John and Muller, Lyle}, title = {Spontaneous traveling waves naturally emerge from horizontal fiber time delays and travel through locally asynchronous-irregular states}, journal = {Nature Communications}, year = {2021}, volume = {12}, number = {1}, pages = {1--16}, publisher = {Nature Publishing Group}, url = {https://www.nature.com/articles/s41467-021-26175-1}, } @Article{dehaene2021ouverture, author = {Dehaene, Stanislas and Christophe, Anne and Dehaene-Lambertz, Ghislaine and Izard, V{\'e}ronique and Pasquinelli, Elena and Spelke, Elizabeth}, title = {L'ouverture aux math{\'e}matiques {\`a} l'{\'e}cole maternelle et au CP}, journal = {Cons.

abstract pattern underlying a temporal sequence of events is crucial to many human activities, including language and mathematics, but its cortical correlates remain poorly understood. It is also unclear whether repeated exposure to the same sequence of sensory stimuli is sufficient to induce the encoding of an abstract amodal representation of the pattern. Using functional MRI, we probed the existence of such abstract codes for sequential patterns, their localization in the human brain, and their relation to existing language and math-responsive networks. We used a passive sequence violation paradigm, in which a given sequence is repeatedly presented before rare deviant sequences are introduced. We presented two binary patterns, AABB and ABAB, in four presentation formats, either visual or auditory, and either cued by the identity of the stimuli or by their spatial location. Regardless of the presentation format, a habituation to the repeated pattern and a response to pattern violations were seen in a set of inferior frontal, intraparietal and temporal areas. Within language areas, such pattern-violation responses were only found in the inferior frontal gyrus (IFG), whereas all math-responsive regions responded to pattern changes. Most of these regions also responded whenever the modality or the cue changed, suggesting a general sensitivity to violation detection. Thus, the representation of sequence patterns appears to be distributed, yet to include a core set of abstract amodal regions, particularly the IFG.}, doi = {https://doi.org/10.1016/j.cortex.2021.09.003}, keywords = {Sequence processing, Language, Abstract pattern, Novelty detection, Functional magnetic resonance imaging}, url = {https://www.sciencedirect.com/science/article/pii/S0010945221003038}, } @Article{planton2021theory, author = {Planton, Samuel and van Kerkoerle, Timo and Abbih, Le{\"\i}la and Maheu, Maxime and Meyniel, Florent and Sigman, Mariano and Wang, Liping and Figueira, Santiago and Romano, Sergio and Dehaene, Stanislas}, title = {A theory of memory for binary sequences: Evidence for a mental compression algorithm in humans}, journal = {PLoS computational biology}, year = {2021}, volume = {17}, number = {1}, pages = {e1008598}, publisher = {Public Library of Science San Francisco, CA USA}, url = {https://journals.plos.org/ploscompbiol/article?id=10.1371/journal.pcbi.1008598}, } @Article{sable2021sensitivity, author = {Sabl{\'e}-Meyer, Mathias and Fagot, Jo{\"e}l and Caparos, Serge and van Kerkoerle, Timo and Amalric, Marie and Dehaene, Stanislas}, title = {Sensitivity to geometric shape regularity in humans and baboons: A putative signature of human singularity}, journal = {Proceedings of the National Academy of Sciences}, year = {2021}, volume = {118}, number = {16}, publisher = {National Acad Sciences}, url = {https://www.pnas.org/content/118/16/e2023123118}, } @Article{sergent2021bifurcation, author = {Sergent, Claire and Corazzol, Martina and Labouret, Ghislaine and Stockart, Fran{\c{c}}ois and Wexler, Mark and King, Jean-R{\'e}mi and Meyniel, Florent and Pressnitzer, Daniel}, title = {Bifurcation in brain dynamics reveals a signature of conscious processing independent of report}, journal = {Nature Communications}, year = {2021}, volume = {12}, number = {1}, pages = {1--19}, publisher = {Nature Publishing Group}, url = {https://www.nature.com/articles/s41467-021-21393-z}, } @Article{signorelli2021towards, author = {Signorelli, Camilo Miguel and Meling, Daniel}, title = {Towards new concepts for a biological neuroscience of consciousness}, journal = {Cognitive Neurodynamics}, year = {2021}, pages = {1--22}, publisher = {Springer}, url = {https://link.springer.com/article/10.1007/s11571-020-09658-7}, } @Article{SIGNORELLI2021117618, author = {Camilo Miguel Signorelli and Lynn Uhrig and Morten Kringelbach and Bechir Jarraya and Gustavo Deco}, title = {Hierarchical disruption in the cortex of anesthetized monkeys as a new signature of consciousness loss}, journal = {NeuroImage}, year = {2021}, volume = {227}, pages = {117618}, issn = {1053-8119}, abstract = {Anesthesia induces a reconfiguration of the repertoire of functional brain states leading to a high function-structure similarity. However, it is unclear how these functional changes lead to loss of consciousness. Here we suggest that the mechanism of conscious access is related to a general dynamical rearrangement of the intrinsic hierarchical organization of the cortex. To measure cortical hierarchy, we applied the Intrinsic Ignition analysis to resting-state fMRI data acquired in awake and anesthetized macaques. Our results reveal the existence of spatial and temporal hierarchical differences of neural activity within the macaque cortex, with a strong modulation by the depth of anesthesia and the employed anesthetic agent. Higher values of Intrinsic Ignition correspond to rich and flexible brain dynamics whereas lower values correspond to poor and rigid, structurally driven brain dynamics. Moreover, spatial and temporal hierarchical dimensions are disrupted in a different manner, involving different hierarchical brain networks. All together suggest that disruption of brain hierarchy is a new signature of consciousness loss.}, doi = {https://doi.org/10.1016/j.neuroimage.2020.117618}, keywords = {Anesthesia, Integration, Ignition, Measures of Consciousness, IIT, GNW}, url = {https://www.sciencedirect.com/science/article/pii/S1053811920311034}, } @Article{watkins2021can, author = {Watkins, Cassandra Potier and Dehaene, Stanislas}, title = {Can a game application that boosts phonics knowledge in kindergarten advance 1st grade reading?}, year = {2021}, publisher = {PsyArXiv}, } @Misc{, author = {Algan, Y. and Dehaene, S. and Huillery, E. and Pasquinelli, E. and Ramus, F}, title = {Quels professeurs au XXIe siècle ?

Past research indicates that humans are sensitive to two types of sequential regularities: deterministic rules, which afford sure predictions, and statistical biases, which govern the probabilities of individual items and their transitions.

We used finger tracking to continuously monitor the online build-up of evidence, confidence, false alarms and changes-of-mind during sequence learning. All these aspects of behaviour conformed tightly to a hierarchical Bayesian inference model with distinct hypothesis spaces for statistics and rules, yet linked by a single probabilistic currency. Alternative models based either on a single statistical mechanism or on two non-commensurable systems were rejected.

This second release provides more data from psychological domains present in the first release, and also yields data featuring new ones. It includes tasks on e.g. mental time travel, reward, theory-of-mind, pain, numerosity, self-reference effect and speech recognition. In total, 13 tasks with 86 contrasts were added to the dataset and 63 new components were included in the cognitive description of the ensuing contrasts. As the dataset becomes larger, the collection of the corresponding topographies becomes more comprehensive, leading to better brain-atlasing frameworks.

They are not limited to emotional cries, alarm calls, and soothing demands; they also interpret the inner and outer world in a symbolic way, resulting in a collective intelligence and an accumulation of knowledge called culture. This culture permeates the child and fosters efficient learning, based on the knowledge accumulated through generations. To develop this collective intelligence, it requires (a) a social brain predisposed to learn from conspecifics, (b) awareness of one's mental state and knowledge and those of others, (c) a shared common language of thought, and (d) a communication system for exchanging this information. We insist on the value of symbolic representations as a compressed, necessary format for representing information to ourselves and exchanging information with others.

How does the human brain detect, identify, process and leverage those regularities in spite of their striking diversity? In this dissertation, I studied the mechanisms through which the human brain acquires knowledge of sequences and of regularities they may entail. To do so, I recorded behavioural and neural responses to auditory binary sequences characterized by various types of regularities. In parallel, I derived mathematical models of sequence processing that rest upon normative principles of probabilistic inference, but that are yet characterized by different computational architectures, and used human data to arbitrate among them. Using this same general approach, I investigated three different facets of the human sensitivity to sequences. Firstly, I demonstrated that a simple machinery for inferring transition structures between sequence items supports various aspects of the human perception of sequences encountered in seemingly disparate studies. Secondly, I then found that this learning algorithm was implemented in distinct brain systems which extracted statistical trends over different timescales, thereby providing a mechanistic explanation for the human sensitivity to both global statistical biases and to the recent history of observations. In addition to statistical learning, humans also possess the ability to quickly detect and identify deterministic rules. Thirdly, I showed that statistics and rules correspond to two distinct hypothesis spaces, instead of a continuum; and that human subjects could rationally arbitrate among them given the observed sequence. Altogether, my investigations of the cognitive foundations, computational principles and neural architectures supporting sequence processing suggest that the human brain is equipped with several systems that conform to normative principles of probabilistic inference but that are specialized in different aspects of sequences, thereby providing a putative explanation for the human perception of a vast repertoire of temporal regularities. }, } @InCollection{, author = {Stanislas Dehaene}, title = {Human Singularity and Symbolic Tree Structures}, booktitle = {The Neocortex}, publisher = {W.

such as long-distance number agreement. We have however no mechanistic understanding of how they accomplish this remarkable feat. Some have conjectured it depends on heuristics that do not truly take hierarchical structure into account. We present here a detailed study of the inner mechanics of number tracking in LSTMs at the single neuron level. We discover that long-distance number information is largely managed by two {``}number units{''}. Importantly, the behaviour of these units is partially controlled by other units independently shown to track syntactic structure. We conclude that LSTMs are, to some extent, implementing genuinely syntactic processing mechanisms, paving the way to a more general understanding of grammatical encoding in LSTMs.}, doi = {10.18653/v1/N19-1002}, pdf = {http://www.unicog.org/publications/N19-1002.pdf}, url = {https://www.aclweb.org/anthology/N19-1002}, } @InProceedings{lemaitre2019unearthing, author = {Lema{\^\i}tre, Herv{\'e} and Le Guen, Yann and Tilot, Amanda and Stein, Jason J and Philippe, Cathy and Mangin, Jean-Fran{\c{c}}ois and Frouin, Vincent and Fischer, Simon and Dehaene, Stanislas}, title = {Unearthing the Evolutionary History of Genetic Variants Influencing Human Sulcal Widening Authors: Introduction}, booktitle = {OHBM (Organization for Human Brain Mapping)}, year = {2019}, url = {https://hal.science/hal-02876133/file/HerveOHBM.pdf}, } @InProceedings{melloni2019computation, author = {Melloni, Lucia and Buffalo, Elizabeth A and Dehaene, Stanislas and Friston, Karl J and Ghazanfar, Asif A and Giraud, Anne-Lise and Grafton, Scott T and Haegens, Saskia and Pesaran, Bijan and Petkov, Christopher I and others}, title = {Computation and its neural implementation in human cognition}, booktitle = {Str{\"u}ngmann Forum Reports}, year = {2019}, volume = {27}, pages = {323--46}, url = {https://www.esforum.de/publications/PDFs/sfr27/SFR27_17_Melloni%20et%20al.pdf}, } @InProceedings{potier2019automatic, author = {Watkins, Cassandra Potier and Dehaene, Olivier and Dehaene, Stanislas}, title = {Automatic Construction of a Phonics Curriculum for Reading Education Using the Transformer Neural Network}, booktitle = {International Conference on Artificial Intelligence in Education}, year = {2019}, pages = {226--231}, organization = {Springer}, pdf = {http://www.unicog.org/publications/Potier-Watkins Dehaene Dehaene Phonics curriculum using the transformer network AIED2019}, url = {https://link.springer.com/chapter/10.1007/978-3-030-23207-8_42}, } @Misc{, author = {Jacobo Sitt , Jean-Remi King, Laurent Cohen, Lionel Naccache, and Stanislas Dehaene}, title = {Methods to monitor consciousness}, howpublished = {Patent}, year = {2019}, } @Book{casalis2018lire, title = {Lire-{\'e}crire: des savoirs scientifiques aux savoirs pratiques}, publisher = {Armand Colin}, year = {2018}, author = {Casalis, S{\'e}verine and Cohen, Laurent and Col{\'e}, Pascale and Dehaene, Stanislas and Fran{\c{c}}ois, Thomas and Gala, N{\'u}ria and Gentaz, Edouard and Javourey-Drevet, Ludivine and Kolinsky, R{\'e}gine and Lassault, Julie and others}, } @PhdThesis{, author = {Lucie BERKOVITCH}, title = {Processus impliqués dans le traitement des caractéristiques syntaxiques chez le sujet sain.

Structural and functional asymmetries are observed as early as the prenatal period suggesting genetically determined differences between both hemispheres. The corpus callosum is a large tract connecting mostly homologous areas; some have proposed that it might participate in an enhancement of the left-hemispheric advantage to process speech. To investigate its role in early development, we compared 13 3--4-month-old infants with an agenesis of the corpus callosum (``AgCC'') with 18 typical infants using high-density electroencephalography in an auditory task. We recorded event-related potentials for speech stimuli (syllables and babbling noise), presented binaurally (same syllable in both ears), monaurally (babbling noise in one ear) and dichotically (syllable in one ear and babbling noise in the other ear). In response to these stimuli, both groups developed an anterior positivity synchronous with a posterior negativity, yet the topography significantly differed between groups likely due to the atypical gyration of the medial surface in AgCC. In particular, the anterior positivity was lateral in AgCC infants while it covered the midline in typical infants. We then measured the latencies of the main auditory response (P2 at this age) for the different conditions on the symmetrical left and right clusters. The main difference between groups was a {\textasciitilde}{\thinspace}60ms delay in typical infants relative to AgCC, for the ipsilateral response (i.e. left hemisphere) to babbling noise presented in the left ear, whereas no difference was observed in the case of right-ear stimulation. We suggest that our results highlight an asymmetrical callosal connectivity favoring the right-to-left hemisphere direction in typical infants. This asymmetry, similar to recent descriptions in adults, might contribute to an enhancement of left lateralization for language processing beyond the initial cortical left-hemisphere advantage.}, Day = {23}, Doi = {10.1007/s00429-018-1667-4}, pdf = {http://www.unicog.org/publications/AdibpourDuboisDehaeneLambertz_ACC Auditoryresponses_BrStructFn2018.pdf}, ISSN = {1863-2661}, Owner = {gs985873}, Timestamp = {2018.04.24}, Url = {https://doi.org/10.1007/s00429-018-1667-4} } @Article{amalric2018cortical, Title = {Cortical circuits for mathematical knowledge: evidence for a major subdivision within the brain's semantic networks}, Author = {Amalric, Marie and Dehaene, Stanislas}, Journal = {Phil.

Autocorrelated Input Noise}, Author = {Schurger, Aaron}, Journal = {eNeuro}, Year = {2018}, Month = jan, Pages = {--}, Abstract = {Self-initiated movements are reliably preceded by a gradual buildup of neuronal activity known as the readiness potential (RP). Recent evidence suggests that the RP may reflect sub-threshold stochastic fluctuations in neural activity that can be modeled as a process of accumulation to bound. One element of accumulator models that has been largely overlooked in the literature is the stochastic term, which is traditionally modeled as Gaussian white noise. While there may be practical reasons for this choice, we have long known that noise in neural systems is not white as it is long-term correlated with spectral density of the form 1/f (with roughly 1 < < 3) across a broad range of spatial scales. I explored the behavior of a leaky stochastic accumulator when the noise over which it accumulates is temporally autocorrelated. I also allowed for the possibility that the RP, as measured at the scalp, might reflect the input to the accumulator (i.e. its stochastic noise component) rather than its output. These two premises led to two novel predictions that I empirically confirmed on behavioral and electroencephalography data from human subjects performing a self-initiated movement task. In addition to generating these two predictions, the model also suggested biologically plausible levels of autocorrelation, consistent with the degree of autocorrelation in our empirical data and in prior reports. These results expose new perspectives for accumulator models by suggesting that the spectral properties of the stochastic input should be allowed to vary, consistent with the nature of biological neural noise.Significance Statement The cortical â??readiness potentialâ?? (RP) is a gradual buildup of scalp electrical potential, and underlying neural activity in motor areas, that reliably precedes the onset of voluntary self-initiated movements by up to one second or more. More than fifty years after its discovery, the functional nature of the RP remains unclear. Here I argue, based on empirical evidence, that the RP reflects the stochastic input to an accumulation-to-bound decision process, and that this stochastic input is temporally autocorrelated, and not Gaussian white noise as it is traditionally modeled. The argument is supported by testing and confirming two novel predictions that emerge from an accumulator model when the stochastic input noise is autocorrelated rather than white.}, Owner = {GS985873}, Timestamp = {2018.04.10}, Url = {http://eneuro.org/content/early/2018/01/23/ENEURO.0302-17.2018.abstract} } @Article{uhrig2018resting, Title = {Resting-state Dynamics as a Cortical Signature of Anesthesia in Monkeys}, Author = {Uhrig, Lynn and Sitt, Jacobo D and Jacob, Amaury and Tasserie, Jordy and Barttfeld, Pablo and Dupont, Morgan and Dehaene, Stanislas and Jarraya, Bechir}, Journal = {Anesthesiology: The Journal of the American Society of Anesthesiologists}, Year = {2018}, pdf = {http://www.unicog.org/publications/Uhrig_et_al_Anesthesiology_2018.pdf}, } @Article{Vugt2018, Title = {The threshold for conscious report: Signal loss and response bias in visual and frontal cortex.}, Author = {van Vugt, B. and B.

In behavioral science, entrainment refers to the tendency of humans to synchronize their movements with rhythmic stimuli. Here, we asked whether human subjects performing a tapping task would entrain their tapping to an undetected auditory rhythm surreptitiously introduced in the guise of ambient background noise in the room. Subjects performed two different tasks, one in which they tapped their finger at a steady rate of their own choosing and one in which they performed a single abrupt finger tap on each trial after a delay of their own choosing. In both cases we found that subjects tended to tap in phase with the inducing modulation, with some variability in the preferred phase across subjects, consistent with prior research. In the repetitive tapping task, if the frequency of the inducing stimulus was far from the subjectâ??s own self-paced frequency, then entrainment was abolished, consistent with the properties of entrainment in physics. Thus, undetected ambient noise can influence self-generated movements.

Using novel words taught in the lab, we recorded Evoked Response Potentials (ERPs) in two-year-olds and adults listening to grammatical and ungrammatical sentences containing syntactic contexts that had not been used during training. In toddlers, the ungrammatical use of words, even when they have been just learned, induced an early left anterior negativity (surfacing 100-400ms after target word onset) followed by a late posterior positivity (surfacing 700-900ms after target word onset) that was not observed in grammatical sentences. This late effect was remarkably similar to the P600 displayed by adults, suggesting that toddlers and adults perform similar syntactic computations.

This entails categorizing words into their appropriate word classes. Function words, consistently preceding words from specific categories (e.g., the ballNOUN, I speakVERB), provide invaluable information for this task, and children's sensitivity to such adjacent relationships develops early on in life. However, neighboring words are not the sole source of information regarding an item's word class. Here we examine whether young children also take into account preceding sentence context online during syntactic categorization. To address this question, we use the ambiguous French function word la which, depending on sentence context, can either be used as determiner (the, preceding nouns) or as object clitic (it, preceding verbs). French-learning 18-month-olds' evoked potentials (ERPs) were recorded while they listened to sentences featuring this ambiguous function word followed by either a noun or a verb (thus yielding a locally felicitous co-occurrence of la + noun or la + verb). Crucially, preceding sentence context rendered the sentence either grammatical or ungrammatical. Ungrammatical sentences elicited a late positivity (resembling a P600) that was not observed for grammatical sentences. Toddlers' analysis of the unfolding sentence was thus not limited to local co-occurrences, but rather took into account non-adjacent sentence context. These findings suggest that by 18 months of age, online word categorization is already surprisingly robust.

Using a masking paradigm in normal adults, we recently discovered that some error-detection processes can proceed without awareness, while other markers of performance monitoring such as the Error-Related Negativity (ERN) are tightly linked to conscious perception. Interestingly, research on cognitive deficit in schizophrenia has shown that the ERN is altered in these patients. In the present study, we therefore tested if the error detection impairment in schizophrenia is specific to conscious perception or is also found under non-conscious conditions, probing whether these performance monitoring processes are truly distinct. Thirteen patients with schizophrenia and thirteen age-matched healthy control subjects performed a speeded number comparison task on masked stimuli while EEG and MEG signals were recorded. Conscious perception and error-detection were assessed on a trial-by-trial basis using subjective reports of visibility and confidence. We found that patients with schizophrenia presented altered cingulate error-detection responses in conscious trials, as reflected by a decreased ERN. By contrast, on unconscious trials, both controls and schizophrenia patients performed above chance in evaluating the likelihood of having made an error.

Here, we address this issue through the single-case longitudinal study of a neuroscientist who experienced pure alexia and participated in 17 behavioral, 9 anatomical, and 9 fMRI assessment sessions over a period of two years. The origin of the impairment was assigned to a small left fusiform lesion, accompanied by a loss of VWFA responsivity and by the degeneracy of the associated white matter pathways. fMRI experiments allowed us to image longitudinally the visual perception of words, as compared to other classes of stimuli, as well as the mechanisms of letter-by-letter reading. The progressive improvement of reading was not associated with the re-emergence of a new area selective to words, but with increasing responses in spared occipital cortex posterior to the lesion and in contralateral right occipital cortex. Those regions showed a non-specific increase of activations over time and an increase in functional correlation with distant language areas. Those results confirm the existence of an alternative occipital route for reading, bypassing the VWFA, but they also point to its key limitation: the patient remained a slow letter-by-letter reader, thus supporting the critical importance of the VWFA for the efficient parallel recognition of written words.}, Doi = {10.1016/j.neuropsychologia.2016.07.009}, Institution = {Department of Psychology, Royal Holloway, University of London, Egham, TW20 0EX, UK.}, Language = {eng}, Medline-pst = {aheadofprint}, Owner = {gs985873}, Pii = {S0028-3932(16)30253-6}, Pmid = {27422538}, Timestamp = {2016.07.25}, Url = {http://dx.doi.org/10.1016/j.neuropsychologia.2016.07.009} } @Article{Cusack2016, Title = {A neural window on the emergence of cognition.}, Author = {Cusack, Rhodri and Ball, Gareth and Smyser, Christopher D. and Dehaene-Lambertz, Ghislaine}, Journal = {Ann N Y Acad Sci}, Year = {2016}, Month = {Apr}, Number = {1}, Pages = {7--23}, Volume = {1369}, Abstract = {Can babies think? A fundamental challenge for cognitive neuroscience is to answer when brain functions begin and in what form they first emerge. This is challenging with behavioral tasks, as it is difficult to communicate to an infant what a task requires, and motor function is impoverished, making execution of the appropriate response difficult. To circumvent these requirements, neuroimaging provides a complementary route for assessing the emergence of cognition. Starting from the prerequisites of cognitive function and building stepwise, we review when the cortex forms and when it becomes gyrated and regionally differentiated. We then discuss when white matter tracts mature and when functional brain networks arise. Finally, we assess the responsiveness of these brain systems to external events. We find that many cognitive systems are observed surprisingly early. Some emerge before birth, with activations in the frontal lobe even in the first months of gestation. These discoveries are changing our understanding of the nature of cognitive networks and their early function, transforming cognitive neuroscience, and opening new windows for education and investigation. Infant neuroimaging also has tremendous clinical potential, for both detecting atypical development and facilitating earlier intervention.

For this, participants judged the ordinality of real historical events in time and in space with respect to different mental perspectives: for instance, participants mentally projected themselves in Paris in nine years, and judged whether an event occurred before or after, or, east or west, of where they mentally stood. In all three experiments, symbolic distance effects in time and space dimensions were quantified using Reaction Times (RT) and Error Rates (ER). When self-projected, participants were slower and were less accurate (absolute distance effects); participants were also faster and more accurate when the spatial and temporal distances were further away from their mental viewpoint (relative distance effects). These effects show that MTT and MSN require egocentric mapping and that self-projection requires map transformations.

Recent neuroscientific hypotheses propose that neural oscillations contribute to speech parsing, but whether they do so on the basis of acoustic cues (bottom-up acoustic parsing) or as a function of available linguistic representations (top-down linguistic parsing) is unknown. In this magnetoencephalography study, we contrasted acoustic and linguistic parsing using bistable speech sequences. While listening to the speech sequences, participants were asked to maintain one of the two possible speech percepts through volitional control. We predicted that the tracking of speech dynamics by neural oscillations would not only follow the acoustic properties but also shift in time according to the participant's conscious speech percept. Our results show that the latency of high-frequency activity (specifically, beta and gamma bands) varied as a function of the perceptual report. In contrast, the phase of low-frequency oscillations was not strongly affected by top-down control. While changes in low-frequency neural oscillations were compatible with the encoding of pre-lexical segmentation cues, high-frequency activity specifically informed on an individual's conscious speech percept.}, Doi = {10.1152/jn.00074.2016}, Institution = {CEA/DSV/I2BM/NeuroSpin.}, Language = {eng}, Medline-pst = {aheadofprint}, Owner = {gs985873}, Pii = {jn.00074.2016}, Pmid = {27605528}, Timestamp = {2016.10.05}, Url = {http://dx.doi.org/10.1152/jn.00074.2016} } @Article{Koesem2016a, Title = {Distinct contributions of low and high frequency neural oscillations to speech comprehension}, Author = {Anne K{\"{o}}sem and Virginie van Wassenhove}, Journal = {Language, Cognition and Language}, Year = {2016}, Owner = {gs985873}, Timestamp = {2016.10.05} } @Article{Mahmoudzadeh2016, Title = {Functional Maps at the Onset of Auditory Inputs in Very Early Preterm Human Neonates.}, Author = {Mahmoudzadeh, Mahdi and Wallois, Fabrice and Kongolo, Guy and Goudjil, Sabrina and Dehaene-Lambertz, Ghislaine}, Journal = {Cereb Cortex}, Year = {2016}, Month = {Apr}, Abstract = {During the last trimester of human gestation, neurons reach their final destination and establish long- and short-distance connections. Due to the difficulties obtaining functional data at this age, the characteristics of the functional architecture at the onset of sensory thalamocortical connectivity in humans remain largely unknown. In particular, it is unknown to what extent responses evoked by an external stimulus are general or already sensitive to certain stimuli. In the present study, we recorded high-density event-related potentials (ERPs) in 19 neonates, tested ten weeks before term (28-32 weeks gestational age (wGA), that is, at an average age of 30 wGA) by means of a syllable discrimination task (i.e., a phonetic change: ba vs. ga; and a voice change: male vs. female voice). We first observed that the syllables elicited 4 peaks with distinct topographies implying a progression of the sensory input along a processing hierarchy; second, repetition induced a decrease in the amplitude (repetition suppression) of these peaks, but their latencies and topographies remained stable; and third, a change of stimulus generated mismatch responses, which were more precisely time-locked to event onset in the case of a phonetic change than in the case of a voice change. A hierarchical and parallel functional architecture is therefore able to process environmental sounds in a timely precise fashion, well before term birth. This elaborate functional architecture at the onset of extrinsic neural activity suggests that specialized areas weakly dependent on the environment are present in the perisylvian region as part of the genetic endowment of the human species.}, Doi = {10.1093/cercor/bhw103}, pdf = {http://www.unicog.org/publications/Cereb_Cortex2016-Mahmoudzadeh.pdf}, Institution = {Cognitive Neuroimaging Unit, CEA DSV/I2BM, INSERM, CNRS, Université Paris-Sud, Université Paris-Saclay, NeuroSpin Center, Gif/Yvette 91191, France.}, Language = {eng}, Medline-pst = {aheadofprint}, Owner = {gs985873}, Pii = {bhw103}, Pmid = {27102655}, Timestamp = {2016.06.09}, Url = {http://dx.doi.org/10.1093/cercor/bhw103} } @Article{ManginJ-F2016, Title = {Spatial normalization of brain images and beyond}, Author = {Mangin, J-F and Lebenberg, J and Lefranc, S and Labra, N and Auzias, G and Labit, M and Guevara, M and Mohlberg, H and Roca, P and Guevara, P and Dubois, J and Leroy, F and Dehaene-Lambertz, G and Cachia, A and Dickscheid, T and Coulon, O and Poupon, C and Rivière, D and Amunts, K and Sun ZY}, Journal = {Medical Image Analysis}, Year = {2016}, Volume = {S1361-8415(16)30085-8.}, pdf = {http://www.unicog.org/publications/ManginSun_spatialNormalization_media16.pdf}, Owner = {gs985873}, Timestamp = {2017.12.01} } @Article{Meyniel2016, Title = {A specific role for serotonin in overcoming effort cost}, Author = {Meyniel, F. and Guy M Goodwin and JF William Deakin and Corinna Klingeand Christine MacFadyen and Holly Milligan and Emma Mullings and Mathias Pessiglione and Raphaël Gaillard}, Journal = {eLife}, Year = {2016}, Month = {November}, Owner = {gs985873}, Timestamp = {2016.12.12}, Url = {http://lens.elifesciences.org/17282/} } @Article{Meyniel2016a, Title = {Human inferences about sequences: A minimal transition probability model}, Author = {Meyniel, F. and M.

In primates, posterior parietal cortex seems to be a crucial site for this ability, even if the degree of selectivity of numerical representations in parietal cortex reported to date appears much lower compared to that of other semantic categories in the ventral stream. Number can also be intended as a mathematical object, which we humans use to count, measure, and order: a (verbal or visual) symbol that stands for the cardinality of a set, the intensity of a continuous quantity or the position of an item on a list.

Accordingly, a local morphological variability could lead to a corresponding functional variability. In this study, we tested this hypothesis by linking the variability of the cortical folding pattern of 252 right-handed subjects to the localization or the pattern of functional activations induced by hand motion or silent reading. Three regions are selected: the central sulcus, the precentral sulcus and the superior temporal sulcus (STS). "Essential morphological variability traits" are identified using a method building upon multidimensional scaling. The link between variability in anatomy and function is confirmed by the perfect match between the central sulcus morphological "hand knob" and the corresponding motor activation: as the location of the hand knob moves more or less dorsally along the central sulcus, the motor hand activation moves accordingly. Furthermore, the size of the left hand activation in the right hemisphere is correlated with the knob location in the central sulcus. A new link between functional and morphological variability is discovered relative to the location of a premotor activation induced by silent reading. While this reading activation is located next to the wall of the central sulcus when the hand knob has a ventral positioning, it is pushed into a deep gyrus interrupting the precentral sulcus when the knob is more dorsal. Finally, it is shown that the size of the reading activation along the STS is larger when the posterior branches are less developed.}, Doi = {10.1007/s00429-015-1106-8}, pdf = {http://www.unicog.org/publications/SunBrainStructFunction2016.pdf}, Institution = {CATI Multicenter Neuroimaging Platform, . jfmangin@cea.fr.}, Language = {eng}, Medline-pst = {ppublish}, Owner = {gs985873}, Pii = {10.1007/s00429-015-1106-8}, Pmid = {26346119}, Timestamp = {2016.10.03}, Url = {http://dx.doi.org/10.1007/s00429-015-1106-8} } @Article{Uhrig2016, Title = {Cerebral responses to local and global auditory novelty under general anesthesia.}, Author = {Uhrig, Lynn and Janssen, David and Dehaene, Stanislas and Jarraya, B{\'{e}}chir}, Journal = {Neuroimage}, Year = {2016}, Month = {Aug}, Pages = {326--340}, Volume = {141}, Abstract = {Primate brains can detect a variety of unexpected deviations in auditory sequences. The local-global paradigm dissociates two hierarchical levels of auditory predictive coding by examining the brain responses to first-order (local) and second-order (global) sequence violations. Using the macaque model, we previously demonstrated that, in the awake state, local violations cause focal auditory responses while global violations activate a brain circuit comprising prefrontal, parietal and cingulate cortices. Here we used the same local-global auditory paradigm to clarify the encoding of the hierarchical auditory regularities in anesthetized monkeys and compared their brain responses to those obtained in the awake state as measured with fMRI. Both, propofol, a GABAA-agonist, and ketamine, an NMDA-antagonist, left intact or even enhanced the cortical response to auditory inputs. The local effect vanished during propofol anesthesia and shifted spatially during ketamine anesthesia compared with wakefulness. Under increasing levels of propofol, we observed a progressive disorganization of the global effect in prefrontal, parietal and cingulate cortices and its complete suppression under ketamine anesthesia. Anesthesia also suppressed thalamic activations to the global effect. These results suggest that anesthesia preserves initial auditory processing, but disturbs both short-term and long-term auditory predictive coding mechanisms. The disorganization of auditory novelty processing under anesthesia relates to a loss of thalamic responses to novelty and to a disruption of higher-order functional cortical networks in parietal, prefrontal and cingular cortices.}, Doi = {10.1016/j.neuroimage.2016.08.004}, pdf = {http://unicog.org/publications/1-s2.0-S1053811916303822-main.pdf}, Institution = {CEA DRF/I2BM, NeuroSpin Center, 91191 Gif-sur-Yvette, France; INSERM U992, Cognitive Neuroimaging Unit, 91191 Gif-sur-Yvette, France; Neuromodulation Unit, Department of Neurosurgery, Foch Hospital, 92150 Suresnes, France; University of Versailles Saint-Quentin-en-Yvelines, Université Paris-Saclay, 78000 Versailles, France.

We measured dynamical functional connectivity with functional MRI during the resting state in awake and anesthetized monkeys. Under anesthesia, the more frequent functional connectivity patterns inherit the structure of anatomical connectivity, exhibit fewer small-world properties, and lack negative correlations. Conversely, wakefulness is characterized by the sequential exploration of a richer repertoire of functional configurations, often dissimilar to anatomical structure, and comprising positive and negative correlations among brain regions. These results reconcile theories of consciousness with observations of long-range correlation in the anesthetized brain and show that a rich functional dynamics might constitute a signature of consciousness, with potential clinical implications for the detection of awareness in anesthesia and brain-lesioned patients.}, Doi = {10.1073/pnas.1418031112}, pdf = {http://www.unicog.org/publications/Barttfeld Uhrig Sitt Sigman Jarraya Dehaene Signature of consciousness in resting state activity PNAS 2015.pdf}, Institution = {NeuroSpin Center, Institute of BioImaging Commissariat à l'Energie Atomique, 91191 Gif/Yvette, France; Cognitive Neuroimaging Unit, INSERM, U992, 91191 Gif/Yvette, France; Université Paris 11, 91405 Orsay, France; and Collège de France, 75005 Paris, France pablo.barttfeld@cea.fr bechir.jarraya@cea.fr stanislas.dehaene@cea.fr.}, Language = {eng}, Medline-pst = {ppublish}, Owner = {gs985873}, Pii = {1418031112}, Pmid = {25561541}, Timestamp = {2015.02.23}, Url = {http://dx.doi.org/10.1073/pnas.1418031112} } @Article{Benezit2014, Title = {Organising white matter in a brain without corpus callosum fibres.}, Author = {Bénézit, Audrey and Hertz-Pannier, Lucie and Dehaene-Lambertz, Ghislaine and Monzalvo, Karla and Germanaud, David and Duclap, Delphine and Guevara, Pamela and Mangin, Jean-François and Poupon, Cyril and Moutard, Marie-Laure and Dubois, Jessica}, Journal = {Cortex}, Year = {2015}, Month = {Sep}, Pages = {155--171}, Volume = {63C}, Abstract = {Isolated corpus callosum dysgenesis (CCD) is a congenital malformation which occurs during early development of the brain.

Seven children aged between 9 and 13 years old and seven age- and gender-matched control children were studied. First, we focused on bundles within the mesial region of the cerebral hemispheres: the corpus callosum, Probst bundles and cingulum which were selected using a conventional region-based approach. We demonstrated that the Probst bundles have a wider connectivity than the previously described rostrocaudal direction, and a microstructure rather distinct from the cingulum but relatively close to callosal remnant fibres. A sigmoid bundle was found in two partial ageneses. Second, the corticospinal tract, thalamic radiations and association bundles were extracted automatically via an atlas of adult white matter bundles to overcome bias resulting from a priori knowledge of the bundles' anatomical morphology and trajectory. Despite the lack of callosal fibres and the colpocephaly observed in CCD, all major white matter bundles were identified with a relatively normal morphology, and preserved microstructure (i.e. fractional anisotropy, mean diffusivity) and asymmetries. Consequently the bundles' organisation seems well conserved in brains with CCD.

The estimation of the spatial covariance of the signals recorded on M/EEG sensors is a building block of modern data analysis pipelines. Such covariance estimates are used in brain-computer interfaces (BCI) systems, in nearly all source localization methods for spatial whitening as well as for data covariance estimation in beamformers. The rationale for such models is that the signals can be modeled by a zero mean Gaussian distribution. While maximizing the Gaussian likelihood seems natural, it leads to a covariance estimate known as empirical covariance (EC). It turns out that the EC is a poor estimate of the true covariance when the number of samples is small. To address this issue the estimation needs to be regularized. The most common approach downweights off-diagonal coefficients, while more advanced regularization methods are based on shrinkage techniques or generative models with low rank assumptions: probabilistic PCA (PPCA) and factor analysis (FA). Using cross-validation all of these models can be tuned and compared based on Gaussian likelihood computed on unseen data. We investigated these models on simulations, one electroencephalography (EEG) dataset as well as magnetoencephalography (MEG) datasets from the most common MEG systems. First, our results demonstrate that different models can be the best, depending on the number of samples, heterogeneity of sensor types and noise properties. Second, we show that the models tuned by cross-validation are superior to models with hand-selected regularization. Hence, we propose an automated solution to the often overlooked problem of covariance estimation of M/EEG signals.

To investigate this, we examined brain activation and connectivity in 19 subjects who read sentences and viewed pictures depicting everyday events, in a combined fMRI and DTI study. Conjunction of activity in understanding sentences and pictures revealed a common fronto-temporo-parietal network that included the middle and inferior frontal gyri, the parahippocampal-retrosplenial complex, the anterior and middle temporal gyri, the inferior parietal lobe in particular the temporo-parietal cortex. DTI tractography seeded from this temporo-parietal cortex hub revealed a multi-component network reaching into the temporal pole, the ventral frontal pole and premotor cortex. A significant correlation was found between the relative pathway density issued from the temporo-parietal cortex and the imageability of sentences for individual subjects, suggesting a potential functional link between comprehension and the temporo-parietal connectivity strength. These data help to define a "meaning" network that includes components of recently characterized systems for semantic memory, embodied simulation, and visuo-spatial scene representation. The network substantially overlaps with the "default mode" network implicated as part of a core network of semantic representation, along with brain systems related to the formation of mental models, and reasoning.

This 45-mm-long segment ventral to Heschl's gyrus is deeper in the right hemisphere than in the left in 95\% of typical human subjects, from infanthood till adulthood, and is present, irrespective of handedness, language lateralization, and sex although it is greater in males than in females. The STAP also is seen in several groups of atypical subjects including persons with situs inversus, autistic spectrum disorder, Turner syndrome, and corpus callosum agenesis. It is explained in part by the larger number of sulcal interruptions in the left than in the right hemisphere. Its early presence in the infants of this study as well as in fetuses and premature infants suggests a strong genetic influence. Because this asymmetry is barely visible in chimpanzees, we recommend the STAP region during midgestation as an important phenotype to investigate asymmetrical variations of gene expression among the primate lineage.

Limits in subjective reports stemmed from both the number and the type of eye movements. Furthermore, subjects sometimes reported eye movements they actually never made. A detailed examination of these reports suggests that they could reflect covert shifts of attention during overt serial search.

A consonant change evoked a significant difference around the second auditory peak (400-600 ms) relative to control trials.

However, many classical models reduce the learning process to the updating of parameter estimates and neglect the fact that learning is also frequently accompanied by a variable "feeling of knowing" or confidence. The characteristics and the origin of these subjective confidence estimates thus remain largely unknown. Here we investigate whether, during learning, humans not only infer a model of their environment, but also derive an accurate sense of confidence from their inferences. In our experiment, humans estimated the transition probabilities between two visual or auditory stimuli in a changing environment, and reported their mean estimate and their confidence in this report. To formalize the link between both kinds of estimate and assess their accuracy in comparison to a normative reference, we derive the optimal inference strategy for our task. Our results indicate that subjects accurately track the likelihood that their inferences are correct. Learning and estimating confidence in what has been learned appear to be two intimately related abilities, suggesting that they arise from a single inference process. We show that human performance matches several properties of the optimal probabilistic inference. In particular, subjective confidence is impacted by environmental uncertainty, both at the first level (uncertainty in stimulus occurrence given the inferred stochastic characteristics) and at the second level (uncertainty due to unexpected changes in these stochastic characteristics). Confidence also increases appropriately with the number of observations within stable periods. Our results support the idea that humans possess a quantitative sense of confidence in their inferences about abstract non-sensory parameters of the environment. This ability cannot be reduced to simple heuristics, it seems instead a core property of the learning process.}, Doi = {10.1371/journal.pcbi.1004305}, pdf = {http://www.unicog.org/publications/MeynielSchluneggerDehaene_2015_PCB_The-sense-of-confidence-during-probabilistic-learning-A-normative-account.pdf}, Institution = {Cognitive Neuroimaging Unit, U992, INSERM, Gif/Yvette, France; NeuroSpin Center, DSV/I2BM, CEA, Gif/Yvette, France; Collège de France, Paris, France.}, Language = {eng}, Medline-pst = {epublish}, Owner = {gs985873}, Pii = {PCOMPBIOL-D-15-00200}, Pmid = {26076466}, Timestamp = {2015.06.29}, Url = {http://dx.doi.org/10.1371/journal.pcbi.1004305} } @Article{Meyniel2015a, Title = {Confidence as Bayesian Probability: From Neural Origins to Behavior.}, Author = {Meyniel, Florent and Sigman, Mariano and Mainen, Zachary F.}, Journal = {Neuron}, Year = {2015}, Month = {Oct}, Number = {1}, Pages = {78--92}, Volume = {88}, Abstract = {Research on confidence spreads across several sub-fields of psychology and neuroscience.

While both forms of decision process have been studied empirically, the precise relationship between them remains poorly understood. We performed an experiment that combined a perceptual decision-making task (identifying the category of a faint visual stimulus) with a confidence-judgement task (wagering on the accuracy of each perceptual decision). The visual stimulation paradigm required steady fixation, so we used eye-tracking to control for stray eye movements. Our data analyses revealed an unexpected and counterintuitive interaction between the steadiness of fixation (prior to and during stimulation), perceptual decision making, and post-decision wagering: greater variability in gaze direction during fixation was associated with significantly increased visual-perceptual sensitivity, but significantly decreased reliability of confidence judgements. The latter effect could not be explained by a simple change in overall confidence (i.e. a criterion artifact), but rather was tied to a change in the degree to which high wagers predicted correct decisions (i.e. the sensitivity of the confidence judgement). We found no evidence of a differential change in pupil diameter that could account for the effect and thus our results are consistent with fixational eye movements being the relevant covariate. However, we note that small changes in pupil diameter can sometimes cause artefactual fluctuations in measured gaze direction and this possibility could not be fully ruled out. In either case, our results suggest that perceptual decisions and confidence judgements can be processed independently and point toward a new avenue of research into the relationship between them.}, Doi = {10.1371/journal.pone.0125278}, Institution = {Department of Psychology, Princeton University, Princeton, New Jersey, United States of America; Princeton Neuroscience Institute, Princeton University, Princeton, New Jersey, United States of America.}, Language = {eng}, Medline-pst = {epublish}, Owner = {gs985873}, Pii = {PONE-D-15-01700}, Pmid = {25955162}, Timestamp = {2015.05.27}, Url = {http://dx.doi.org/10.1371/journal.pone.0125278} } @Article{Schurger2015b, Title = {Cortical activity is more stable when sensory stimuli are consciously perceived.}, Author = {Schurger, Aaron and Sarigiannidis, Ioannis and Naccache, Lionel and Sitt, Jacobo D. and Dehaene, Stanislas}, Journal = {Proc Natl Acad Sci U S A}, Year = {2015}, Month = {Apr}, Number = {16}, Pages = {E2083--E2092}, Volume = {112}, Abstract = {According to recent evidence, stimulus-tuned neurons in the cerebral cortex exhibit reduced variability in firing rate across trials, after the onset of a stimulus. However, in order for a reduction in variability to be directly relevant to perception and behavior, it must be realized within trial--the pattern of activity must be relatively stable. Stability is characteristic of decision states in recurrent attractor networks, and its possible relevance to conscious perception has been suggested by theorists. However, it is difficult to measure on the within-trial time scales and broadly distributed spatial scales relevant to perception. We recorded simultaneous magneto- and electroencephalography (MEG and EEG) data while subjects observed threshold-level visual stimuli. Pattern-similarity analyses applied to the data from MEG gradiometers uncovered a pronounced decrease in variability across trials after stimulus onset, consistent with previous single-unit data. This was followed by a significant divergence in variability depending upon subjective report (seen/unseen), with seen trials exhibiting less variability. Applying the same analysis across time, within trial, we found that the latter effect coincided in time with a difference in the stability of the pattern of activity. Stability alone could be used to classify data from individual trials as "seen" or "unseen." The same metric applied to EEG data from patients with disorders of consciousness exposed to auditory stimuli diverged parametrically according to clinically diagnosed level of consciousness. Differences in signal strength could not account for these results.

Together, these have provided a large fundus of information on many different aspects of the human brain including micro- and macrostructural segregation, regional specialization of function, connectivity, and temporal dynamics. Atlases are central in order to integrate such diverse information in a topographically meaningful way. It is noteworthy, that the brain mapping field has been developed along several major lines such as structure vs. function, postmortem vs. in vivo, individual features of the brain vs. population-based aspects, or slow vs. fast dynamics. In order to understand human brain organization, however, it seems inevitable that these different lines are integrated and combined into a multimodal human brain model. To this aim, we held a workshop to determine the constraints of a multi-modal human brain model that are needed to enable (i) an integration of different spatial and temporal scales and data modalities into a common reference system, and (ii) efficient data exchange and analysis. As detailed in this report, to arrive at fully interoperable atlases of the human brain will still require much work at the frontiers of data acquisition, analysis, and representation. Among them, the latter may provide the most challenging task, in particular when it comes to representing features of vastly different scales of space, time and abstraction.

Do infants already possess such a hierarchy of violation-detection mechanisms? Using high-density recordings of event-related potentials during an auditory local-global violation paradigm, we show that three-month-old infants process novelty in temporal sequences at two distinct levels. Violations of local expectancies, such as perceiving a deviant vowel "a" after repeated presentation of another vowel i-i-i, elicited an early auditory mismatch response. Conversely, violations of global expectancies, such as hearing the rare sequence a-a-a-a instead of the frequent sequence a-a-a-i, modulated this early mismatch response and led to a late frontal negative slow wave, whose cortical sources included the left inferior frontal region.

Although the baby's brain is organized early on, it is not a miniature adult brain: regional brain changes are asynchronous and protracted, i.e. sensory-motor regions develop early and quickly, whereas associative regions develop later and slowly over decades. Concurrently, the infant/child gradually achieves new performances, but how brain maturation relates to changes in behavior is poorly understood, requiring non-invasive in vivo imaging studies such as magnetic resonance imaging (MRI). Two main processes of early white matter development are reviewed: (1) establishment of connections between brain regions within functional networks, leading to adult-like organization during the last trimester of gestation, (2) maturation (myelination) of these connections during infancy to provide efficient transfers of information.

We thus recorded 9 epileptic patients with intracranial electrodes to compare the precise dynamics of the responses to local and global novelty. Local novelty triggered an early response observed as an intracranial mismatch negativity (MMN) contemporary with a strong power increase in the gamma band and an increase in connectivity in the beta band.

In contrast, global novelty gave rise to a late ERP response distributed across brain areas, contemporary with a sustained power decrease in the beta band (13-25 Hz) and an increase in connectivity in the alpha band (8-13 Hz) within the frontal lobe.

Here, using MRI, we examined the relations between the 10-20 sensor placement system and cerebral structures in 16 infants (3-17 weeks post-term). We provided an infant template parcelled in 94 regions on which we reported the variability of sensors locations, concurrently with the anatomical variability of six main cortical sulci (superior and inferior frontal sulcus, central sulcus, sylvian fissure, superior temporal sulcus, and intraparietal sulcus) and of the distances between the sensors and important cortical landmarks across these infants. The main difference between infants and adults was observed for the channels O1-O2, T5-T6, which projected over lower structures than in adults. We did not find any asymmetry in the distances between the scalp and the brain envelope. However, because of the Yakovlean torque pushing dorsally and frontally the right sylvian fissure, P3-P4 were not at the same distance from the posterior end of this structure.

By formalizing, within the same framework, forced-choice discrimination responses, subjective visibility reports and confidence ratings, we show that this decision model suffices to account for several classical characteristics of conscious and unconscious perception. Furthermore, the model provides a set of original predictions on the nonlinear profiles of discrimination performance obtained at various levels of visibility. We successfully test one such prediction in a novel experiment: when varying continuously the degree of perceptual ambiguity between two visual symbols presented at perceptual threshold, identification performance varies quasi-linearly when the stimulus is unseen and in an 'all-or-none' manner when it is seen.

Such multi-parametric approach is expected to better describe maturational asynchrony than conventional univariate approaches because it takes into account complementary dependencies of the parameters on different maturational processes, notably the decrease in water content and the myelination. Our approach was tested on 17 healthy infants (aged 3- to 21-week old) for 18 different bundles. It finely confirmed maturational asynchrony across the bundles: the spino-thalamic tract, the optic radiations, the cortico-spinal tract and the fornix have the most advanced maturation, while the superior longitudinal and arcuate fasciculi, the anterior limb of the internal capsule and the external capsule have the most delayed maturation. Furthermore, this approach was more reliable than univariate approaches as it revealed more maturational relationships between the bundles and did not violate a priori assumptions on the temporal order of the bundle maturation. Mahalanobis distances decreased exponentially with age in all bundles, with the only difference between them explained by different onsets of maturation. Estimation of these relative delays confirmed that the most dramatic changes occur during the first post-natal year.}, Doi = {10.1007/s00429-014-0881-y}, pdf = {http://www.unicog.org/publications/KulikovaDubois_mahalanobis_brainStructFunct14.pdf}, Institution = {UMR 1129 NeuroSpin/UNIACT, INSERM-CEA, Gif-sur-Yvette, France.}, Language = {eng}, Medline-pst = {aheadofprint}, Owner = {gs985873}, Pmid = {25183543}, Timestamp = {2014.11.07}, Url = {http://dx.doi.org/10.1007/s00429-014-0881-y} } @Article{Koesem2014, Title = {Encoding of event timing in the phase of neural oscillations}, Author = {Kösem, Anne and Gramfort, Alexandre and {van Wassenhove}, Virginie}, Journal = {Neuroimage}, Year = {2014}, Month = {Feb}, Pages = {274--284}, Volume = {92C}, Abstract = {Time perception is a critical component of conscious experience. To be in synchrony with the environment, the brain must deal not only with differences in the speed of light and sound but also with its computational and neural transmission delays. Here, we asked whether the brain could actively compensate for temporal delays by changing its processing time. Specifically, can changes in neural timing or in the phase of neural oscillation index perceived timing? For this, a lag-adaptation paradigm was used to manipulate participants' perceived audiovisual (AV) simultaneity of events while they were recorded with magnetoencephalography (MEG). Desynchronized AV stimuli were presented rhythmically to elicit a robust 1Hz frequency-tagging of auditory and visual cortical responses. As participants' perception of AV simultaneity shifted, systematic changes in the phase of entrained neural oscillations were observed. This suggests that neural entrainment is not a passive response and that the entrained neural oscillation shifts in time. Crucially, our results indicate that shifts in neural timing in auditory cortices linearly map participants' perceived AV simultaneity. To our knowledge, these results provide the first mechanistic evidence for active neural compensation in the encoding of sensory event timing in support of the emergence of time awareness.}, Doi = {10.1016/j.neuroimage.2014.02.010}, pdf = {http://www.unicog.org/publications/1-s2.0-S1053811914001013-main.pdf}, Institution = {INSERM, U992, Cognitive Neuroimaging Unit, F-91191 Gif/Yvette, France; CEA, DSV/I2BM, NeuroSpin Center, F-91191 Gif/Yvette, France; Univ Paris-Sud, Cognitive Neuroimaging Unit, F-91191 Gif/Yvette, France.

There is evidence that short range or 'local' regularities (within seconds) are automatically detected by the brain while long range or 'global' regularities (over tens of seconds or more) require conscious awareness. In the present experiment, we asked whether participants' attention was needed to acquire such auditory regularities, to detect their violation or both. We designed a paradigm in which participants listened to predictable sounds. Subjects could be distracted by a visual task at two moments: when they were first exposed to a regularity or when they detected violations of this regularity. MEG recordings revealed that early brain responses (100-130 ms) to violations of short range regularities were unaffected by visual distraction and driven essentially by local transitional probabilities. Based on global workspace theory and prior results, we expected that visual distraction would eliminate the long range global effect, but unexpectedly, we found the contrary, i.e. late brain responses (300-600 ms) to violations of long range regularities on audio-visual trials but not on auditory only trials. Further analyses showed that, in fact, visual distraction was incomplete and that auditory and visual stimuli interfered in both directions. Our results show that conscious, attentive subjects can learn the long range dependencies present in auditory stimuli even while performing a visual task on synchronous visual stimuli. Furthermore, they acquire a complex regularity and end up making different predictions for the very same stimulus depending on the context (i.e. absence or presence of visual stimuli). These results suggest that while short-range regularity detection is driven by local transitional probabilities between stimuli, the human brain detects and stores long-range regularities in a highly flexible, context dependent manner.}, Doi = {10.1371/journal.pone.0107227}, pdf = {http://www.unicog.org/publications/Marti Thibault Dehaene 2014 PLoSone_ Extraction of regularities varies with context.pdf}, Institution = {INSERM, U992, Cognitive Neuroimaging Unit, Gif/Yvette, France; CEA, DSV/I2BM, NeuroSpin Center, Gif/Yvette, France; Collège de France, Paris, France.}, Language = {eng}, Medline-pst = {epublish}, Owner = {gs985873}, Pii = {PONE-D-14-14573}, Pmid = {25197987}, Timestamp = {2014.11.07}, Url = {http://dx.doi.org/10.1371/journal.pone.0107227} } @Article{Pegado2014a, Title = {Timing the impact of literacy on visual processing.}, Author = {Pegado, Felipe and Comerlato, Enio and Ventura, Fabricio and Jobert, Antoinette and Nakamura, Kimihiro and Buiatti, Marco and Ventura, Paulo and Dehaene-Lambertz, Ghislaine and Kolinsky, Regine and Morais, Jose and Braga, Lucia W. and Cohen, Laurent and Dehaene, Stanislas}, Journal = {Proc Natl Acad Sci U S A}, Year = {2014}, Month = {Dec}, Number = {49}, Pages = {E5233--E5242}, Volume = {111}, Abstract = {Learning to read requires the acquisition of an efficient visual procedure for quickly recognizing fine print.

To clarify whether literacy affects early vs. late stages of visual processing, we measured event-related potentials to various categories of visual stimuli in healthy adults with variable levels of literacy, including completely illiterate subjects, early-schooled literate subjects, and subjects who learned to read in adulthood (ex-illiterates). The stimuli included written letter strings forming pseudowords, on which literacy is expected to have a major impact, as well as faces, houses, tools, checkerboards, and false fonts. To evaluate the precision with which these stimuli were encoded, we studied repetition effects by presenting the stimuli in pairs composed of repeated, mirrored, or unrelated pictures from the same category. The results indicate that reading ability is correlated with a broad enhancement of early visual processing, including increased repetition suppression, suggesting better exemplar discrimination, and increased mirror discrimination, as early as ? 100-150 ms in the left occipitotemporal region.

To evaluate this hypothesis, we asked adult literates, illiterates, and ex-illiterates to perform a speeded same-different task with letter strings, false fonts, and pictures regardless of their orientation (i.e., they had to respond "same" to mirror pairs such as "iblo oldi").

Far from shutting down all brain activity, anesthetics lead to a shift in the brain state to a distinct, highly specific and complex state, which is being increasingly characterized by modern neuro-imaging techniques.

Can language circuits process simple grammatical constructions unconsciously and integrate the meaning of several unseen words? Using behavioural priming and electroencephalography (EEG), we studied a specific rule-based linguistic operation traditionally thought to require conscious cognitive control: the negation of valence. In a masked priming paradigm, two masked words were successively (Experiment 1) or simultaneously presented (Experiment 2), a modifier ('not'/'very') and an adjective (e.g. 'good'/'bad'), followed by a visible target noun (e.g. 'peace'/'murder'). Subjects indicated whether the target noun had a positive or negative valence. The combination of these three words could either be contextually consistent (e.g. 'very bad - murder') or inconsistent (e.g. 'not bad - murder'). EEG recordings revealed that grammatical negations could unfold partly unconsciously, as reflected in similar occipito-parietal N400 effects for conscious and unconscious three-word sequences forming inconsistent combinations.

Using MagnetoEncephaloGraphy (MEG), we tested whether increased neural activity during surprise and following neural suppression in two different contexts supported subjective time dilation (Eagleman & Pariyadath, 2009; Pariyadath & Eagleman, 2012). Sequences of three 300ms frequency-modulated (FM, control) or pure tones (test) were presented and followed by a fourth FM varying in duration. In test, the last FM was perceived as significantly longer than veridical duration (Tse, Intriligator, Rivest, & Cavanagh, 2004) but did not differ from the perceived duration in control. Several novel and distinct neural signatures were observed in duration estimation: first, neural suppression of standard stimuli was observed for the onset but not for the offset auditory evoked responses. Second, ramping activity increased with veridical duration in control whereas at the same latency in test, the amplitude of the midlatency response increased with the distance of deviant durations. Third, in both conditions, the amplitude of the offset auditory evoked responses accounted well for participants' performance: the longer the perceived duration, the larger the offset response. Fourth, neural duration demarcated by the peak latencies of the onset and ramping evoked activities indexed a systematic time compression that reliably predicted subjective time perception. Our findings suggest that interval timing undergoes time compression by capitalizing on the predicted offset of an auditory event.}, Doi = {10.1016/j.neuroimage.2014.11.005}, Institution = {CEA, DSV/I(2)BM, NeuroSpin, INSERM, U992, Cognitive Neuroimaging Unit, Univ Paris-Sud F-91191 Gif/Yvette, France.}, Language = {eng}, Medline-pst = {aheadofprint}, Owner = {gs985873}, Pii = {S1053-8119(14)00907-0}, Pmid = {25462792}, Timestamp = {2014.12.04}, Url = {http://dx.doi.org/10.1016/j.neuroimage.2014.11.005} } @Article{Viarouge2014, Title = {The Organization of Spatial Reference Frames Involved in the SNARC Effect}, Author = {Viarouge, Arnaud and Hubbard, Edward M. and Dehaene, Stanislas}, Journal = {Q J Exp Psychol (Hove)}, Year = {2014}, Month = {Feb}, Abstract = {Abstract The SNARC effect refers to faster reaction times for larger numbers with right-sided responses, and for smaller numbers with left-sided responses (Dehaene et al., 1993), even when numerical magnitude is irrelevant. Although the SNARC is generally thought to reflect a mapping between numbers and space, the question of which spatial reference frame(s) are critical for the effect has not been systematically explored. We propose a dynamic hierarchical organization of the reference frames (from a global left-right frame to body- and object-related frames), where the influence of each frame can be modulated by experimental context. We conducted two experiments based on predictions derived from this organizational system. Experiment 1 compared instructions that differed only in focusing participants' attention on either the response buttons or the hands. Instructions focusing on a hand-based reference frame eliminated the SNARC. Experiment 2 provided the opportunity for an object-centered reference frame to manifest itself in the SNARC. Although we did not observe an effect of an object-centered reference frame, we observed the influence of other reference frames in a context where an object-centered reference frame was emphasized.

We applied a subject-by-subject functionally guided approach on a total of 76 participants (31 dyslexic children). Cortical thickness was estimated for each participant around his/her peak of specific functional activation to visual words, faces, or places. Results from two independent datasets showed a reduction in thickness in dyslexic children compared with controls in the region responsive to words, in the left hemisphere. Additionally, a gender-by-diagnosis interaction was observed at the same location, due to differences in girls only. To avoid the potential confound of reading level, we also contrasted dyslexic and control children matched for reading performance, and we observed a similar difference, although in a smaller extent of cortex.

Here, we used simultaneous electro- and magneto-encephalography (EEG/MEG) to investigate how error detection is modulated by perceptual awareness of a masked target digit. The Error-Related Negativity (ERN), an EEG component occurring ~100 ms after an erroneous response, was exclusively observed on conscious trials: regardless of masking strength, the amplitude of the ERN showed a step-like increase when the stimulus became visible. Nevertheless, even in the absence of an ERN, participants still managed to detect their errors at above-chance levels under subliminal conditions. Error detection on conscious trials originated from the posterior cingulate cortex, while a small response to non-conscious errors was seen in dorsal anterior cingulate.

We then used multivariate pattern recognition on high-resolution functional magnetic resonance imaging (fMRI) data acquired before and after this game to test whether neural responses to the partners' and neutral control faces during a perceptual task reflect their learned social valence. Support vector classification scores revealed a learning-related increase in neural discrimination of social status in anterior insula and anterior cingulate regions, which was mainly driven by includer faces becoming distinguishable from excluder and control faces. Thus, face-evoked responses in anterior insula and anterior cingulate cortex contain fine-grained information shaped by prior social interactions that allow for categorisation of faces according to their learned social status.

Fifteen patients with schizophrenia and 15 control subjects participated in this functional magnetic resonance imaging (fMRI) study. Participants were told that whenever they saw a word on the screen, they had to read it silently to themselves (read and repeat conditions), and when they saw a dot, they had to think of the just-previous word (refresh condition).

To tackle this issue, we recently designed a paradigm that dissociates two electro-encephalographic (EEG) responses to auditory novelty. Whereas a local change in pitch automatically elicits a mismatch negativity (MMN), a change in global sound sequence leads to a late P300b response. The latter component is thought to be present only when subjects consciously perceive the global novelty. Unfortunately, it can be difficult to detect because individual variability is high, especially in clinical recordings. Here, we show that multivariate pattern classifiers can extract subject-specific EEG patterns and predict single-trial local or global novelty responses. We first validate our method with 38 high-density EEG, MEG and intracranial EEG recordings. We empirically demonstrate that our approach circumvents the issues associated with multiple comparisons and individual variability while improving the statistics. Moreover, we confirm in control subjects that local responses are robust to distraction whereas global responses depend on attention. We then investigate 104 vegetative state (VS), minimally conscious state (MCS) and conscious state (CS) patients recorded with high-density EEG. For the local response, the proportion of significant decoding scores (M=60\%) does not vary with the state of consciousness. By contrast, for the global response, only 14\% of the VS patients' EEG recordings presented a significant effect, compared to 31\% in MCS patients' and 52\% in CS patients'. In conclusion, single-trial multivariate decoding of novelty responses provides valuable information in non-communicating patients and paves the way towards real-time monitoring of the state of consciousness.}, Doi = {10.1016/j.neuroimage.2013.07.013}, pdf = {http://www.unicog.org/publications/King Dehaene Single-trial decoding of auditory novelty responses Neuroimage 2013.pdf}, Institution = {Cognitive Neuroimaging Unit, Institut National de la Santé et de la Recherche Médicale, U992, F-91191 Gif/Yvette, France; NeuroSpin Center, Institute of BioImaging Commissariat à l'Energie Atomique, F-91191 Gif/Yvette, France; Institut du Cerveau et de la Moelle Epinière Research Center, Institut National de la Santé et de la Recherche Médicale, U975 Paris, France.

At this age, the cortical organization in layers is not completed. Many neurons are still located in the subplate and in the process of migrating to their final location. Nevertheless, we observed several points of similarity with the adult linguistic network. First, whereas syllables elicited larger right than left responses, the posterior temporal region escaped this general pattern, showing faster and more sustained responses over the left than over the right hemisphere. Second, discrimination responses to a change of phoneme (ba vs. ga) and a change of human voice (male vs. female) were already present and involved inferior frontal areas, even in the youngest infants (29-wk gestational age). Third, whereas both types of changes elicited responses in the right frontal region, the left frontal region only reacted to a change of phoneme.

We examined both the activation and the degree of functional lateralization in regions of interest (ROIs) centered on the main activated peaks. Heritability was first investigated by comparing the respective MZ and DZ correlations. Then, genetic and environmental contributions were jointly estimated by fitting a ACE model classically used in twin studies. We found that a subset of the activated network was under genetic influence, encompassing the bilateral posterior superior parietal lobules (PSPL), the right intraparietal sulcus (IPS) and a left superior frontal region. An additional region of the left inferior parietal cortex (IPC), whose deactivation correlated with a behavioral calculation score, also presented higher similarity between MZ than between DZ twins, thus offering a plausible physiological basis for the observable inheritance of math scores.

Given the high temporal resolution of such techniques, scientific questions very often focus on the time-course of an experimental effect. In many studies, researchers focus on a single sensor or the average over a subset of sensors covering a "region of interest" (ROI). However, single-sensor or ROI analyses ignore the fact that the spatial focus of activity is constantly changing, and fail to make full use of the information distributed over the sensor array.We describe a technique that exploits the optimality and simplicity of matched spatial filters in order to reduce experimental effects in multivariate time series data to a single time course. Each (multi-sensor) time sample of each trial is replaced with its projection onto a spatial filter that is matched to an observed experimental effect, estimated from the remaining trials (Effect-Matched Spatial filtering, or EMS filtering). The resulting set of time courses (one per trial) can be used to reveal the temporal evolution of an experimental effect, which distinguishes this approach from techniques that reveal the temporal evolution of an anatomical source or region of interest.We illustrate the technique with data from a dual-task experiment and use it to track the temporal evolution of brain activity during the psychological refractory period. We demonstrate its effectiveness in separating the means of two experimental conditions, and in significantly improving the signal-to-noise ratio at the single-trial level. It is fast to compute and results in readily-interpretable time courses and topographies. The technique can be applied to any data-analysis question that can be posed independently at each sensor, and we provide one example, using linear regression, that highlights the versatility of the technique.The approach described here combines established techniques in a way that strikes a balance between power, simplicity, speed of processing, and interpretability. We have used it to provide a direct view of parallel and serial processes in the human brain that previously could only be measured indirectly.

Increasing literacy also leads to a stronger right-hemispheric lateralization for faces. Here, we evaluated whether this reorganization of the brain's face system has behavioral consequences for the processing of non-linguistic visual stimuli. Three groups of adult illiterates, ex-illiterates and literates were tested with the sequential composite face paradigm that evaluates the automaticity with which faces are processed as wholes. Illiterates were consistently more holistic than participants with reading experience in dealing with faces. A second experiment replicated this effect with both faces and houses.

Literacy related to an increase in fractional anisotropy and a decrease in perpendicular diffusivity in the temporo-parietal portion of the left arcuate fasciculus. The microstructure within this pathway correlated with the reading performance and the degree of functional activation within 2 dominant brain regions involved in reading: The Visual Word Form Area in response to letter strings, and the posterior superior temporal cortex in response to spoken language.

In this perspective, several functional brain imaging tools are currently under development. Bedside cognitive event-related potentials (ERPs) derived from the EEG signal are a good candidate to explore consciousness in these patients because: (1) they have an optimal time resolution within the millisecond range able to monitor the stream of consciousness, (2) they are fully non-invasive and relatively cheap, (3) they can be recorded continuously on dedicated individual systems to monitor consciousness and to communicate with patients, (4) and they can be used to enrich patients' autonomy through brain-computer interfaces. We recently designed an original auditory rule extraction ERP test that evaluates cerebral responses to violations of temporal regularities that are either local in time or global across several seconds. Local violations led to an early response in auditory cortex, independent of attention or the presence of a concurrent visual task, while global violations led to a late and spatially distributed response that was only present when subjects were attentive and aware of the violations. In the present work, we report the results of this test in 65 successive recordings obtained at bedside from 49 non-communicating patients affected with various acute or chronic neurological disorders. At the individual level, we confirm the high specificity of the 'global effect': only conscious patients presented this proposed neural signature of conscious processing.

Preferential and differential tuning of neural populations to these regularities can be demonstrated by assessing rate dependence of neural responses evoked during continuous periodic stimulation. Here, we used functional magnetic resonance imaging to measure regional variations of temporal sensitivity along the human ventral visual stream. By alternating one face and one house stimulus, we combined sufficient low-level signal modulation with changes in semantic meaning and could therefore drive all tiers of visual cortex strongly enough to assess rate dependence. We found several dissociations between early visual cortex and middle- and higher-tier regions. First, there was a progressive slowing down of stimulation rates yielding peak responses along the ventral visual stream. This finding shows the width of temporal integration windows to increase at higher hierarchical levels. Next, for fixed rates, early but not higher visual cortex responses additionally depended on the length of stimulus exposure, which may indicate increased persistence of responses to short stimuli at higher hierarchical levels. Finally, attention, which was recruited by an incidental task, interacted with stimulation rate and shifted tuning peaks toward lower frequencies. Together, these findings quantify neural response properties that are likely to be operational during natural vision and that provide putative neurofunctional substrates of mechanisms that are relevant in several psychophysical phenomena as masking and the attentional blink. Moreover, they illustrate temporal constraints for translating the deployment of attention into enhanced neural responses and thereby account for lower limits of attentional dwell time.}, Doi = {10.1523/JNEUROSCI.2467-12.2012}, pdf = {http://www.unicog.org/publications/14433.full.pdf}, Institution = {Institut National de la Santé et de la Recherche Médicale Unité 992, Saclay, F-91191 Gif-sur-Yvette, France. gauthierb.ens@gmail.com}, Keywords = {Adolescent; Adult; Female; Humans; Male; Photic Stimulation, methods; Psychomotor Performance, physiology; Reaction Time, physiology; Visual Cortex, physiology; Visual Pathways, physiology; Young Adult}, Language = {eng}, Medline-pst = {ppublish}, Owner = {gs985873}, Pii = {32/41/14433}, Pmid = {23055513}, Timestamp = {2013.06.17}, Url = {http://dx.doi.org/10.1523/JNEUROSCI.2467-12.2012} } @Article{Germanaud2012, Title = {Larger is twistier: spectral analysis of gyrification (SPANGY) applied to adult brain size polymorphism.}, Author = {David Germanaud and Julien Lefèvre and Roberto Toro and Clara Fischer and Jessica Dubois and Lucie Hertz-Pannier and Jean-Francois Mangin}, Journal = {Neuroimage}, Year = {2012}, Month = {Nov}, Number = {3}, Pages = {1257--1272}, Volume = {63}, Abstract = {The description of cortical folding pattern (CFP) is challenging because of geometric complexity and inter-subject variability. On a cortical surface mesh, curvature estimation provides a good scalar proxy of CFP. The oscillations of this function can be studied using a Fourier-like analysis to produce a power spectrum representative of the spatial frequency composition of CFP. First, we introduce an original method for the SPectral ANalysis of GYrication (Spangy), which performs a spectral decomposition of the mean curvature of the grey/white interface mesh based on the Laplace-Beltrami operator eigenfunctions. Spangy produces an ordered 7 bands power spectrum of curvature (B0-B6) and provides an anatomically relevant segmentation of CFP based on local spectral composition. A spatial frequency being associated with each eigenfunction, the bandwidth design assumes frequency doubling between consecutive spectral bands. Next, we observed that the last 3 spectral bands (B4, 5 and 6) accounted for 93\% of the analyzed spectral power and were associated with fold-related variations of curvature, whereas the lower frequency bands were related to global brain shape. The spectral segmentation of CFP revealed 1st, 2nd and 3rd order elements associated with B4, B5 and B6 respectively. These elements could be related to developmentally-defined primary, secondary and tertiary folds. Finally, we used allometric scaling of frequency bands power and segmentation to analyze the relationship between the spectral composition of CFP and brain size in a large adult dataset. Total folding power followed a positive allometric scaling which did not divide up proportionally between the bands: B4 contribution was constant, B5 increased like total folding power and B6 much faster. Besides, apparition of new elements of pattern with increasing size only concerned the 3rd order. Hence, we demonstrate that large brains are twistier than smaller ones because of an increased number of high spatial frequency folds, ramifications and kinks that accommodate the allometric increase of cortical surface.}, Doi = {10.1016/j.neuroimage.2012.07.053}, pdf = {http://www.unicog.org/publications/germanaudLefevre_spangyFoldingAnalysis_nimg12.pdf}, Institution = {UMR663, INSERM-Université Paris Descartes, Paris, France. david197@free.fr}, Language = {eng}, Medline-pst = {ppublish}, Owner = {gs985873}, Pii = {S1053-8119(12)00783-5}, Pmid = {22877579}, Timestamp = {2013.06.18}, Url = {http://dx.doi.org/10.1016/j.neuroimage.2012.07.053} } @Article{Hesselmann2012inpress, Title = {Splitting of the P3 component during dual-task processing in a patient with posterior callosal section}, Author = {Hesselmann, G. and Naccache, L. and Cohen, L. and Dehaene, S}, Journal = {Cortex}, Year = {2012}, Volume = {Available online 27 March 2012}, pdf = {http://www.unicog.org/publications/1-s2.0-S0010945212000986-main.pdf}, Owner = {gs985873}, Timestamp = {2012.03.27}, Url = {http://dx.doi.org/10.1016/j.cortex.2012.03.014} } @Article{KatarzynaJednorog.2012, Title = {The Influence of Socioeconomic Status on Children?s Brain Structure}, Author = {Katarzyna Jednorog and Irene Altarelli and Karla Monzalvo and Joel Fluss and Jessica Dubois and Catherine Billard and Ghislaine Dehaene-Lambertz and Franck Ramus}, Journal = {PLoS One}, Year = {2012}, Volume = {August 3, 2012}, pdf = {http://www.unicog.org/publications/Jednorog_PONE-D-11-19850-4.pdf}, Owner = {gs985873}, Timestamp = {2012.08.10} } @Article{Joly2012, Title = {Processing of vocalizations in humans and monkeys: A comparative fMRI study}, Author = {Olivier Joly and Christophe Pallier and Franck Ramus and Daniel Pressnitzer and Wim Vanduffel and and Guy A.

At the first stages of auditory processing, both species showed similar fMRI activity maps within and around the lateral sulcus (the Sylvian fissure in humans). Monkeys showed remarkably similar responses to monkey calls and to human vocal sounds (speech or otherwise), mainly in the lateral sulcus and the adjacent superior temporal gyrus (STG). In contrast, a preference for human vocalizations and especially for speech was observed in the human STG and superior temporal sulcus (STS). The STS and Broca's region were especially responsive to intelligible utterances. The evolution of the language faculty in humans appears to have recruited most of the STS.

Several studies have outlined the neural circuitry involved in generating perceptual inference but only more recently has the individual variability of this inferential process been appreciated. Studies of the interaction of evoked and ongoing neural activity show that inference itself is not merely a stimulus-triggered process but is related to the context of the current brain state into which the processing of external stimulation is embedded. As brain states fluctuate, so does perception of a given sensory input. In multistability, perceptual fluctuation rates are consistent for a given individual but vary considerably between individuals. There has been some evidence for a genetic basis for these individual differences and recent morphometric studies of parietal lobe regions have identified neuroanatomical substrates for individual variability in spontaneous switching behaviour. Moreover, disrupting the function of these latter regions by transcranial magnetic stimulation yields systematic interference effects on switching behaviour, further arguing for a causal role of these regions in perceptual inference.

This is typically the case when seeing and listening to a speaker or when engaged in scene analysis. In such contexts, two mechanisms are needed to single out and build a reliable representation of an event (or object): the temporal parsing of information and the selection of relevant information in the stream. It has previously been shown that rhythmic events naturally build temporal expectations that improve sensory processing at predictable points in time. Here, we asked to which extent temporal regularities can improve the detection and identification of events across sensory modalities. To do so, we used a dynamic visual conjunction search task accompanied by auditory cues synchronized or not with the color change of the target (horizontal or vertical bar). Sounds synchronized with the visual target improved search efficiency for temporal rates below 1.4 Hz but did not affect efficiency above that stimulation rate. Desynchronized auditory cues consistently impaired visual search below 3.3 Hz. Our results are interpreted in the context of the Dynamic Attending Theory: specifically, we suggest that a cognitive operation structures events in time irrespective of the sensory modality of input.

When two tasks have to be performed within a short interval, the second is sharply delayed, an effect called the Psychological Refractory Period (PRP). Similarly, when two successive visual targets are briefly flashed, people may fail to detect the second target (Attentional Blink or AB). Although AB and PRP are typically studied in very different paradigms, a recent detailed neuromimetic model suggests that both might arise from the same serial stage during which stimuli gain access to consciousness and, as a result, can be arbitrarily routed to any other appropriate processor. Here, in agreement with this model, we demonstrate that AB and PRP can be obtained on alternate trials of the same cross-modal paradigm and result from limitations in the same brain mechanisms. We asked participants to respond as fast as possible to an auditory target T1 and then to a visual target T2 embedded in a series of distractors, while brain activity was recorded with magneto-encephalography (MEG). For identical stimuli, we observed a mixture of blinked trials, where T2 was entirely missed, and PRP trials, where T2 processing was delayed. MEG recordings showed that PRP and blinked trials underwent identical sensory processing in visual occipito-temporal cortices, even including the non-conscious separation of targets from distractors. However, late activations in frontal cortex (>350ms), strongly influenced by the speed of task-1 execution, were delayed in PRP trials and absent in blinked trials.

By correlating these two findings, we identify spoken-language predictors of VWFA activation to written words, which differ for dyslexic and normal readers. Similarities in fMRI deficits in both SES groups emphasize the existence of a core set of brain activation anomalies in dyslexia, regardless of culture, language and SES, without however resolving whether these anomalies are a cause or a consequence of impaired reading.}, Doi = {10.1016/j.neuroimage.2012.02.035}, pdf = {http://www.unicog.org/publications/Monzalvo_DyslexicSES_Neuroimg2012.pdf}, Institution = {INSERM, Cognitive Neuroimaging Unit, Gif sur Yvette, 91191 France; CEA, DSV, I2BM, Neurospin center, Gif sur Yvette, 91191 France; University Paris 11, Orsay, France.}, Language = {eng}, Medline-pst = {aheadofprint}, Owner = {gs985873}, Pii = {S1053-8119(12)00212-1}, Pmid = {22387166}, Timestamp = {2012.04.04}, Url = {http://dx.doi.org/10.1016/j.neuroimage.2012.02.035} } @Article{Nakamura2012, Title = {Universal brain systems for recognizing word shapes and handwriting gestures during reading.}, Author = {Kimihiro Nakamura and Wen-Jui Kuo and Felipe Pegado and Laurent Cohen and Ovid J L Tzeng and Stanislas Dehaene}, Journal = {Proc Natl Acad Sci U S A}, Year = {2012}, Month = {Dec}, Number = {50}, Pages = {20762--20767}, Volume = {109}, Abstract = {Do the neural circuits for reading vary across culture? Reading of visually complex writing systems such as Chinese has been proposed to rely on areas outside the classical left-hemisphere network for alphabetic reading. Here, however, we show that, once potential confounds in cross-cultural comparisons are controlled for by presenting handwritten stimuli to both Chinese and French readers, the underlying network for visual word recognition may be more universal than previously suspected. Using functional magnetic resonance imaging in a semantic task with words written in cursive font, we demonstrate that two universal circuits, a shape recognition system (reading by eye) and a gesture recognition system (reading by hand), are similarly activated and show identical patterns of activation and repetition priming in the two language groups. These activations cover most of the brain regions previously associated with culture-specific tuning. Our results point to an extended reading network that invariably comprises the occipitotemporal visual word-form system, which is sensitive to well-formed static letter strings, and a distinct left premotor region, Exner's area, which is sensitive to the forward or backward direction with which cursive letters are dynamically presented.

Mutations of the FOXP2 gene cause a severe form of language impairment and orofacial dyspraxia, while single-nucleotide polymorphisms (SNPs) located within a KIAA0319/TTRAP/THEM2 gene cluster and affecting the KIAA0319 gene expression are associated with reading disability. Neuroimaging studies of clinical populations point to partially distinct cerebral bases for language and reading impairments. However, alteration of FOXP2 and KIAA0319/TTRAP/THEM2 polymorphisms on typically developed language networks has never been explored. Here, we genotyped and scanned 94 healthy subjects using fMRI during a reading task. We studied the correlation of genetic polymorphisms with interindividual variability in brain activation and functional asymmetry in frontal and temporal cortices. In FOXP2, SNPs rs6980093 and rs7799109 were associated with variations of activation in the left frontal cortex. In the KIAA0319/TTRAP/THEM2 locus, rs17243157 was associated with asymmetry in functional activation of the superior temporal sulcus (STS). Interestingly, healthy subjects bearing the KIAA0319/TTRAP/THEM2 variants previously identified as enhancing the risk of dyslexia showed a reduced left-hemispheric asymmetry of the STS. Our results confirm that both FOXP2 and KIAA0319/TTRAP/THEM2 genes play an important role in human language development, but probably through different cerebral pathways.

Specifically, we investigated whether, similar to language, an expression has to be scanned sequentially while the nested syntactic structure is being computed or, alternatively, whether this structure can be extracted quickly and in parallel. Our data provide evidence for the latter: fixations sequences were stereotypically organized in clusters that reflected a fast identification of syntactic embeddings. A syntactically relevant pattern of eye movement was observed even when syntax was defined by implicit procedural rules (precedence of multiplication over addition) rather than explicit parentheses. While the total number of fixations was determined by syntax, the duration of each fixation varied with the complexity of the arithmetic operation at each step.

To build testable working hypotheses, investigators thus rely on analysis of previous work, sometimes formalized in a so-called meta-analysis. In brain imaging, this approach underlies the specification of regions of interest (ROIs) that are usually selected on the basis of the coordinates of previously detected effects. In this paper, we propose to use a database of images, rather than coordinates, and frame the problem as transfer learning: learning a discriminant model on a reference task to apply it to a different but related new task. To facilitate statistical analysis of small cohorts, we use a sparse discriminant model that selects predictive voxels on the reference task and thus provides a principled procedure to define ROIs. The benefits of our approach are twofold. First it uses the reference database for prediction, i.e., to provide potential biomarkers in a clinical setting. Second it increases statistical power on the new task. We demonstrate on a set of 18 pairs of functional MRI experimental conditions that our approach gives good prediction. In addition, on a specific transfer situation involving different scanners at different locations, we show that voxel selection based on transfer learning leads to higher detection power on small cohorts.}, Institution = {Parietal Team, INRIA Saclay-Ile-de-France, Saclay, France. yannick.schwartz@inria.fr}, Keywords = {Algorithms; Brain Mapping; Brain, physiology; Databases, Factual; Humans; Image Enhancement, methods; Image Interpretation, Computer-Assisted, methods; Information Storage and Retrieval; Magnetic Resonance Imaging, methods; Meta-Analysis as Topic; Pattern Recognition, Automated, methods; Reproducibility of Results; Sensitivity and Specificity}, Language = {eng}, Medline-pst = {ppublish}, Owner = {gs985873}, Pmid = {23286137}, Timestamp = {2015.05.26} } @Article{Sebastian-Galles2012, Title = {Neuroanatomical markers of individual differences in native and non-native vowel perception}, Author = {Sebastian-Galles, N and Soriano-Mas, C. and Baus, C. and Diaz, B. and Ressel ,V. and Christophe Pallier and Costa, A. and Pujol, J,}, Journal = {Journal of Neurolinguistics}, Year = {2012}, Pages = {150-62}, Volume = {25}, pdf = {http://www.unicog.org/publications/Sebastian_Galles2012.pdf}, Owner = {gs985873}, Timestamp = {2012.07.03} } @Article{Striem-Amit2012, Title = {Reading with sounds: sensory substitution selectively activates the visual word form area in the blind}, Author = {Striem-Amit, Ella and Cohen, Laurent and Dehaene, Stanislas and Amedi, Amir}, Journal = {Neuron}, Year = {2012}, Month = {Nov}, Number = {3}, Pages = {640--652}, Volume = {76}, Abstract = {Using a visual-to-auditory sensory-substitution algorithm, congenitally fully blind adults were taught to read and recognize complex images using "soundscapes"--sounds topographically representing images. fMRI was used to examine key questions regarding the visual word form area (VWFA): its selectivity for letters over other visual categories without visual experience, its feature tolerance for reading in a novel sensory modality, and its plasticity for scripts learned in adulthood. The blind activated the VWFA specifically and selectively during the processing of letter soundscapes relative to both textures and visually complex object categories and relative to mental imagery and semantic-content controls. Further, VWFA recruitment for reading soundscapes emerged after 2 hr of training in a blind adult on a novel script.

Stimuli consisted of a closed egg-shaped contour made of disconnected Gabor patches, within a background of randomly oriented Gabor stimuli. Subjects had to decide whether the egg was pointing left or right. Difficulty was varied by jittering the orientation of the Gabor patches forming the contour. Contour integration performance was lower in illiterates than in both ex-illiterate and literate controls.

How does the brain cope with speeded language? And what processing bottlenecks eventually make language incomprehensible above a certain presentation rate? We used time-resolved fMRI to probe the brain responses to spoken and written sentences presented at five compression rates, ranging from intelligible (60-100\% of the natural duration) to challenging (40\%) and unintelligible (20\%). The results show that cortical areas differ sharply in their activation speed and amplitude. In modality-specific sensory areas, activation varies linearly with stimulus duration. However, a large modality-independent left-hemispheric language network, including the inferior frontal gyrus (pars orbitalis and triangularis) and the superior temporal sulcus, shows a remarkably time-invariant response, followed by a sudden collapse for unintelligible stimuli. Finally, linear and nonlinear responses, reflecting a greater effort as compression increases, are seen at various prefrontal and parietal sites. We show that these profiles fit with a simple model according to which the higher stages of language processing operate at a fixed speed and thus impose a temporal bottleneck on sentence comprehension. At presentation rates faster than this internal processing speed, incoming words must be buffered, and intelligibility vanishes when buffer storage and retrieval operations are saturated. Based on their temporal and amplitude profiles, buffer regions can be identified with the left inferior frontal/anterior insula, precentral cortex, and mesial frontal cortex.}, Doi = {10.1523/JNEUROSCI.5685-11.2012}, pdf = {http://www.unicog.org/publications/VagharchakianDehaeneLambertPallierDehaene_TemporalBottleneckLanguage_JNeurosci2012.pdf}, Institution = {Institut National de la Santé et de la Recherche Médicale, Cognitive Neuroimaging Unit, F91191 Gif-sur-Yvette, France, Commissariat à L'Energie Atomique et aux Energies Alternatives, NeuroSpin Center, F91191 Gif-sur-Yvette, France, Université Paris XI, 91405 Orsay, France, and Collège de France, 75231 Paris, France.}, Language = {eng}, Medline-pst = {ppublish}, Owner = {gs985873}, Pii = {32/26/9089}, Pmid = {22745508}, Timestamp = {2012.07.03}, Url = {http://dx.doi.org/10.1523/JNEUROSCI.5685-11.2012} } @Article{Wassenhove2012, Title = {From the dynamic structure of the brain to the emergence of time experiences}, Author = {van Wassenhove, Virginie}, Journal = {Kronoscope}, Year = {2012}, Pages = {201-218}, Volume = {12(2)}, pdf = {http://www.unicog.org/publications/2012_vvw_Kronoscope.pdf}, Owner = {gs985873}, Timestamp = {2013.09.09} } @Article{Wacongne2012, Title = {A neuronal model of predictive coding accounting for the mismatch negativity.}, Author = {Catherine Wacongne and Jean-Pierre Changeux and Stanislas Dehaene}, Journal = {J Neurosci}, Year = {2012}, Month = {Mar}, Number = {11}, Pages = {3665--3678}, Volume = {32}, Abstract = {The mismatch negativity (MMN) is thought to index the activation of specialized neural networks for active prediction and deviance detection. However, a detailed neuronal model of the neurobiological mechanisms underlying the MMN is still lacking, and its computational foundations remain debated. We propose here a detailed neuronal model of auditory cortex, based on predictive coding, that accounts for the critical features of MMN. The model is entirely composed of spiking excitatory and inhibitory neurons interconnected in a layered cortical architecture with distinct input, predictive, and prediction error units. A spike-timing dependent learning rule, relying upon NMDA receptor synaptic transmission, allows the network to adjust its internal predictions and use a memory of the recent past inputs to anticipate on future stimuli based on transition statistics. We demonstrate that this simple architecture can account for the major empirical properties of the MMN. These include a frequency-dependent response to rare deviants, a response to unexpected repeats in alternating sequences (ABABAA?), a lack of consideration of the global sequence context, a response to sound omission, and a sensitivity of the MMN to NMDA receptor antagonists.

In adults, category-based specializations manifest as greater neural responses in visual regions of the brain (e.g., fusiform gyrus) to some categories over others. However, few studies have examined how these specializations originate in the brains of children. Moreover, it is as yet unknown whether the development of visual specializations hinges on "increases" in the response to the preferred categories, "decreases" in the responses to nonpreferred categories, or "both." This question is relevant to a long-standing debate concerning whether neural development is driven by building up or pruning back representations. To explore these questions, we measured patterns of visual activity in 4-year-old children for 4 categories (faces, letters, numbers, and shoes) using functional magnetic resonance imaging. We report 2 key findings regarding the development of visual categories in the brain: 1) the categories "faces" and "symbols" doubly dissociate in the fusiform gyrus before children can read and 2) the development of category-specific responses in young children depends on cortical responses to nonpreferred categories that decrease as preferred category knowledge is acquired.}, Doi = {10.1093/cercor/bhq078}, pdf = {http://www.unicog.org/publications/Cereb.

Here, we extended these investigations into the domain of cognitive control. Using functional neuroimaging and a sparse event-related design (with long and unpredictable intervals), we measured ongoing activity fluctuations and evoked responses in volunteers performing a Stroop task with color-word interference. Across trials, prestimulus activity of several regions predicted subsequent response speed and across subjects this effect scaled with the Stroop effect size, being significant only in subjects manifesting behavioral interference. These effects occurred only in task relevant as the dorsal anterior cingulate and dorsolateral prefrontal cortex as well as ventral visual areas sensitive to color and visual words. Crucially, in subjects showing a Stroop effect, reaction times were faster when prestimulus activity was higher in task-relevant (color) regions and slower when activity was higher in irrelevant (word form) regions. These findings suggest that intrinsic brain activity fluctuations modulate neural mechanisms underpinning selective voluntary attention and cognitive control.

Here we ask a simple question: How is the accumulation of evidence affected by the level of awareness of the information? We examined the influence of awareness on decision-making using combined behavioral methods and magneto-encephalography (MEG). Participants were required to make decisions by accumulating evidence over a series of visually presented arrow stimuli whose visibility was modulated by masking. Behavioral results showed that participants could accumulate evidence under both high and low visibility. However, a top-down strategic modulation of the flow of incoming evidence was only present for stimuli with high visibility: once enough evidence had been accrued, participants strategically reduced the impact of new incoming stimuli. Also, decision-making speed and confidence were strongly modulated by the strength of the evidence for high-visible but not low-visible evidence, even though direct priming effects were identical for both types of stimuli. Neural recordings revealed that, while initial perceptual processing was independent of visibility, there was stronger top-down amplification for stimuli with high visibility than low visibility. Furthermore, neural markers of evidence accumulation over occipito-parietal cortex showed a strategic bias only for highly visible sensory information, speeding up processing and reducing neural computations related to the decision process. Our results indicate that the level of awareness of information changes decision-making: while accumulation of evidence already exists under low visibility conditions, high visibility allows evidence to be accumulated up to a higher level, leading to important strategical top-down changes in decision-making. Our results therefore suggest a potential role of awareness in deploying flexible strategies for biasing information acquisition in line with one's expectations and goals.}, Doi = {10.1371/journal.pbio.1001203}, pdf = {http://www.unicog.org/publications/deLange_vanGaal_Lamme_Dehaene_PLOS_Biology_How awareness changes the relative weights of evidence during human decision-making (2011).pdf}, Institution = {Donders Institute for Brain, Cognition and Behavior, Radboud University Nijmegen, Nijmegen, the Netherlands.}, Language = {eng}, Medline-pst = {ppublish}, Owner = {gs985873}, Pii = {PBIOLOGY-D-11-02037}, Pmid = {22131904}, Timestamp = {2011.12.07}, Url = {http://dx.doi.org/10.1371/journal.pbio.1001203} } @Article{Dehaene2011b, Title = {Experimental and theoretical approaches to conscious processing.}, Author = {Stanislas Dehaene and Jean-Pierre Changeux}, Journal = {Neuron}, Year = {2011}, Month = {Apr}, Number = {2}, Pages = {200--227}, Volume = {70}, Abstract = {Recent experimental studies and theoretical models have begun to address the challenge of establishing a causal link between subjective conscious experience and measurable neuronal activity. The present review focuses on the well-delimited issue of how an external or internal piece of information goes beyond nonconscious processing and gains access to conscious processing, a transition characterized by the existence of a reportable subjective experience. Converging neuroimaging and neurophysiological data, acquired during minimal experimental contrasts between conscious and nonconscious processing, point to objective neural measures of conscious access: late amplification of relevant sensory activity, long-distance cortico-cortical synchronization at beta and gamma frequencies, and "ignition" of a large-scale prefronto-parietal network. We compare these findings to current theoretical models of conscious processing, including the Global Neuronal Workspace (GNW) model according to which conscious access occurs when incoming information is made globally available to multiple brain systems through a network of neurons with long-range axons densely distributed in prefrontal, parieto-temporal, and cingulate cortices.

Our results show four significant asymmetries. First and foremost, they stress an important but little-known asymmetry: the larger depth of the right superior temporal sulcus (STS) at the base of Heschl's gyrus. Then, we characterized the early forward and upward shift of the posterior end of the right Sylvian fissure, the elongation of the left planum temporale as well as the thickening of the left Heschl's gyrus. The rightward bias of the STS is robust and large, and is not correlated with the leftward asymmetries of the planum and Heschl's gyrus, suggesting that different morphogenetic factors drive these asymmetries. As this sulcus is engaged in multiple high-level functions (e.g. language and theory of mind), and has been spotted as abnormal in several developmental disorders (e.g. schizophrenia, autism), this early rightward asymmetry should be further explored as a target for a genetic evolutionary pressure.}, Doi = {10.1016/j.neuroimage.2011.06.016}, pdf = {http://www.unicog.org/publications/Glasel_STS_asym_NI11.pdf}, Institution = {INSERM, U992, Neurospin, 91191 Gif/Yvette, France, Université Paris 11, Paris, France; IFR49, Neurospin, 91191 Gif/Yvette, France.}, Language = {eng}, Medline-pst = {ppublish}, Owner = {gs985873}, Pii = {S1053-8119(11)00624-0}, Pmid = {21723397}, Timestamp = {2011.09.21}, Url = {http://dx.doi.org/10.1016/j.neuroimage.2011.06.016} } @Article{Hesselmann2011, Title = {Probing the cortical network underlying the psychological refractory period: A combined EEG-fMRI study}, Author = {G.

In the psychological refractory period (PRP) paradigm, where two tasks have to be performed in brief succession, central processing of the second task is delayed when the two tasks are performed at short time intervals. Here, we aimed to probe the cortical network underlying this postponement of central processing by simultaneously recording electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) data while 12 subjects performed two simple number-comparison tasks. Behavioral data showed a significant slowing of response times to the second target stimulus at short stimulus-onset asynchronies, together with significant correlations between response times to the first and second target stimulus, i.e., the hallmarks of the PRP effect. The analysis of EEG data showed a significant delay of the post-perceptual P3 component evoked by the second target, which was of similar magnitude as the effect on response times. fMRI data revealed an involvement of parietal and prefrontal regions in dual-task processing. The combined analysis of fMRI and EEG data-based on the trial-by-trial variability of the P3-revealed that BOLD signals in two bilateral regions in the inferior parietal lobe and precentral gyrus significantly covaried with P3 related activity. Our results show that combining neuroimaging methods of high spatial and temporal resolutions can help to identify cortical regions underlying the central bottleneck of information processing, and strengthen the conclusion that fronto-parietal cortical regions participate in a distributed "global neuronal workspace" system that underlies the generation of the P3 component and may be one of the key cerebral underpinnings of the PRP bottleneck.}, Doi = {10.1016/j.neuroimage.2011.03.017}, pdf = {http://www.unicog.org/publications/1-s2.0-S105381191100276X-main.pdf}, Institution = {Department of Neurobiology, Weizmann Institute of Science, Rehovot, Israel.}, Language = {eng}, Medline-pst = {aheadofprint}, Owner = {gs985873}, Pii = {S1053-8119(11)00276-X}, Pmid = {21397701}, Timestamp = {2011.04.13}, Url = {http://dx.doi.org/10.1016/j.neuroimage.2011.03.017} } @Article{Izard2011, Title = {Flexible intuitions of Euclidean geometry in an Amazonian indigene group.}, Author = {Véronique Izard and Pierre Pica and Elizabeth S Spelke and Stanislas Dehaenee}, Journal = {Proc Natl Acad Sci U S A}, Year = {2011}, Month = {May}, Abstract = {Kant argued that Euclidean geometry is synthesized on the basis of an a priori intuition of space.

Our tests probed intuitions of points, lines, and surfaces in participants from an indigene group in the Amazon, the Mundurucu, as well as adults and age-matched children controls from the United States and France and younger US children without education in geometry. The responses of Mundurucu adults and children converged with that of mathematically educated adults and children and revealed an intuitive understanding of essential properties of Euclidean geometry. For instance, on a surface described to them as perfectly planar, the Mundurucu's estimations of the internal angles of triangles added up to ?180 degrees, and when asked explicitly, they stated that there exists one single parallel line to any given line through a given point. These intuitions were also partially in place in the group of younger US participants.

As fiber crossing is prominent in the cerebral white matter, the authors propose an extension to the subcortical disconnection framework that opens the door to ascribing a more diversified clinical phenomenology to white matter damage and ensuing disconnection than has been the case so far.}, Doi = {10.1177/1073858411402093}, Institution = {INSERM, Unité 992, and NeuroSpin, I2BM, DSV, CEA, Gif-sur-Yvette, France.}, Language = {eng}, Medline-pst = {aheadofprint}, Owner = {gs985873}, Pii = {1073858411402093}, Pmid = {21670425}, Timestamp = {2011.11.29}, Url = {http://dx.doi.org/10.1177/1073858411402093} } @Article{Leroy2011, Title = {Early Maturation of the Linguistic Dorsal Pathway in Human Infants.}, Author = {François Leroy and Hervé Glasel and Jessica Dubois and Lucie Hertz-Pannier and Bertrand Thirion and Jean-François Mangin and Ghislaine Dehaene-Lambertz}, Journal = {J Neurosci}, Year = {2011}, Month = {Jan}, Number = {4}, Pages = {1500--1506}, Volume = {31}, Abstract = {Human infants, unlike even closely related primates, exhibit a remarkable capacity for language learning.

This view has favored a description of learning based on bottom-up algorithms and has tended to discard the role of frontal regions, which were assumed to be barely functional early on. Here, using an index based on the normalized T2-weighted magnetic resonance signal, we have quantified maturation within the linguistic network in fourteen 1- to 4-month-old infants. Our results show first that the ventral superior temporal sulcus (STS), and not the inferior frontal area, is the less mature perisylvian region. A significant difference of maturation in the STS favoring the right side is an early testimony of the distinctive left-right development of this structure observed during the whole life. Second, asymmetries of maturation in Broca's area were correlated with asymmetries in the posterior STS and in the parietal segment of the arcuate fasciculus, suggesting that an efficient frontotemporal dorsal pathway might provide infants with a phonological loop circuitry much earlier than expected.}, Doi = {10.1523/JNEUROSCI.4141-10.2011}, pdf = {http://www.unicog.org/publications/leroy_infant_ling_dorsal_path_matur_JoN11.pdf}, Institution = {INSERM, U992, Neurospin, 91191 Gif/Yvette, France, Université Paris 11, 91405 Orsay, France, IFR49, Neurospin, 91191 Gif/Yvette, France, INSERM, U663, 75015 Paris, France, Université Paris 5, 75015 Paris, France, Commissariat à l'Energie Atomique (CEA), Laboratoire de Recherche Biomédicale, NeuroSpin, 91191 Gif-sur-Yvette, France, INRIA, Saclay-Ile-de-France, Parietal Project team, 91191 Gif-sur-Yvette, France, and CEA, Laboratoire de Neuroimagerie Assistée par Ordinateur, NeuroSpin, 91191 Gif-sur-Yvette, France.}, Language = {eng}, Medline-pst = {ppublish}, Owner = {gs985873}, Pii = {31/4/1500}, Pmid = {21273434}, Timestamp = {2011.02.03}, Url = {http://dx.doi.org/10.1523/JNEUROSCI.4141-10.2011} } @Article{Leroy2011a, Title = {Atlas-Free Surface Reconstruction of the Cortical Grey-White Interface in Infants}, Author = {Francois Leroy and JF Mangin and François Rousseau and Hervé Glasel and L.

This analysis framework disregards some important principles of brain organization: population coding, distributed and overlapping representations. Multivariate pattern analysis, i.e., the prediction of behavioral variables from brain activation patterns better captures this structure. To cope with the high dimensionality of the data, the learning method has to be regularized. However, the spatial structure of the image is not taken into account in standard regularization methods, so that the extracted features are often hard to interpret. More informative and interpretable results can be obtained with the l(1) norm of the image gradient, also known as its total variation (TV), as regularization.

We therefore searched for brain regions where activation increased parametrically with the size of linguistic constituents, in response to a visual stream always comprising 12 written words or pseudowords. The results isolated a network of left-hemispheric regions that could be dissociated into two major subsets. Inferior frontal and posterior temporal regions showed constituent size effects regardless of whether actual content words were present or were replaced by pseudowords (jabberwocky stimuli). This observation suggests that these areas operate autonomously of other language areas and can extract abstract syntactic frames based on function words and morphological information alone.

In the blind, comparable reading expertise can be achieved using Braille. This study investigated which area plays the role of the VWFA in the blind. One would expect this area to be at either parietal or bilateral occipital cortex, reflecting the tactile nature of the task and crossmodal plasticity, respectively [7, 8]. However, according to the metamodal theory [9], which suggests that brain areas are responsive to a specific representation or computation regardless of their input sensory modality, we predicted recruitment of the left-hemispheric VWFA, identically to the sighted. Using functional magnetic resonance imaging, we show that activation during Braille reading in blind individuals peaks in the VWFA, with striking anatomical consistency within and between blind and sighted.

Greater responses to written words than to objects were found not only in the VWFA, but also in areas V1/V2 and V3v/V4.

Subjective time dilation was observed for the looming stimulus but not for the receding one, which was estimated to be of equal duration to the standards. The neural activation for targets (looming and receding) contrasted with the standards revealed an increased activation of the anterior insula and of the anterior cingulate cortex. Contrasting the looming with the receding targets (i.e., capturing the time dilation effect proper) revealed a specific activation of cortical midline structures.

Responses to auditory mismatches and omissions are interpreted as reflecting the prediction error when these predictions are violated. An alternative interpretation, however, is that neurons passively adapt to repeated stimuli. We separated these alternative interpretations by designing a hierarchical auditory novelty paradigm and recording human EEG and magnetoencephalographic (MEG) responses to mismatching or omitted stimuli. In the crucial condition, participants listened to frequent series of four identical tones followed by a fifth different tone, which generates a mismatch response. Because this response itself is frequent and expected, the hierarchical predictive coding hypothesis suggests that it should be cancelled out by a higher-order prediction. Three consequences ensue. First, the mismatch response should be larger when it is unexpected than when it is expected. Second, a perfectly monotonic sequence of five identical tones should now elicit a higher-order novelty response. Third, omitting the fifth tone should reveal the brain's hierarchical predictions. The rationale here is that, when a deviant tone is expected, its omission represents a violation of two expectations: a local prediction of a tone plus a hierarchically higher expectation of its deviancy.

However, much less is known about how sequentially presented evidence is integrated over time for successful decision making. The aim of this study was to study the mechanisms of sequential decision making in humans. In a magnetoencephalography (MEG) study, we presented healthy volunteers with sequences of centrally presented arrows. Sequence length varied between one and five arrows, and the accumulated directions of the arrows informed the subject about which hand to use for a button press at the end of the sequence (e.g., LRLRR should result in a right-hand press). Mathematical modeling suggested that nonlinear accumulation was the rational strategy for performing this task in the presence of no or little noise, whereas quasilinear accumulation was optimal in the presence of substantial noise. MEG recordings showed a correlate of evidence integration over parietal and central cortex that was inversely related to the amount of accumulated evidence (i.e., when more evidence was accumulated, neural activity for new stimuli was attenuated). This modulation of activity likely reflects a top-down influence on sensory processing, effectively constraining the influence of sensory information on the decision variable over time. The results indicate that, when making decisions on the basis of sequential information, the human nervous system integrates evidence in a nonlinear manner, using the amount of previously accumulated information to constrain the accumulation of additional evidence.}, Doi = {10.1523/JNEUROSCI.4080-09.2010}, pdf = {http://www.unicog.org/publications/DeLange_SDehaene_JNeur2010.pdf}, Institution = {Donders Institute for Brain, Cognition and Behaviour, Radboud University, 6525 EN Nijmegen, The Netherlands. florisdelange@gmail.com}, Keywords = {Adult; Automatic Data Processing; Brain Mapping; Decision Making, physiology; Female; Humans; Magnetoencephalography, methods; Male; Models, Biological; Models, Theoretical; Neuronal Plasticity, physiology; Pattern Recognition, Visual, physiology; Photic Stimulation, methods; Psychomotor Performance, physiology; Reaction Time, physiology; Serial Learning, physiology; Time Factors; Young Adult}, Owner = {gs985873}, Pii = {30/2/731}, Pmid = {20071538}, Timestamp = {2010.02.05}, Url = {http://dx.doi.org/10.1523/JNEUROSCI.4080-09.2010} } @Article{Dehaene2010inpress, Title = {Space, time,and number: a Kantian research program}, Author = {Dehaene, S and Brannon, EM}, Journal = {trends in cognitive neurosciences}, Year = {2010}, Pages = {517-19}, Volume = {14}, pdf = {http://www.unicog.org/publications/TICS_923_final.pdf}, Owner = {gs985873}, Timestamp = {2010.11.17} } @Article{Dehaene2010, Title = {Why do children make mirror errors in reading?

Our earlier research demonstrated that an adult-like left-lateralized network of perisylvian areas is already active when infants listen to sentences in their native language, but did not address the issue of the specialization of this network for speech processing. Here we used fMRI to study the organization of brain activity in two-month-old infants when listening to speech or to music. We also explored how infants react to their mother's voice relative to an unknown voice. The results indicate that the well-known structural asymmetry already present in the infants' posterior temporal areas has a functional counterpart: there is a left-hemisphere advantage for speech relative to music at the level of the planum temporale. The posterior temporal regions are thus differently sensitive to the auditory environment very early on, channelling speech inputs preferentially to the left side. Furthermore, when listening to the mother's voice, activation was modulated in several areas, including areas involved in emotional processing (amygdala, orbito-frontal cortex), but also, crucially, a large extent of the left posterior temporal lobe, suggesting that the mother's voice plays a special role in the early shaping of posterior language areas.

Recently, magnetic resonance imaging (MRI) and dedicated post-processing tools enabled the quantitative study of brain development non-invasively in the preterm newborn. However, previous investigations were conducted either over the whole brain or in specific sulci. These approaches may consequently fail to highlight most cerebral sites, where anatomical landmarks are hard to delineate among individuals. In this cross-sectional study, we aimed to blindly and automatically map early asymmetries over the immature cortex. Voxel-based analyses of cortical and white matter masks were performed over a group of 25 newborns from 26 to 36weeks of gestational age. Inter-individual variations associated with increasing age were first detected in large cerebral regions, with a prevalence of the right hemisphere in comparison with the left. Asymmetries were further highlighted in three specific cortical regions. Confirming previous studies, we observed deeper STS on the right side and larger posterior region of the sylvian fissure on the left side, close to planum temporale. For the first time, we also detected larger anterior region of the sylvian fissure on the left side, close to Broca's region. This study demonstrated that perisylvian regions are the only regions to be asymmetric from early on, suggesting their anatomical specificity for the emergence of functional lateralization in language processing prior to language exposure.}, Doi = {10.1016/j.neuroimage.2010.03.054}, pdf = {http://www.unicog.org/publications/duboisHuppi_asymmetriesPreterm_neuroimage10.pdf}, Institution = {Paris, France.}, Language = {eng}, Medline-pst = {aheadofprint}, Owner = {gs985873}, Pii = {S1053-8119(10)00341-1}, Pmid = {20362679}, Timestamp = {2010.05.12}, Url = {http://dx.doi.org/10.1016/j.neuroimage.2010.03.054} } @Article{Forget2009, Title = {Temporal Integration in Visual Word Recognition.}, Author = {Joachim Forget and Marco Buiatti and Stanislas Dehaene}, Journal = {J Cogn Neurosci}, Year = {2010}, Pages = {1054-68}, Volume = {22}, Abstract = {Abstract When two displays are presented in close temporal succession at the same location, how does the brain assign them to one versus two conscious percepts? We investigate this issue using a novel reading paradigm in which the odd and even letters of a string are presented alternatively at a variable rate. The results reveal a window of temporal integration during reading, with a nonlinear boundary around approximately 80 msec of presentation duration. Below this limit, the oscillating stimulus is easily fused into a single percept, with all characteristics of normal reading. Above this limit, reading times are severely slowed and suffer from a word-length effect. ERPs indicate that, even at the fastest frequency, the oscillating stimulus elicits synchronous oscillations in posterior visual cortices, while late ERP components sensitive to lexical status vanish above the fusion threshold. Thus, the fusion/segregation dilemma is not resolved by retinal or subcortical filtering, but at cortical level by at most 300 msec.

It is characterized by errors of letter migration within words, such as reading trail as trial and form as from. In order to examine whether LPD is domain-specific, and to assess the domain-specificity of the visual analysis system, this study explored whether LPD extends to number reading, by testing whether individuals who have letter migrations in word reading also show migrations while reading numbers. The reading of words and numbers of 12 Hebrew-speaking individuals with developmental LPD was assessed. Experiment 1 tested reading aloud of words and numbers, and Experiment 2 tested same-different decisions in words and numbers. The findings indicated that whereas the participants with developmental LPD showed a large number of migration errors in reading words, 10 of them read numbers well, without migration errors, and not differently from the control participants. A closer inspection of the pattern of errors in words and numbers of two individuals who had migrations in both numbers and words showed qualitative differences in the characteristics of migration errors in the two types of stimuli. In word reading, migration errors appeared predominantly in middle letters, whereas the errors in numbers occurred mainly in final (rightmost) digits. Migrations in numbers occurred almost exclusively in adjacent digits, but in words migrations occurred both in adjacent and in nonadjacent letters. The results thus indicate that words can be selectively impaired, without a parallel impairment in numbers, and that even when numbers are also impaired they show different error pattern. Thus, the visual analyzer is actually an orthographic visual analyzer, a module that is domain-specific for the analysis of words.}, Doi = {10.1016/j.cortex.2009.08.007}, pdf = {http://www.unicog.org/publications/1-s2.0-S0010945209002494-main.pdf}, Institution = {Language and Brain Lab, School of Education, Tel Aviv University, Israel. naamafr@post.tau.ac.il}, Keywords = {Adolescent; Adult; Dyslexia, physiopathology/psychology; Female; Humans; Male; Mathematics; Neuropsychological Tests; Pattern Recognition, Visual; Reading; Semantics}, Language = {eng}, Medline-pst = {ppublish}, Owner = {gs985873}, Pii = {S0010-9452(09)00249-4}, Pmid = {19853849}, Timestamp = {2014.01.21}, Url = {http://dx.doi.org/10.1016/j.cortex.2009.08.007} } @Article{Giersch2010, Title = {Visuo-perceptual organization and working memory in patients with schizophrenia.}, Author = {Anne Giersch and Mitsouko van Assche and Caroline Huron and David Luck}, Journal = {Neuropsychologia}, Year = {2010}, Month = {Dec}, Abstract = {We explore the mechanisms sub-tending the re-organization and memorization of visual information by studying how these mechanisms fail in patients with schizophrenia. Several studies have suggested that patients have difficulties in organizing information in perception and memory. We explore to what extent prompting patients to group items influences memory performance. We distinguish automatic grouping from top-down grouping processes, which are especially involved in re-organizing information. The main task was to memorize pairs of figures. Following manipulation of proximity, pairs of figures were part of the same perceptual group (within-group pair, formed on the basis of automatic grouping) or belonged to different groups (between-group pairs, re-grouped through top-down processes). Prior to the memory task, subjects ran a perception task prompting them to prioritize either within-group or between-group pairs. Unlike patients, controls globally benefited from grouping by proximity in the memory task. In addition, the results showed that prioritizing between-group pairs had a deleterious effect in patients, but with a large decrement in memory performance in the case of within-group rather than between-group figures. This occurred despite preserved focalization on within-group figures, as shown by eye-movement recordings. The suggestion is that when patients are prompted to re-group separate items, they can do so, but the benefit derived from automatic grouping is then not only lost but also reversed. This suggests re-organizing visual information not only involves re-grouping separate items but also integrating these new groups in a unified representation, which is impaired in patients with schizophrenia.}, Doi = {10.1016/j.neuropsychologia.2010.12.016}, pdf = {http://www.unicog.org/publications/Giersch_2010_Neurosphychologia.pdf}, Institution = {INSERM U666, Centre Hospitalier Régional de Strasbourg, Dept. of Psychiatry I, Hôpital Civil, 1, place de l'Hôpital, F-67091 Strasbourg Cedex, France.}, Language = {eng}, Medline-pst = {aheadofprint}, Owner = {gs985873}, Pii = {S0028-3932(10)00549-X}, Pmid = {21167849}, Timestamp = {2011.02.02}, Url = {http://dx.doi.org/10.1016/j.neuropsychologia.2010.12.016} } @Article{Grillon2010, Title = {Episodic memory and impairment of an early encoding process in schizophrenia.}, Author = {Marie-Laure Grillon and Marie-Odile Krebs and Raphaël Gourevitch and Anne Giersch and Caroline Huron}, Journal = {Neuropsychology}, Year = {2010}, Month = {Jan}, Number = {1}, Pages = {101--108}, Volume = {24}, Abstract = {Investigations of memory impairment in schizophrenia have frequently revealed a strategic processing deficit at encoding.

According to this claim, functional magnetic resonance imaging (fMRI) would pick up not only signals that reflect electrical brain activity but also purely hemodynamic signals that are not linked to neural activity. Here, we show that that study's failure to obtain significant electrophysiological responses to task structure is easily understood on the basis of findings reported for related functional paradigms. Ironically and counter its intention, the study by Sirotin and Das reminds us of the exquisite sensitivity of spatially pooled hemodynamic signals and the limitations of recording only very local samples of electrical activity by microelectrodes. We suggest that this sensitivity of hemodynamic signals should be converted into spatial resolution. In other words, hemodynamic signals should be used to create maps.

Trial-by-trial variance of eye movement is always observed within an identical experimental condition. This has often been treated as experimental error without addressing its significance. The present study examined statistical linkages between the two eyes' movements, namely interocular yoking, for the variance of eye position and velocity. METHODS : Horizontal saccadic movements were recorded from twelve right-eye-dominant subjects while they decided on saccade direction in Go-Only sessions and on both saccade execution and direction in Go/NoGo sessions. We used infrared corneal reflection to record simultaneously and independently the movement of each eye. Quantitative measures of yoking were provided by mutual information analysis of eye position or velocity, which is sensitive to both linear and non-linear relationships between the eyes' movements. Our mutual information analysis relied on the variance of the eyes movements in each experimental condition. The range of movements for each eye varies for different conditions so yoking was further studied by comparing GO-Only vs. Go/NoGo sessions, leftward vs. rightward saccades. RESULTS : Mutual information analysis showed that velocity yoking preceded positional yoking. Cognitive load increased trial variances of velocity with no increase in velocity yoking, suggesting that cognitive load may alter neural processes in areas to which oculomotor control is not tightly linked. The comparison between experimental conditions showed that interocular linkage in velocity variance of the right eye lagged that of the left eye during saccades. CONCLUSIONS : We conclude quantitative measure of interocular yoking based on trial-to-trial variance within a condition, as well as variance between conditions, provides a powerful tool for studying the binocular movement mechanism.}, Doi = {10.1186/1753-4631-4-S1-S10}, pdf = {http://www.unicog.org/publications/Maruyama_NLBMP2010 (2).pdf}, Institution = {Laboratory for Human Brain Dynamics, RIKEN Brain Science Institute, 2-1 Hirosawa, Wakoshi, Saitama 351-0198, Japan . mmasaki1974@gmail.com.}, Language = {eng}, Medline-pst = {epublish}, Owner = {gs985873}, Pii = {1753-4631-4-S1-S10}, Pmid = {20522260}, Timestamp = {2010.08.24}, Url = {http://dx.doi.org/10.1186/1753-4631-4-S1-S10} } @Article{Maruyama2010, Title = {Modulus and direction of the neural current vector identify distinct functional connectivity modes between human MT+ areas.}, Author = {Masaki Maruyama and Andreas A Ioannides}, Journal = {J Neurosci Methods}, Year = {2010}, Month = {Jul}, Abstract = {Reconstruction of neural current sources from magnetoencephalography (MEG) data provides two independent estimates of the instantaneous current modulus and its direction.

Connectivity was quantified by mutual information values of paired time series of current moduli or directions, with the joint probability distribution estimated with an optimized Gaussian kernel. These time series were obtained from tomographic analysis of single-trial MEG responses to a visual motion stimulus. With a high-contrast stimulus, connectivity measures based on the modulus were relatively strong in the prestimulus period, continuing until 100ms after stimulus onset. The strongest modulus connectivity was produced with a long lag (19ms) of the right hMT+ after the left hMT+. On the other hand, connectivity measures based on direction were relatively strong after 100ms, with a short delay of less than 6ms. These results suggest that nonspecific and probably indirect communication between the homologous areas is turned, by the stimulus arrival, into more precise and direct communication through the corpus callosum. The orientation of the estimated current vector for the strong connectivity can be explained by the curvature of the active cortical sheet. The temporal patterns of modulus and directional connectivity were different at low contrast, but similar to those at high contrast.

Using functional magnetic resonance imaging, we found that unconscious neural priming in bilingual word recognition is language nonselective in the left midfusiform gyrus but exhibits a preference for the dominant language in the left posterior middle temporal gyrus (MTG). These early-stage components of reading were located slightly upstream of the left midlateral MTG, which exhibited enhanced response during a conscious switch of language. Effective connectivity analysis revealed that this language switch is triggered by reentrant signals from inferior frontal cortex and not by bottom-up signals from occipitotemporal cortex. We further confirmed that magnetic stimulation of the same inferior frontal region interferes with conscious language control but does not disrupt unconscious priming by masked words. Collectively, our results demonstrate that the neural bottleneck in the bilingual brain is a cross-language asymmetry of form-meaning association in inferolateral temporal cortex, which is overcome by a top-down cognitive control for implementing a task schema in each language.}, Doi = {10.1093/cercor/bhp290}, pdf = {D:\\\\Documents and Settings\\\\gs985873\\\\Desktop\\\\SITO WEB UNICOG\\\\html\\\\publications\\\\KN_Neuron_2006.pdf}, Institution = {Cognitive Neuroimaging Unit, NeuroSpin, CEA/SAC/DSV/I2BM, F-91191 Gif-sur-Yvette, France. kimihiro.nakamura@college-de-france.fr}, Language = {eng}, Medline-pst = {ppublish}, Owner = {gs985873}, Pii = {bhp290}, Pmid = {20051357}, Timestamp = {2011.02.16}, Url = {http://dx.doi.org/10.1093/cercor/bhp290} } @Article{Nakamura2010a, Title = {Symmetrical hemispheric priming in spatial neglect: A hyperactive left-hemisphere phenomenon?}, Author = {Kimihiro Nakamura and Tatsuhide Oga and Motohiko Takahashi and Tamaki Kuribayashi and Yuichi Kanamori and Takumi Matsumiya and Yutaka Maeno and Masahiro Yamamoto}, Journal = {Cortex}, Year = {2010}, Month = {Dec}, Abstract = {Hemispheric rivalry models of spatial neglect suggest that the left hemisphere becomes hyperactive following right-hemisphere lesions since the two hemispheres normally exert an inhibitory influence on each other via callosal connections.

Participants consisted of 12 neglect patients with right-hemisphere damage and three groups of control participants, i.e., 12 young healthy controls, 10 age-matched healthy controls and 10 right-hemisphere patients without spatial neglect. In each trial, participants made semantic categorization about a centrally presented target word which was preceded by a masked prime flashed either to the left or right visual field.

These results suggest that (1) the neglected hemifield can rapidly extract abstract information even from weak and normally non-perceptible visual stimuli, but that (2) the normal left hemispheric dominance in reading is absent in neglect patients probably because of the generalized hyperactivity of the left hemisphere.

To shed light on this issue, we performed a "colateralization analysis" over 209 healthy subjects: We investigated whether normal variations in the degree of left hemispheric asymmetry in areas involved in sentence listening and reading are mirrored in the asymmetry of areas involved in mental arithmetic. Within the language network, a region-of-interest analysis disclosed partially dissociated patterns of lateralization, inconsistent with an overall "dominance" model. Only two of these areas presented a lateralization during sentence listening and reading which correlated strongly with the lateralization of two regions active during calculation. Specifically, the profile of asymmetry in the posterior superior temporal sulcus during sentence processing covaried with the asymmetry of calculation-induced activation in the intraparietal sulcus, and a similar colateralization linked the middle frontal gyrus with the superior posterior parietal lobule.

Ever since, these claims have been debated and an astute synopsis and sceptical discussion was presented 40 years ago by MacDonald Critchley in this journal. Nonetheless, Gerstmann's syndrome has continued to intrigue both clinical neurologists and researchers in neuropsychology, and more frequently than not is described in textbooks as an example of parietal lobe damage.

Here, we test our proposed interpretation that this network underpins maintenance of tonic alertness. We used simultaneous acquisition of functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) in the absence of any paradigm to test an ensuing hypothesis, namely that spontaneous fluctuations in this ICN's activity (as measured by fMRI) should show a positive correlation with the electrical signatures of tonic alertness (as recorded by concurrent EEG). We found in human subjects (19 male, 7 female) that activity in a network comprising dorsal anterior cingulate cortex, anterior insula, anterior prefrontal cortex and thalamus is positively correlated with global field power (GFP) of upper alpha band (10-12 Hz) oscillations, the most consistent electrical index of tonic alertness. Conversely, and in line with earlier findings, alpha band power was negatively correlated with activity in another ICN, the so-called dorsal attention network which is most prominently involved in selective spatial attention.

To date, it has been used to extract sets of mutually correlated brain regions without prior information on the time course of these regions. Some of these sets of regions, interpreted as functional networks, have recently been used to provide markers of brain diseases and open the road to paradigm-free population comparisons. Such group studies raise the question of modeling subject variability within ICA: how can the patterns representative of a group be modeled and estimated via ICA for reliable inter-group comparisons? In this paper, we propose a hierarchical model for patterns in multi-subject fMRI datasets, akin to mixed-effect group models used in linear-model-based analysis. We introduce an estimation procedure, CanICA (Canonical ICA), based on i) probabilistic dimension reduction of the individual data, ii) canonical correlation analysis to identify a data subspace common to the group iii) ICA-based pattern extraction. In addition, we introduce a procedure based on cross-validation to quantify the stability of ICA patterns at the level of the group. We compare our method with state-of-the-art multi-subject fMRI ICA methods and show that the features extracted using our procedure are more reproducible at the group level on two datasets of 12 healthy controls: a resting-state and a functional localizer study.}, Doi = {10.1016/j.neuroimage.2010.02.010}, pdf = {http://www.unicog.org/publications/varoquaux_neuroimage.pdf}, Institution = {Parietal project team, INRIA, Saclay-Ile-de-France, Saclay, France. gael.varoquaux@normalesup.org}, Language = {eng}, Medline-pst = {ppublish}, Owner = {gs985873}, Pii = {S1053-8119(10)00161-8}, Pmid = {20153834}, Timestamp = {2010.06.22}, Url = {http://dx.doi.org/10.1016/j.neuroimage.2010.02.010} } @Article{ArnaudViarouge2010inpress, Title = {Number Line Compression and the Illusory Perception of Random Numbers}, Author = {Arnaud Viarouge, and Edward M.

This "time dilation effect" has been shown for a number of stimuli that differ from standard events along different feature dimensions (e.g. color, size, and dynamics). We performed an event-related functional magnetic resonance imaging (fMRI) study, while subjects viewed a stream of five visual events, all of which were static and of identical duration except the fourth one, which was a deviant target consisting of either a looming or a receding disc. The duration of the target was systematically varied and participants judged whether the target was shorter or longer than all other events. A time dilation effect was observed only for looming targets. Relative to the static standards, the looming as well as the receding targets induced increased activation of the anterior insula and anterior cingulate cortices (the "core control network"). The decisive contrast between looming and receding targets representing the time dilation effect showed strong asymmetric activation and, specifically, activation of cortical midline structures (the "default network"). These results provide the first evidence that the illusion of temporal dilation is due to activation of areas that are important for cognitive control and subjective awareness. The involvement of midline structures in the temporal dilation illusion is interpreted as evidence that time perception is related to self-referential processing.}, Doi = {10.3389/neuro.09.002.2010}, pdf = {http://www.unicog.org/publications/10.3389-neuro.09-002.2010.pdf}, Institution = {Department of Empirical and Analytical Psychophysics, Institute for Frontier Areas in Psychology and Mental Health Freiburg, Germany.}, Owner = {gs985873}, Pmid = {20161994}, Timestamp = {2010.03.08}, Url = {http://dx.doi.org/10.3389/neuro.09.002.2010} } @Article{Zylberberg2010, Title = {The brain's router: a cortical network model of serial processing in the primate brain}, Author = {Ariel Zylberberg and Diego Fernandez Slezak and Pieter R Roelfsema and Stanislas Dehaene and Mariano Sigman}, Journal = {PLoS Comput Biol}, Year = {2010}, Month = {Apr}, Number = {4}, Pages = {e1000765}, Volume = {6}, Abstract = {The human brain efficiently solves certain operations such as object recognition and categorization through a massively parallel network of dedicated processors. However, human cognition also relies on the ability to perform an arbitrarily large set of tasks by flexibly recombining different processors into a novel chain. This flexibility comes at the cost of a severe slowing down and a seriality of operations (100-500 ms per step). A limit on parallel processing is demonstrated in experimental setups such as the psychological refractory period (PRP) and the attentional blink (AB) in which the processing of an element either significantly delays (PRP) or impedes conscious access (AB) of a second, rapidly presented element. Here we present a spiking-neuron implementation of a cognitive architecture where a large number of local parallel processors assemble together to produce goal-driven behavior. The precise mapping of incoming sensory stimuli onto motor representations relies on a "router" network capable of flexibly interconnecting processors and rapidly changing its configuration from one task to another. Simulations show that, when presented with dual-task stimuli, the network exhibits parallel processing at peripheral sensory levels, a memory buffer capable of keeping the result of sensory processing on hold, and a slow serial performance at the router stage, resulting in a performance bottleneck. The network captures the detailed dynamics of human behavior during dual-task-performance, including both mean RTs and RT distributions, and establishes concrete predictions on neuronal dynamics during dual-task experiments in humans and non-human primates.}, Doi = {10.1371/journal.pcbi.1000765}, pdf = {http://www.unicog.org/publications/journal.pcbi.1000765.pdf}, Institution = {Laboratory of Integrative Neuroscience, Physics Department, University of Buenos Aires, Buenos Aires, Argentina. arielz@df.uba.ar}, Keywords = {Action Potentials; Analysis of Variance; Attentional Blink; Cerebral Cortex, physiology; Cognition; Humans; Models, Neurological; Nerve Net, physiology; Reaction Time; Stochastic Processes; Task Performance and Analysis}, Language = {eng}, Medline-pst = {epublish}, Owner = {gs985873}, Pmid = {20442869}, Timestamp = {2011.01.07}, Url = {http://dx.doi.org/10.1371/journal.pcbi.1000765} } @Book{StanislasDehaene2009, Title = {Parole et musique}, Author = {Dehaene, Stanislas and Petit, Christine}, Publisher = {Odile Jacob}, Year = {2009}, Owner = {gs985873}, Timestamp = {2009.09.02} } @Book{September2009, Title = {Reading in the brain}, Author = {Dehaene, Stanislas}, Publisher = {Penguin Viking}, Year = {2009}, Owner = {gs985873}, Timestamp = {2009.07.02}, Url = {http://pagesperso-orange.fr/readinginthebrain/index} } @InCollection{Buiatti2010inpress, Title = {Analisi multidimensionale della dinamica neurale di un processo cognitivo}, Author = {Marco Buiatti}, Booktitle = {Bioingegneria per le Scienze Cognitive}, Publisher = {Edizioni Patron, Bologna (Italy)}, Year = {2009}, pdf = {http://www.unicog.org/publications/BuiattiBioingegneria2009.pdf}, Owner = {gs985873}, Timestamp = {2010.05.07} } @InCollection{S2009october, Title = {Ventral and dorsal contribution to word reading}, Author = {Cohen, L. and Dehaene, S.}, Booktitle = {Cognitive Neuroscience, 4th edition}, Publisher = {MIT Press}, Year = {2009}, Editor = {M.S.

Some models stipulate that the active maintenance of perceptual representations across time requires consciousness.

Local violations led to an early response in auditory cortex, independent of attention or the presence of a concurrent visual task, whereas global violations led to a late and spatially distributed response that was only present when subjects were attentive and aware of the violations. We could detect the global effect in individual subjects using functional MRI and both scalp and intracerebral event-related potentials. Recordings from 8 noncommunicating patients with disorders of consciousness confirmed that only conscious individuals presented a global effect. Taken together these observations suggest that the presence of the global effect is a signature of conscious processing, although it can be absent in conscious subjects who are not aware of the global auditory regularities.

From around 2 months of age, infants are able to correctly match the vowel they hear with the appropriate articulating face. However, there is no behavioral evidence of integrated audiovisual perception until 4 months of age, at the earliest, when an illusory percept can be created by the fusion of the auditory stimulus and of the facial cues (McGurk effect). To understand how infants initially match the articulatory movements they see with the sounds they hear, we recorded high-density ERPs in response to auditory vowels that followed a congruent or incongruent silently articulating face in 10-week-old infants. In a first experiment, we determined that auditory-visual integration occurs during the early stages of perception as in adults. The mismatch response was similar in timing and in topography whether the preceding vowels were presented visually or aurally. In the second experiment, we studied audiovisual integration in the linguistic (vowel perception) and nonlinguistic (gender perception) domain. We observed a mismatch response for the both types of change at similar latencies. Their topographies were significantly different demonstrating that cross-modal integration of these features is computed in parallel by two different networks. Indeed, brain source modeling revealed that phoneme and gender computations were lateralized toward the left and toward the right hemisphere, respectively, suggesting that each hemisphere possesses an early processing bias. We also observed repetition suppression in temporal regions and repetition enhancement in frontal regions.

Here we used a frequency-tagging approach to explore the neural mechanisms underlying word learning while listening to continuous speech. High-density EEG was recorded in adults listening to a concatenation of either random syllables or tri-syllabic artificial words, with or without subliminal pauses added every three syllables. Peaks in the EEG power spectrum at the frequencies of one and three syllables occurrence were used to tag the perception of a monosyllabic or tri-syllabic structure, respectively. Word streams elicited the suppression of a one-syllable frequency peak, steadily present during random streams, suggesting that syllables are no more perceived as isolated segments but bounded to adjacent syllables. Crucially, three-syllable frequency peaks were only observed during word streams with pauses, and were positively correlated to the explicit recall of the detected words. This result shows that pauses facilitate a fast, explicit and successful extraction of words from continuous speech, and that the frequency-tagging approach is a powerful tool to track brain responses to different hierarchical units of the speech structure}, Doi = {10.1016/j.neuroimage.2008.09.015}, pdf = {http://www.unicog.org/publications/BuiattiPenaDehaene_YNIMG_5698.PDF}, Institution = {INSERM, U562, Cognitive Neuroimaging Unit, F-91191 Gif/Yvette, France. marco.buiatti@unitn.it}, Owner = {pallier}, Pii = {S1053-8119(08)00998-1}, Pmid = {18929668}, Timestamp = {2008.12.31}, Url = {http://dx.doi.org/10.1016/j.neuroimage.2008.09.015} } @Article{Cantlon2008, Title = {The Neural Development of an Abstract Concept of Number.}, Author = {Jessica F Cantlon and Melissa E Libertus and Philippe Pinel and Stanislas Dehaene and Elizabeth M Brannon and Kevin A Pelphrey}, Journal = {J Cogn Neurosci}, Year = {2009}, Month = {Nov}, Pages = {2217-29}, Volume = {21(11)}, Abstract = {Abstract As literate adults, we appreciate numerical values as abstract entities that can be represented by a numeral, a word, a number of lines on a scorecard, or a sequence of chimes from a clock.

Only studies in early life can help us to understand how such asymmetries arise during brain development, and to which point structural left-right differences are the source or the consequence of functional lateralization. In this study, we aimed to provide new in vivo structural markers of hemispheric asymmetries in infants from 1 to 4 months of age, with diffusion tensor imaging. We used 3 complementary analysis methods based on local diffusion indices and spatial localizations of tracts. After a prospective approach over the whole brain, we demonstrated early leftward asymmetries in the arcuate fasciculus and in the cortico-spinal tract.

Yet although the areas responding overall during numerical tasks have been well defined by neuroimaging, a direct demonstration of individual number coding by spatial patterns has thus far been elusive. RESULTS: We used multivariate pattern recognition on high-resolution functional imaging data to decode the information content of fine-scale signals evoked by different individual numbers. Parietal activation patterns for individual numerosities could be accurately discriminated and generalized across changes in low-level stimulus parameters. Distinct patterns were evoked by symbolic and nonsymbolic number formats, and individual digits were less accurately decoded (albeit still with significant accuracy) than numbers of dots. Interestingly, the numerosity of dot sets could be predicted above chance from the brain activation patterns evoked by digits, but not vice versa. Finally, number-evoked patterns changed in a gradual fashion as a function of numerical distance for the nonsymbolic notation, compatible with some degree of orderly layout of individual number representations. CONCLUSIONS: Our findings demonstrate partial format invariance of individual number codes that is compatible with more numerous but more broadly tuned populations for nonsymbolic than for symbolic numbers, as postulated by recent computational models. In more general terms, our results illustrate the potential of functional magnetic resonance imaging pattern recognition to understand the detailed format of representations within a single semantic category, and beyond sensory cortical areas for which columnar architectures are well established.}, Doi = {10.1016/j.cub.2009.08.047}, pdf = {http://www.unicog.org/publications/Eger_2009_deciphering_currbio.pdf}, Institution = {INSERM U562, F-91191 Gif/Yvette, France; NeuroSpin, Institut d'Imagerie Biomédicale, Direction des Sciences du Vivant, Commissariat à l'Energie Atomique, F-91191 Gif/Yvette, France; Université Paris-Sud, F-91405 Orsay, France.}, Owner = {gs985873}, Pii = {S0960-9822(09)01623-6}, Pmid = {19781939}, Timestamp = {2009.10.14}, Url = {http://dx.doi.org/10.1016/j.cub.2009.08.047} } @Article{Gaillard.2009, Title = {Converging Intracranial Markers of Conscious Access}, Author = {Raphael Gaillard and Stanislas Dehaene and Claude Adam and Stephane Clemenceau and Dominique Hasboun and Michel Baulac and Laurent Cohen and and Lionel Naccache}, Journal = {PLoS Biol}, Year = {2009}, Number = {3}, Volume = {7}, Abstract = {We compared conscious and nonconscious processing of briefly flashed words using a visual masking procedure while recording intracranial electroencephalogram (iEEG) in ten patients.

In passive conditions subjects simply watched the central letter stimuli and in active conditions they had to report occurrence of pre-defined targets in a rapid serial letter stream. Onset of the central letter stream enhanced activity in V1 representations of the stimulated region. Within representations of the periphery activation decreased and finally turned into deactivation with increasing distance from the stimulated location. This pattern was most pronounced in the active conditions and during the presence of peripheral stimuli.

METHODS: We used structural and functional neuroimaging at high spatial resolution in healthy subjects to seek a shared cortical substrate of the Grundstrung posited by Gerstmann, ie, a common functional denominator accounting for this clinical tetrad. We construed a functional activation paradigm that mirrors each of the four clinical deficits in Gerstmann syndrome and determined cortical activation patterns. We then applied fiber tracking to diffusion tensor images and used cortical activation foci in the four functional domains as seed regions. RESULTS: None of the subjects showed parietal overlap of cortical activation patterns from the four cognitive domains. In every subject, however, the parietal activation patterns across all four domains consistently connected to a small region of subcortical parietal white matter at a location that is congruent with the lesion in a well-documented case of pure Gerstmann syndrome.

Our evidence from intact functional neuroanatomy suggests that pure forms of Gerstmann's tetrad do not arise from lesion to a shared cortical substrate but from intraparietal disconnection after damage to a focal region of subcortical white matter.}, Crossref = {A disconnection account of Gerstmann syndrome: functional neuroanatomy evidence.}, Doi = {10.1002/ana.21776}, pdf = {http://www.unicog.org/publications/rusconi_aon.pdf}, Institution = {Institut Nationale de la Santé et de la Recherche Médicale (INSERM), Unité 562, Gif-sur-Yvette, France.}, Keywords = {Brain Mapping, methods; Cerebral Cortex, anatomy /&/ histology/physiology/physiopathology; Functional Laterality, physiology; Gerstmann Syndrome, pathology/physiopathology; Humans; Magnetic Resonance Imaging, methods; Male; Psychomotor Performance, physiology; Young Adult}, Language = {eng}, Medline-pst = {ppublish}, Owner = {gs985873}, Pmid = {19938150}, Timestamp = {2010.06.22}, Url = {http://dx.doi.org/10.1002/ana.21776} } @Article{Sackur2009, Title = {The cognitive architecture for chaining of two mental operations.}, Author = {Jérôme Sackur and Stanislas Dehaene}, Journal = {Cognition}, Year = {2009}, Month = {May}, Number = {2}, Pages = {187--211}, Volume = {111}, Abstract = {A simple view, which dates back to Turing, proposes that complex cognitive operations are composed of serially arranged elementary operations, each passing intermediate results to the next. However, whether and how such serial processing is achieved with a brain composed of massively parallel processors, remains an open question. Here, we study the cognitive architecture for chained operations with an elementary arithmetic algorithm: we required participants to add (or subtract) two to a digit, and then compare the result with five. In four experiments, we probed the internal implementation of this task with chronometric analysis, the cued-response method, the priming method, and a subliminal forced-choice procedure. We found evidence for an approximately sequential processing, with an important qualification: the second operation in the algorithm appears to start before completion of the first operation. Furthermore, initially the second operation takes as input the stimulus number rather than the output of the first operation. Thus, operations that should be processed serially are in fact executed partially in parallel. Furthermore, although each elementary operation can proceed subliminally, their chaining does not occur in the absence of conscious perception. Overall, the results suggest that chaining is slow, effortful, imperfect (resulting partly in parallel rather than serial execution) and dependent on conscious control.}, Doi = {10.1016/j.cognition.2009.01.010}, pdf = {http://www.unicog.org/publications/SackurDehaene_ChainingOfArithmeticOperations_Cognition2009.pdf}, Institution = {Laboratoire de Sciences Cognitives et Psycholinguistique, EHESS/CNRS/DEC-ENS, Département d'Etudes Cognitives, Ecole Normale Supérieure, Paris, France. jerome.sackur@gmail.com}, Owner = {gs985873}, Pii = {S0010-0277(09)00039-0}, Pmid = {19306995}, Timestamp = {2009.06.24}, Url = {http://dx.doi.org/10.1016/j.cognition.2009.01.010} } @Article{Sadaghiani2009, Title = {Distributed and antagonistic contributions of ongoing activity fluctuations to auditory stimulus detection.}, Author = {Sepideh Sadaghiani and Guido Hesselmann and Andreas Kleinschmidt}, Journal = {Journal of Neuroscience}, Year = {2009}, Month = {Oct}, Number = {42}, Pages = {13410--13417}, Volume = {29}, Abstract = {Recent studies have shown that ongoing activity fluctuations influence trial-by-trial perception of identical stimuli.

We tested whether these observations generalize to another as of yet unassessed sensory modality, audition, and a nonspatial but memory-dependent paradigm. In a sparse event-related functional magnetic resonance imaging design, we investigated detection of auditory near-threshold stimuli as a function of prestimulus baseline activity in early auditory cortex as well as several distributed networks that were defined on the basis of resting state functional connectivity. In accord with previous studies, hits were associated with higher prestimulus activity in related early sensory cortex as well as in a system comprising anterior insula, anterior cingulate, and thalamus, which other studies have related to processing salience and maintaining task set. In contrast to previous studies, however, higher prestimulus activity in the so-called dorsal attention system of frontal and parietal cortex biased toward misses, whereas higher activity in the so-called default mode network that includes posterior cingulate and precuneus biased toward hits. These results contradict a simple dichotomic view on the function of these two latter brain systems where higher ongoing activity in the dorsal attention network would facilitate perceptual performance, and higher activity in the default mode network would deteriorate perceptual performance.

We presented adult readers with words that were progressively degraded in three different ways (word rotation, letter spacing, and displacement to the visual periphery). Behaviorally, we identified degradation thresholds above which reading difficulty increased non-linearly, with the concomitant emergence of a word length effect on reading latencies reflecting serial reading strategies. fMRI activations were correlated with reading difficulty in bilateral occipito-temporal and parietal regions, reflecting the strategies required to identify degraded words. A core region of the intraparietal cortex was engaged in all modes of degradation. Furthermore, in the ventral pathway, word degradation led to an amplification of activation in the posterior visual word form area, at a level thought to encode single letters.

Since cortical folding occurs early during brain development, these structural abnormalities might be present long before the appearance of functional symptoms. So far, the precise mechanisms responsible for such alteration in the convolution pattern during intra-uterine or post-natal development are still poorly understood. Here we compared anatomical and functional brain development in vivo among 45 premature newborns who experienced different intra-uterine environments: 22 normal singletons, 12 twins and 11 newborns with intrauterine growth restriction (IUGR). Using magnetic resonance imaging (MRI) and dedicated post-processing tools, we investigated early disturbances in cortical formation at birth, over the developmental period critical for the emergence of convolutions (26-36 weeks of gestational age), and defined early 'endophenotypes' of sulcal development. We demonstrated that twins have a delayed but harmonious maturation, with reduced surface and sulcation index compared to singletons, whereas the gyrification of IUGR newborns is discordant to the normal developmental trajectory, with a more pronounced reduction of surface in relation to the sulcation index compared to normal newborns.

Here, we investigated the microstructural correlates of early functional development by combining DTI and visual event-related potentials (VEPs) in 15 one- to 4-month-old healthy infants. Interindividual variations of the apparent conduction speed, computed from the latency of the first positive VEP wave (P1), were significantly correlated with the infants' age and DTI indices measured in the optic radiations.

The format of object representation in the human brain has thus far mostly been studied using adaptation paradigms because the neuronal layout of object selectivities was thought to be beyond the resolution of conventional functional MRI (fMRI). Recently, however, multivariate pattern recognition succeeded in discriminating fMRI responses of object-selective cortex to different object exemplars within a given category. Here, we use increased spatial fMRI resolution to explore size sensitivity and tolerance to size change of response patterns evoked by object exemplars across a range of three sizes. Results from Support Vector Classification on responses of the human lateral occipital complex (LOC) show that discrimination of size (for a given object) and discrimination of objects across changes in size depended on the amount of size difference. Even across the largest amount of size change, accuracy for generalization was still significant in LOC, whereas the same comparison was at chance performance in early visual (calcarine) cortex. Analyzing subregions, we further found an anterior-posterior gradient in the degree of size sensitivity and size generalization within the posterior-dorsal and anterior-ventral parts of LOC. These results speak against fully size-invariant representation of object information in human LOC and are hence congruent with findings in monkeys showing object identity and size information in population activity of inferotemporal cortex.

To test whether this result generalizes from the visual object domain to other perceptual and neural systems, the current study investigated the effect of ongoing signal fluctuations in motion-sensitive brain regions on the perception of coherent visual motion. We determined motion coherence thresholds individually for each subject using a dynamic random dot display. During functional magnetic resonance imaging (fMRI), brief events of subliminal, supraliminal, and periliminal coherent motion were presented with long and variable interstimulus intervals between them. On each trial, subjects reported whether they had perceived "coherent" or "random" motion, and fMRI signal time courses were analyzed separately as a function of stimulus and percept type. In the right motion-sensitive occipito-temporal cortex (hMT+), coherent percepts of periliminal stimuli yielded a larger stimulus-evoked response than random percepts. Prestimulus baseline activity in this region was also significantly higher in these coherent trials than in random trials. As in our previous study, however, the relation between ongoing and evoked activity was not additive but interacted with perceptual outcome. Our data thus suggest that endogenous fluctuations in baseline activity have a generic effect on subsequent perceptual decisions.

Examples are derived from simultaneous electroencephalography (EEG) and electromyography (EMG) during functional MRI in cognitive and systems neuroscience as well as in clinical neurology, in particular in epilepsy and movement disorders. We conclude with an outlook on current and future efforts to achieve true integration of electrical and haemodynamic measures of neuronal activity using data fusion models.}, doi = {10.1016/j.neuroimage.2007.11.039}, pdf = {http://www.unicog.org/publications/Laufs_2008_NeuroImage.pdf}, institution = {Johann Wolfgang Goethe-Universität, Zentrum der Neurologie und Neurochirurgie, Klinik für Neurologie, Theodor-Stern-Kai 7, 60590 Frankfurt am Main, Germany. helmut@laufs.com}, keywords = {Algorithms; Artifacts; Brain; Data Interpretation, Statistical; Electroencephalography; Electromyography; Electrophysiology; Humans; Magnetic Resonance Imaging}, owner = {pallier}, pii = {S1053-8119(07)01073-7}, pmid = {18201910}, timestamp = {2009.01.30}, url = {http://dx.doi.org/10.1016/j.neuroimage.2007.11.039}, } @Article{Makni2008, Title = {A fully Bayesian approach to the parcel-based detection-estimation of brain activity in fMRI}, Author = {Salima Makni and Jérôme Idier and Thomas Vincent and Bertrand Thirion and Ghislaine Dehaene-Lambertz and Philippe Ciuciu}, Journal = {Neuroimage}, Year = {2008}, Month = {Jul}, Number = {3}, Pages = {941--969}, Volume = {41}, Abstract = {Within-subject analysis in fMRI essentially addresses two problems, i.e., the detection of activated brain regions in response to an experimental task and the estimation of the underlying dynamics, also known as the characterisation of Hemodynamic response function (HRF). So far, both issues have been treated sequentially while it is known that the HRF model has a dramatic impact on the localisation of activations and that the HRF shape may vary from one region to another. In this paper, we conciliate both issues in a region-based joint detection-estimation framework that we develop in the Bayesian formalism. Instead of considering function basis to account for spatial variability, spatially adaptive General Linear Models are built upon region-based non-parametric estimation of brain dynamics. Regions are first identified as functionally homogeneous parcels in the mask of the grey matter using a specific procedure [Thirion, B., Flandin, G., Philippe Pinel, Roche, A., Ciuciu, P., Poline, J.-B., August 2006. Dealing with the shortcomings of spatial normalization: Multi-subject parcellation of fMRI datasets. Hum. Brain Mapp. 27 (8), 678-693.]. Then, in each parcel, prior information is embedded to constrain this estimation. Detection is achieved by modelling activating, deactivating and non-activating voxels through mixture models within each parcel. From the posterior distribution, we infer upon the model parameters using Markov Chain Monte Carlo (MCMC) techniques. Bayesian model comparison allows us to emphasize on artificial datasets first that inhomogeneous gamma-Gaussian mixture models outperform Gaussian mixtures in terms of sensitivity/specificity trade-off and second that it is worthwhile modelling serial correlation through an AR(1) noise process at low signal-to-noise (SNR) ratio. Our approach is then validated on an fMRI experiment that studies habituation to auditory sentence repetition.

Because the perceptual objects that are recognized by the speech perception enter into subsequent linguistic computation, the format that is used for lexical representation and processing fundamentally constrains the speech perceptual processes. Consequently, theories of speech perception must, at some level, be tightly linked to theories of lexical representation. Minimally, speech perception must yield representations that smoothly and rapidly interface with stored lexical items. Adopting the perspective of Marr, we argue and provide neurobiological and psychophysical evidence for the following research programme. First, at the implementational level, speech perception is a multi-time resolution process, with perceptual analyses occurring concurrently on at least two time scales (approx. 20-80 ms, approx. 150-300 ms), commensurate with (sub)segmental and syllabic analyses, respectively. Second, at the algorithmic level, we suggest that perception proceeds on the basis of internal forward models, or uses an 'analysis-by-synthesis' approach. Third, at the computational level (in the sense of Marr), the theory of lexical representation that we adopt is principally informed by phonological research and assumes that words are represented in the mental lexicon in terms of sequences of discrete segments composed of distinctive features. One important goal of the research programme is to develop linking hypotheses between putative neurobiological primitives (e.g. temporal primitives) and those primitives derived from linguistic inquiry, to arrive ultimately at a biologically sensible and theoretically satisfying model of representation and computation in speech.}, Doi = {10.1098/rstb.2007.2160}, Institution = {Department of Linguistics, University of Maryland, College Park, MD 20742, USA. dpoeppel@umd.edu}, Keywords = {Algorithms; Brain Mapping; Computer Simulation; Humans; Linguistics; Models, Theoretical; Neurobiology; Speech Perception, physiology}, Language = {eng}, Medline-pst = {ppublish}, Owner = {gs985873}, Pii = {TM425571U1117682}, Pmid = {17890189}, Timestamp = {2013.09.09}, Url = {http://dx.doi.org/10.1098/rstb.2007.2160} } @Article{Poupon2008, Title = {Real-time MR diffusion tensor and Q-ball imaging using Kalman filtering.}, Author = {Cyril Poupon and Alexis Roche and Jessica Dubois and Jean-François Mangin and Fabrice Poupon}, Journal = {Med Image Anal}, Year = {2008}, Month = {Oct}, Number = {5}, Pages = {527--534}, Volume = {12}, Abstract = {Diffusion magnetic resonance imaging (dMRI) has become an established research tool for the investigation of tissue structure and orientation.

Because the Kalman filter is designed to be an incremental algorithm, it naturally enables updating the model estimate after the acquisition of any new diffusion-weighted volume. Processing diffusion models and maps during ongoing scans provides a new useful tool for clinicians, especially when it is not possible to predict how long a subject may remain still in the magnet. First, we introduce the general linear models corresponding to the two diffusion tensor and analytical Q-ball models of interest.

Temporal stability and functional sensitivity were increased through optimization of all imaging parameters and Tikhonov regularization of parallel reconstruction. Two human volunteers were scanned with parallel EVI in a 1.5T whole-body MR system, while submitted to a slow event-related auditory paradigm. RESULTS: Thanks to parallel acquisition, the EVI volumes display a low level of geometric distortions and signal losses. After removal of low-frequency drifts and physiological artifacts, activations were detected in the temporal lobes of both volunteers and voxelwise hemodynamic response functions (HRF) could be computed. On these HRF different habituation behaviors in response to sentence repetition could be identified.

Alternatively, subitizing might rely on a distinct process dedicated to small numerosities.

One experience of time is the perception of duration, which is not isomorphic to physical duration and can be distorted by a number of factors. Yet, the critical features generating these perceptual shifts in subjective duration are not understood.We used prospective duration judgments within and across sensory modalities to examine the effect of stimulus predictability and feature change on the perception of duration. First, we found robust distortions of perceived duration in auditory, visual and auditory-visual presentations despite the predictability of the feature changes in the stimuli. For example, a looming disc embedded in a series of steady discs led to time dilation, whereas a steady disc embedded in a series of looming discs led to time compression. Second, we addressed whether visual (auditory) inputs could alter the perception of duration of auditory (visual) inputs. When participants were presented with incongruent audio-visual stimuli, the perceived duration of auditory events could be shortened or lengthened by the presence of conflicting visual information; however, the perceived duration of visual events was seldom distorted by the presence of auditory information and was never perceived shorter than their actual durations.These results support the existence of multisensory interactions in the perception of duration and, importantly, suggest that vision can modify auditory temporal perception in a pure timing task. Insofar as distortions in subjective duration can neither be accounted for by the unpredictability of an auditory, visual or auditory-visual event, we propose that it is the intrinsic features of the stimulus that critically affect subjective time distortions.}, Doi = {10.1371/journal.pone.0001437}, Institution = {Division of Biology, California Institute of Technology, Pasadena, California, United States of America. vvw@caltech.edu}, Keywords = {Adult; Female; Humans; Male; Perception; Photic Stimulation; Time}, Language = {eng}, Medline-pst = {epublish}, Owner = {gs985873}, Pmid = {18197248}, Timestamp = {2013.09.09}, Url = {http://dx.doi.org/10.1371/journal.pone.0001437} } @Article{Kriegstein.2008, Title = {Simulation of talking faces in the human brain improves auditory speech recognition.}, Author = {von Kriegstein, Katharina and Ozgür Dogan and Martina Grüter and Anne-Lise Giraud and Christian A Kell and Thomas Grüter and Andreas Kleinschmidt and Stefan J Kiebel}, Journal = {Proc Natl Acad Sci U S A}, Year = {2008}, Month = {May}, Number = {18}, Pages = {6747--6752}, Volume = {105}, Abstract = {Human face-to-face communication is essentially audiovisual.

To test this hypothesis, we performed behavioral and neuroimaging experiments in two groups: subjects with a face recognition deficit (prosopagnosia) and matched controls. The results show that observing a specific person talking for 2 min improves subsequent auditory-only speech and speaker recognition for this person. In both prosopagnosics and controls, behavioral improvement in auditory-only speech recognition was based on an area typically involved in face-movement processing. Improvement in speaker recognition was only present in controls and was based on an area involved in face-identity processing.

By reviewing what is known about the localization of numerical cognition functions in the adult brain, the causes of acquired dyscalculia, and the normal development of numerical cognition, we propose several hypotheses for causes of developmental dyscalculia, including that of a core deficit of "number sense" related to an impairment in the horizontal intra- parietal sulcus (HIPS) area. We then discuss research on dyscalculia, including the contribution of recent imaging results in special populations, and evaluate to what extent this research supports our hypotheses.

In this article, we present a critical review of research on subliminal perception during masking and other related experimental conditions. Although initially controversial, the possibility that a broad variety of processes can be activated by a non-reportable stimulus is now well established. Behavioural findings of subliminal priming indicate that a masked word or digit can have an influence on perceptual, lexical and semantic levels, while neuroimaging directly visualizes the brain activation that it evokes in several cortical areas. This activation is often attenuated under subliminal presentation conditions compared to consciously reportable conditions, but there are sufficiently many exceptions, in paradigms such as the attentional blink, to indicate that high activation, per se, is not a sufficient condition for conscious access to occur. We conclude by arguing that for a stimulus to reach consciousness, two factors are jointly needed: (i) the input stimulus must have enough strength (which can be prevented by masking) and (ii) it must receive top-down attention (which can be prevented by drawing attention to another stimulus or task). This view leads to a distinction between two types of non-conscious processes, which we call subliminal and preconscious.

The results often reveal an amplification of posterior occipito-temporal activation and its extension into a parieto-frontal network. However, some of these effects might be due to a greater deployment of attentional or strategical processes in the conscious condition. Here, we examined the brain activity evoked by visible and invisible stimuli, both of which were irrelevant to the task. We collected fMRI data in a masking paradigm in which subliminal versus supraliminal letter strings were presented as primes while subjects focused attention on another subsequent, highly visible target word. Under those conditions, prime visibility was associated with greater activity confined to bilateral posterior occipito-temporal cortices, without extension into frontal and parietal cortices. However, supraliminal primes, compared with subliminal primes, evoked more extensive repetition suppression in a widely distributed set of parieto-frontal areas. Furthermore, only supraliminal primes caused phonological repetition enhancement in left inferior frontal and anterior insular cortex. Those results suggest a 2-stage view of conscious access: Relative to masked stimuli, unmasked stimuli elicit increased occipito-temporal activity, thus allowing them to compete for global conscious access and to induce priming in multiple distant areas.

Understanding the origins of this variability will require the elaboration of large multimodal databases compiling behavioral, anatomical, genetic and functional neuroimaging data over hundreds of subjects. With this goal in mind, we designed a simple and fast acquisition procedure based on a 5-minute functional magnetic resonance imaging (fMRI) sequence that can be run as easily and as systematically as an anatomical scan, and is therefore used in every subject undergoing fMRI in our laboratory. This protocol captures the cerebral bases of auditory and visual perception, motor actions, reading, language comprehension and mental calculation at an individual level. RESULTS: 81 subjects were successfully scanned. Before describing inter-individual variability, we demonstrated in the present study the reliability of individual functional data obtained with this short protocol. Considering the anatomical variability, we then needed to correctly describe individual functional networks in a voxel-free space. We applied then non-voxel based methods that automatically extract main features of individual patterns of activation: group analyses performed on these individual data not only converge to those reported with a more conventional voxel-based random effect analysis, but also keep information concerning variance in location and degrees of activation across subjects. CONCLUSION: This collection of individual fMRI data will help to describe the cerebral inter-subject variability of the correlates of some language, calculation and sensorimotor tasks. In association with demographic, anatomical, behavioral and genetic data, this protocol will serve as the cornerstone to establish a hybrid database of hundreds of subjects suitable to study the range and causes of variation in the cerebral bases of numerous mental processes.}, Doi = {10.1186/1471-2202-8-91}, pdf = {http://www.unicog.org/publications/PinelThirionPolineDehaene_LargeScaleDatabaseLocalizer_BMCneuroscience2007.pdf.pdf}, Institution = {INSERM U562/ IFR 49, Cognitive Neuroimaging Unit, Gif-sur-Yvette, France. philippe.pinel@cea.fr}, Keywords = {Acoustic Stimulation, methods; Adult; Brain Mapping, methods; Cognition, physiology; Databases, Factual; Female; Humans; Magnetic Resonance Imaging, methods; Male; Nerve Net, physiology; Photic Stimulation, methods; Time Factors}, Owner = {gs985873}, Pii = {1471-2202-8-91}, Pmid = {17973998}, Timestamp = {2009.06.24}, Url = {http://dx.doi.org/10.1186/1471-2202-8-91} } @Article{Poupon2007, Title = {Real-time MR diffusion tensor and Q-ball imaging using Kalman filtering.}, Author = {C.

We therefore hypothesized that patients with early MS would have an elevated masking threshold, because of an impairment of conscious perception whereas subliminal processing of masked stimuli would be preserved. Twenty-two patients with early MS and 22 normal controls performed two backward-masking experiments. We used Arabic digits as stimuli and varied quasi-continuously the temporal interval with a subsequent mask, thus allowing us to progressively "unmask" the stimuli. We finely quantified the visibility of the masked stimuli using both objective and subjective measures, thus obtaining accurate estimates of the threshold duration for access to consciousness. We also studied the priming effect caused by the variably masked numbers on a comparison task performed on a subsequently presented and highly visible target number. The threshold for access to consciousness of masked stimuli was elevated in MS patients compared to controls, whereas non-conscious processing of these stimuli, as measured by priming, was preserved.

To identify timing information from the slow blood oxygen level-dependent (BOLD) signal response, we use a simple analytic method, based on periodic stimulation and an analysis of covariation of the spectral parameters (phase and power spectrum at the stimulation frequency) with the different experimental conditions. We implement this strategy in a sequential task, where the onset and duration of different stages are under experimental control. We are able to detect changes in onset latency and in the duration of the response, in an invariant fashion across different brain regions, and reconstruct the stream of activations consistent with five distinct stages of processing of the task.

Despite recent advances in understanding the neural processes underlying such perceptual rivalry, a key question has remained unresolved: Does perceptual rivalry result merely from local bistability of neural activity patterns in sensory stimulus representations, or do higher-order areas play a causal role by shifting inference and, thus, initiating perceptual changes? We used functional MRI to measure brain activity while human observers reported successive spontaneous changes in perceived direction for an ambiguous apparent motion stimulus. In a control condition, the individual sequences of spontaneous perceptual switches during bistability were replayed by using a disambiguated version of the stimulus. Greater activations during spontaneous compared with stimulus-driven switches were observed in inferior frontal cortex bilaterally. Subsequent chronometric analyses of event-related signal time courses showed that, relative to activations in motion-sensitive extrastriate visual cortex, right inferior frontal cortex activation occurred earlier during spontaneous than during stimulus-driven perceptual changes. The temporal precedence of right inferior frontal activations suggests that this region participates in initiating spontaneous switches in perception during constant physical stimulation.

Nos recherches s'articulent autour des trois axes suivants : 1. Tout d'abord nous avons cherché à donner une caractérisation fine des représentations non-verbales de la numérosité, à l'aide d'un modèle mathématique, qui postule que les numérosités sont représentées sur un continuum interne, la ligne numérique interne. Les prédictions! du modèle s'accordent avec un ensemble de mesures expérimentales, sur des tâches de comparaison, d'addition et de soustraction de numérosités. Enfin, en confrontant les prédictions du modèle aux résultats d'une tâche d'estimation de numérosité que nous avons développée, nous avons pu conclure que la ligne numérique interne est compressive. 2. Par ailleurs, nos travaux sur l'estimation abordent la question des liens entre les représentations de numérosités et les numéraux de la langue. De manière spontanée, les sujets ont une tendance marquée à sous-estimer la numérosité des stimuli, mais la donnée d'un indice suffit à modifier radicalement la manière dont ils sont calibrés. De plus, le processus de calibration agit de manière globale sur toute la ligne numérique. 3. Enfin, que se passe-t-il en l'absence de représentations verbales pour les nombres ? A l'aide de la technique des potentiels évoqués (ERPs), nous avons montré que les bébés âgés de trois mois sont déjà sensibles à la numérosité. Par ailleurs, nos expériences chez les Indiens Mundurucus montrent qu'en l'absence d'un lexique pour les grands nombres, ceux-ci déploient les mêmes compétences que des occidentaux dans des tâches d'arithmétique sur la numérosité, tant qu'on n'exige qu'une réponse approximative. De plus, les Mundurucus possèdent un concept d'égalité exacte, transcendant leurs représentations non-verbales approximatives de numérosité, mais se trouvent limités dans la plupart des tâches d'arithmétique exacte, de fait qu'il leur manque un outil cognitif (analogue à notre procédure de comptage) pour évaluer! la numérosité exacte d'un ensemble.

We extended this general framework to the verbal domain, in order to investigate the role of the SMA in speech production. We conducted two speech production experiments with fMRI where we manipulated parameters such as familiarity, complexity or constraints on word selection. The results reveal a parcellation of the SMA into three distinct regions, according to their involvement in different aspects of word production.

Hence, we aimed at investigating individual brain areas involved in semantic and phonological auditory processes. We hypothesized that active rTMS targeted over Wernicke's area might modify the performance during a language-fragment-detection task. Sentences in native or foreign languages were presented to 12 right-handed male healthy volunteers during functional magnetic resonance imaging (fMRI). 3D-functional maps localized the posterior temporal activation (Wernicke) in each subject and MRI anatomical cortical landmarks were used to define Broca's pars opercularis (F3Op). A frameless stereotaxy system was used to guide the TMS coil position over Wernicke's and F3Op areas in each subject. Active and placebo randomized rTMS sessions were applied at 1 Hz, 110\% of motor threshold, during the same language-fragment-detection task. Accuracy and response time (RT) were recorded. RT was significantly decreased by active rTMS compared to placebo over Wernicke's area, and was more decreased for native than for foreign languages. No significant RT change was observed for F3Op area. rTMS conditions did not impair participants' accuracy. Thus, low-frequency rTMS over Wernicke's area can speed-up the response to a task tapping on native language perception in healthy volunteers.

In Experiment 2, small blocks of six sentences were presented in which either the speaker voice or the linguistic content of the sentence, or both, were repeated. Data analyses revealed a clear asymmetry: While two clusters in the left superior temporal sulcus showed identical repetition suppression whether the sentences were produced by the same speaker or different speakers, the homologous right regions were sensitive to sentence repetition only when the speaker voice remained constant. Thus, hemispheric left regions encode linguistic content while homologous right regions encode more details about extralinguistic features like speaker voice.

This finding has frequently been interpreted as indicating a low-level visual deficit. However, more recent models suggest that masking may also involve late and higher-level integrative processes, while leaving intact early bottom-up visual processing. OBJECTIVE: To test the hypothesis that the backward-masking deficit in schizophrenia corresponds to a deficit in the late stages of conscious perception, whereas the subliminal processing of masked stimuli is fully preserved. DESIGN: Twenty-eight patients with schizophrenia and 28 normal control subjects performed 2 backward-masking experiments. We used Arabic digits as stimuli and varied quasi-continuously the interval with a subsequent mask, thus allowing us to progressively unmask the stimuli. We finely quantified their degree of visibility using objective and subjective measures to evaluate the threshold duration for access to consciousness. We also studied the priming effect caused by the variably masked numbers in a comparison task performed on a subsequently presented and highly visible target number. RESULTS: The threshold delay between the digit and mask necessary for the conscious perception of the masked stimulus was longer in patients compared with controls. This higher consciousness threshold in patients was confirmed by an objective and a subjective measure, and both measures were highly correlated for the patients and controls. However, subliminal priming of masked numbers was effective and identical in patients and controls. CONCLUSIONS: Access to conscious report of masked stimuli is impaired in schizophrenia, whereas fast bottom-up processing of the same stimuli, as assessed by subliminal priming, is preserved.

The horizontal coordinate (along the backward-forward axis) is encoded by two encoding schemes, both relying on the firing times of one type of TG neuron, the 'contact cell'. The radial coordinate (from face outward) is encoded primarily by the firing magnitude of another type of TG neurons, the 'pressure cell'.

The sets and subsets were compared to conventional sets through their energy, condition number and rotational invariance. Schemes of 18 orientations were tested on a volunteer.

Diffusion maps obtained in vivo were close to those for uniform sets whatever the acquisition time was. This was not the case with conventional schemes, whose subset uniformity was insufficient.

The logic of this method consists of presenting words close to the threshold for conscious perception and examining whether their semantic content modulates performance in objective and subjective tasks. Our results disclose two independent sources of modulation of the threshold for access to consciousness. First, prior conscious perception of words increases the detection rate of the same words when they are subsequently presented with stronger masking.

Pictures of eyes were interleaved amongst images belonging to three human contexts (frontal-view faces, profiles or bodies) or non-human contexts (houses, cars or pliers). In adults, both profile and frontal-face contexts elicited suppression of the N170 response to eye pictures, indicating an access to a view-invariant representation of faces. In infants, a response suppression of the N290 component was recorded only in the context of frontal faces, while profile context induces a different effect (i.e., a P400 enhancement) on eye processing. This dissociation suggests that the view-invariant representation of faces is learned, as it is for other 3-D objects and needs more than 4 months of exposure to be established. In a follow-up study, where infants were exposed to a short movie showing people rotating their heads, the profile-induced P400 effect was speeded up, indicating that exposure to successive views of the same object is probably a way to build up adult-like face representations}, Doi = {10.1016/j.cognition.2006.01.004}, pdf = {http://www.unicog.org/publications/GligaDehaene_PrimingFaces_Cognition2006.pdf}, Keywords = {16488406}, Owner = {gdehaene}, Pii = {S0010-0277(06)00018-7}, Pmid = {16488406}, Timestamp = {2006.06.27}, Url = {http://dx.doi.org/10.1016/j.cognition.2006.01.004} } @Article{Golestani2006, Title = {{S}yntax production in bilinguals}, Author = {Narly Golestani and F-Xavier Alario and Sébastien Meriaux and Le Bihan, Denis and Stanislas Dehaene and Christophe Pallier}, Journal = {Neuropsychologia}, Year = {2006}, Number = {7}, Pages = {1029--1040}, Volume = {44}, Abstract = {We used fMRI to examine the functional correlates of syntactical processing in the first (L1) and second (L2) languages of non-proficient, late bilinguals.

RECENT FINDINGS: Functional neuroimaging studies in healthy human subjects have identified only two regions of ventral occipitotemporal cortex that invariantly respond to individual faces and visual words, respectively. The signature of face identity coding in the fusiform neural response was shown to be missing in a patient with prosopagnosia. Another case study established that a surgical lesion close to the region sensitive to visual words can result in pure alexia. SUMMARY: Evidence is increasing that functional specialization for processing face identity and visual word forms is restricted to two specialized sensory modules in the occipitotemporal cortex. A structural or functional lesion to face-sensitive and word-sensitive regions in the ventral occipitotemporal cortex can provide the most parsimonious account for the clinical syndromes of prosopagnosia and agnosic alexia. This review suggests that functional specialization should be considered in terms of whether exclusively one brain region (instead of many) underpins a defined function and not as whether this brain region underpins exclusively one cognitive function. Such functional specialization seems to exist for at least two higher-order visual perceptual functions, face and word identification}, Doi = {10.1097/01.wco.0000236619.89710.ee}, pdf = {http://www.unicog.org/publications/kleinschmidt_cohen_curropinneurol2006.pdf}, Keywords = {Dyslexia; Humans; Magnetic Resonance Imaging; Prosopagnosia; Reading; Recognition (Psychology)}, Owner = {chrplr}, Pii = {00019052-200608000-00010}, Pmid = {16914978}, Timestamp = {2007.01.23}, Url = {http://dx.doi.org/10.1097/01.wco.0000236619.89710.ee} } @Article{Kleinschmidt2006a, Title = {Cognitive control signals in visual cortex: flashes meet spotlights}, Author = {Andreas Kleinschmidt}, Journal = {Neuron}, Year = {2006}, Month = {Jul}, Number = {1}, Pages = {9--11}, Volume = {51}, Abstract = {At the intersection of two intensely belabored fields, primary visual cortex (V1) function and neural mechanisms of cognitive control, Jack et al.

Here, we explore several possible explanations for this discrepancy by re-analyzing in detail our previously reported data. Using single subject analyses as a starting point, we found that alpha power decreases are associated with fMRI signal increases that mostly follow two distinct patterns: either 'visual' areas in the occipital lobe or 'attentional' areas in the frontal and parietal lobe. On examination of the EEG spectra corresponding to these two fMRI patterns, we found greater relative theta power in sessions yielding the 'visual' fMRI pattern during alpha desynchronization and greater relative beta power in sessions yielding the 'attentional' fMRI pattern. The few sessions that fell into neither pattern featured the overall lowest theta and highest beta power. We conclude that the pattern of brain activation observed during spontaneous power reduction in the alpha band depends on the general level of brain activity as indexed over a broader spectral range in the EEG.

Using extracellular recordings from urethane-anesthetized rats and electrically induced whisking, we found that TG neurons encode radial distance primarily by the number of spikes fired. When an object was positioned closer to the whisker root, all touch-selective neurons recorded fired more spikes. Some of these cells responded exclusively to objects located near the base of whiskers, signaling proximal touch by an identity (labeled-line) code. A number of tonic touch-selective neurons also decreased delays from touch to the first spike and decreased interspike intervals for closer object positions. Information theory analysis revealed that near-certainty discrimination between two objects separated by 30\% of the length of whiskers was possible for some single cells. However, encoding reliability was usually lower as a result of large trial-by-trial response variability.

In particular, reading was disrupted (a) by rotating word by more than 50 degrees , providing an approximation of the invariance range for words encoding in the ventral pathway; (b) by separating letters with double spaces, revealing the limits of letter grouping into perceptual wholes; (c) by mirror-reversing words, showing that words escape the default mirror-invariant representation of visual objects in the ventral pathway.

Thus, charting the display conditions associated with preserved or impaired performance allowed us to infer properties of word coding in the normal ventral pathway and to delineate the roles of the parietal lobes in single-word recognition}, Doi = {10.1162/jocn.2006.18.12.1998}, pdf = {http://www.unicog.org/publications/vinckier_cohen_what-and-where-in-reading_JOCN2006.pdf}, Owner = {chrplr}, Pmid = {17129187}, Timestamp = {2007.01.23}, Url = {http://dx.doi.org/10.1162/jocn.2006.18.12.1998} } @Article{Wilson2006a, Title = {Principles underlying the design of "The Number Race", an adaptive computer game for remediation of dyscalculia}, Author = {Anna Juliet Wilson and Stanislas Dehaene and Philippe Pinel and Susannah Revkin and Laurent Cohen and David Cohen}, Journal = {Behav Brain Funct}, Year = {2006}, Number = {1}, Pages = {19}, Volume = {2}, Abstract = {ABSTRACT: BACKGROUND: Adaptive game software has been successful in remediation of dyslexia. Here we describe the cognitive and algorithmic principles underlying the development of similar software for dyscalculia. Our software is based on current understanding of the cerebral representation of number and the hypotheses that dyscalculia is due to a "core deficit" in number sense or in the link between number sense and symbolic number representations. METHODS: "The Number Race" software trains children on an entertaining numerical comparison task, by presenting problems adapted to the performance level of the individual child. We report full mathematical specifications of the algorithm used, which relies on an internal model of the child's knowledge in a multidimensional "learning space" consisting of three difficulty dimensions: numerical distance, response deadline, and conceptual complexity (from non-symbolic numerosity processing to increasingly complex symbolic operations). RESULTS: The performance of the software was evaluated both by mathematical simulations and by five weeks of use by nine children with mathematical learning difficulties. The results indicate that the software adapts well to varying levels of initial knowledge and learning speeds. Feedback from children, parents and teachers was positive. A companion article 1 describes the evolution of number sense and arithmetic scores before and after training. CONCLUSION: The software, open-source and freely available online, is designed for learning disabled children aged 5-8, and may also be useful for general instruction of normal preschool children.

Here we review the evidence for this hypothesis, and present results from an initial open-trial test of the software in a sample of nine 7-9 year old children with mathematical difficulties. METHODS: Children completed adaptive training on numerical comparison for half an hour a day, four days a week over a period of five-weeks. They were tested before and after intervention on their performance in core numerical tasks: counting, transcoding, base-10 comprehension, enumeration, addition, subtraction, and symbolic and non-symbolic numerical comparison. RESULTS: Children showed specific increases in performance on core number sense tasks. Speed of subitizing and numerical comparison increased by several hundred msec. Subtraction accuracy increased by an average of 23\%. Performance on addition and base-10 comprehension tasks did not improve over the period of the study. CONCLUSION: Initial open-trial testing showed promising results, and suggested that the software was successful in increasing number sense over the short period of the study.

Est-ce possible qu'une seconde langue (L2) "remplace" une première langue (L1), dans des circonstances particulières ? L'hypothèse de la période critique pour l'acquisition du langage prédit que les aires langagières du cerveau perdent la plasticité avec l'âge. Une conséquence de cette hypothèse est donc que l'exposition à une langue donnée pendant les premières années de vie laissera des traces permanentes dans le cerveau. Ceci implique que la perte complète d'une langue maternelle ne pourrait avoir lieu. L'autre conséquence de la perte de plasticité est la difficulté croissante en fonction de l'âge de l'apprenant. Des études de l'acquisition d'une deuxième langue et des cas de personnes privées de langage pendant les premières années de vie (les "enfants-loups" et parfois les sourds nés dans des familles d' entendants) portent des preuves en faveur de la perte de plasticité. Dans cette thèse nous explorons les traces éventuelles de la L1 apprise et `perdue'pendant l'enfance, et la compétence dans la L2 apprise plus tard dans l'enfance. Nous avons choisi d'étudier des adoptés d'origine étrangère pour examiner ces questions. Notre étude concerne des adultes d'origine coréenne adoptés par des familles francophones entre l'âge de 3 et 10 ans et ayant été complètement isolés de leur langue et culture d'origine depuis leur arrivé en France il y a 15 à 30 ans. Cette thèse comporte trois parties : 1.) la recherche de traces de mémoire linguistique et autres (reconnaissance de séries numériques, de mots, de séries de jours de la semaine, de morphologie faciale) ; 2.) la recherche de traces éventuelles de la phonologie du coréen (discrimination de phonèmes, entra?nement aux sons du coréen) et 3.) l'évaluation de certains aspects du français (genre grammatical , phonotactique). Nous avons comparé les résultats des adoptés à ceux de francophones sans connaissances du coréen dans chaque expérience, et à ceux de Coréens natifs résidant en France pour certaines expériences. Les expériences de mémoire ont révélé l'existence de très peu de traces du coréen et d'autres types de souvenirs. De la même façon, les expériences de phonologie du coréen ont montré un comportement similaire à celui des francophones, et ceci indépendamment de la réexposition de certains adoptés à la langue coréenne lors de séjours de courte durée en Corée. Ces résultats nous suggèrent soit une perte du coréen, soit une inaccessibilité importante à cette langue par les adoptés. Les performances des adoptés sur les tests de français sont également semblables à celles des francophones et diffèrent de celle des Coréens natifs, indiquant une bonne ma?trise des aspects du français difficiles pour des Coréens. L'ensemble des données montre que les adoptés coréens sont devenus comme des francophones natifs dans leur traitement langagier. L'important rôle joué par la plasticité du système langagier chez les adoptés est corroboré par nos résultats, qui suggèrent qu'une langue maternelle peut être facilement remplacée par une autre langue pendant l'enfance. Il y a une convergence entre nos résultats et ceux d'études de cas d'attrition langagière chez des jeunes enfants adoptés montrant que la L1 est rapidement oubliée (Nicoladis \& Grabois, 2002 ; Isurin, 2000), alors que la L2 est vite assimilée}, pdf = {http://www.pallier.org/papers/Ventureyra.thesefinal.pdf}, Owner = {chrplr}, Timestamp = {2007.01.24} } @InCollection{Dehaene2005e, Title = {Imaging conscious and subliminal word processing}, Author = {Stanislas Dehaene}, Booktitle = {Developing individuality in the human brain : A tribute to Michael Posner}, Publisher = {American Psychological Association}, Year = {2005}, Editor = {U Mayr, E.

We use computer simulations to explore the conditions under which spontaneous activity emerges from a simplified model of multiple interconnected thalamocortical columns linked by long-range, top-down excitatory axons, and to examine its interactions with stimulus-induced activation. Simulations help characterize two main states of activity. First, spontaneous gamma-band oscillations emerge at a precise threshold controlled by ascending neuromodulator systems. Second, within a spontaneously active network, we observe the sudden "ignition" of one out of many possible coherent states of high-level activity amidst cortical neurons with long-distance projections. During such an ignited state, spontaneous activity can block external sensory processing. We relate those properties to experimental observations on the neural bases of endogenous states of consciousness, and particularly the blocking of access to consciousness that occurs in the psychophysical phenomenon of "inattentional blindness," in which normal subjects intensely engaged in mental activity fail to notice salient but irrelevant sensory stimuli.

This perceptual switch modifies their discrimination abilities, enhancing perception of differences that cross phonemic boundaries while diminishing perception of differences within phonemic categories. Using high-density evoked potentials and fMRI in a discrimination paradigm, we studied the changes in brain activity that are related to this change in perception. With ERPs, we observed that phonemic coding is faster than acoustic coding: The electrophysiological mismatch response (MMR) occurred earlier for a phonemic change than for an equivalent acoustic change. The MMR topography was also more asymmetric for a phonemic change than for an acoustic change. In fMRI, activations were also significantly asymmetric, favoring the left hemisphere in both perception modes. Furthermore, switching to the speech mode significantly enhanced activation in the posterior parts of the left superior gyrus and sulcus relative to the non-speech mode. When responses to a change of stimulus were studied, a cluster of voxels in the supramarginal gyrus was activated significantly more by a phonemic change than by an acoustic change.

It is related to the psychophysiological interaction technique introduced by Friston et al. and extends to networks of correlation modulation (CM networks). Extended networks containing several dozens of nodes are determined in which the links correspond to consistent correlation modulation across subjects. In addition, we assess inter-subject variability and determine networks in which the condition-dependent functional interactions can be explained by a subject-dependent variable. We applied the technique to data from a study on syntactical production in bilinguals and analysed functional interactions differentially across tasks (word reading or sentence production) and across languages. We find an extended network of consistent functional interaction modulation across tasks, whereas the network comparing languages shows fewer links. Interestingly, there is evidence for a specific network in which the differences in functional interaction across subjects can be explained by differences in the subjects' syntactical proficiency. Specifically, we find that regions, including ones that have previously been shown to be involved in syntax and in language production, such as the left inferior frontal gyrus, putamen, insula, precentral gyrus, as well as the supplementary motor area, are more functionally linked during sentence production in the second, compared with the first, language in syntactically more proficient bilinguals than in syntactically less proficient ones. Our approach extends conventional activation analyses to the notion of networks, emphasizing functional interactions between regions independently of whether or not they are activated. On the one hand, it gives rise to testable hypotheses and allows an interpretation of the results in terms of the previous literature, and on the other hand, it provides a basis for studying the structure of functional interactions as a whole, and hence represents a further step towards the notion of large-scale networks in functional imaging}, Doi = {10.1098/rstb.2005.1653}, pdf = {http://www.pallier.org/papers/Dodel_funcConnect_RoyalSoc_2005.pdf}, Owner = {chrplr}, Pii = {L3EXB2A5JW0JL1JD}, Pmid = {16087437}, Timestamp = {2006.02.02}, Url = {http://dx.doi.org/10.1098/rstb.2005.1653} } @Article{Dubois2005, Title = {Frequency-shift based detection of BMS contrast agents using SSFP: potential for MRA.}, Author = {Jessica Dubois and Franck Lethimonnier and Francoise Vaufrey and Philippe Robert and Denis Le Bihan}, Journal = {Magn Reson Imaging}, Year = {2005}, Month = {Apr}, Number = {3}, Pages = {453--462}, Volume = {23}, Abstract = {A novel mechanism of MRI contrast enhancement, based on the detection by a balanced steady-state free precession (SSFP) sequence of the proton resonance frequency shift induced by bulk magnetic susceptibility (BMS) contrast agents, was investigated.

In vitro, a 5-mM concentration in contrast agent induced a 20-Hz frequency shift, leading to a signal increase of 92\% for Dy-DOTA, and a 10-Hz frequency shift, leading to a signal increase of 58\% for Gd-DOTA at the reference frequency, taking into account the nonlinear SSFP signal response on frequency offset. The concept was then evaluated in vivo on anesthetized rabbits. Low doses of dysprosium-DOTA were injected in their vascular system, and imaging was performed at the level of neck vessels. Following a bolus injection, mean signal changes of 31\%, 20\% and 14\% were observed in the carotid arteries, the vertebral veins and the jugular veins, respectively. The bolus peak times in arteries and veins were consistent with the rabbit vascular circulation.

In adults, the N1 responses evoked by bodies and faces were similar in amplitude but differed slightly in latency. The voltage topography of N1 also differed in concordance with fMRI data showing that two distinct areas are involved in face and body perception. Distortion affected ERPs to faces and bodies similarly from N1 on, although the effect was significant earlier for bodies than for faces. These results suggest that fast processing of configural information is not specific to faces but it also occurs for bodies. In 3-month-old infants, distortion decreased the amplitude of P400 around 450 msec, showing no interaction with image category.

It is thought to result from the disruption or deafferentation of the Visual Word Form Area (VWFA), a region in the left lateral occipitotemporal sulcus activated whenever normal subjects are viewing alphabetic strings. Most pure alexic patients retain the ability to identify single letters, and develop a strategy of letter-by-letter (LBL) reading. We recently studied fMRI activations in LBL readers and clarified the underlying mechanisms. However, LBL reading is a dynamic process which may improve over months or years of practice, although the cerebral bases of this continuing improvement are currently unknown.

When studying the contrast between words and consonant strings, which may be taken as a correlate of LBL reading, we also found a general decrease, except for similar left frontal and parietal regions, which showed a significant increase.

To further explore the functional architecture of visual word recognition, we employed a subliminal priming method with functional magnetic resonance imaging (fMRI) during semantic judgments of words presented in two different Japanese scripts, Kanji and Kana. Each target word was preceded by a subliminal presentation of either the same or a different word, and in the same or a different script. Behaviorally, word repetition produced significant priming regardless of whether the words were presented in the same or different script. At the neural level, this cross-script priming was associated with repetition suppression in the left inferior temporal cortex anterior and dorsal to the visual word form area hypothesized for alphabetical writing systems, suggesting that cross-script convergence occurred at a semantic level. fMRI also evidenced a shared visual occipito-temporal activation for words in the two scripts, with slightly more mesial and right-predominant activation for Kanji and with greater occipital activation for Kana.

The model provides a synthesis of psychological refractory period and random-walk models of response time. It merely assumes that a task consists of three consecutive stages-perception, decision based on noisy integration of evidence, and response-and that the perceptual and motor stages can operate simultaneously with stages of another task, while the central decision process constitutes a bottleneck. We designed a number-comparison task that provided a thorough test of the model by allowing independent variations in number notation, numerical distance, response complexity, and temporal asynchrony relative to an interfering probe task of tone discrimination. The results revealed a parsing of the comparison task in which each variable affects only one stage. Numerical distance affects the integration process, which is the only step that cannot proceed in parallel and has a major contribution to response time variability.

We searched for the cerebral regions engaged in this dysfunction. METHOD: Differences in brain regional activity were examined by event-related functional magnetic regional imaging (fMRI) in a group of adolescents or young adults (n = 12) with childhood-onset obsessive-compulsive disorder (OCD), relative to healthy subjects. Subjects performed a conflict task involving the presentation of two consecutive and possibly conflicting prime and target numbers. Patients' image dataset was further analysed according to resistance or non-resistance to symptoms during the scans. RESULTS: Using volume correction based on a priori hypotheses, an exploratory analysis revealed that, within the prime-target repetition condition, the OCD subjects activated more than healthy subjects a subregion of the anterior cingulate gyrus and the left parietal lobe. Furthermore, compared with 'resistant' patients, the 'non-resistant' OCD subjects activated a bilateral network including the precuneus, pulvinar and paracentral lobules.

A systematic representation of the English lexicon based in psycholinguistic considerations has been put together in the database Wordnet in a long-term collaborative effort. We present here a quantitative study of the graph structure of Wordnet to understand the global organization of the lexicon. Semantic links follow power-law, scale-invariant behaviors typical of self-organizing networks. Polysemy (the ambiguity of an individual word) is one of the links in the semantic network, relating the different meanings of a common word. Polysemous links have a profound impact in the organization of the semantic graph, conforming it as a small world network, with clusters of high traffic (hubs) representing abstract concepts such as line, head, or circle. Our results show that: (i) Wordnet has global properties common to many self-organized systems, and (ii) polysemy organizes the semantic graph in a compact and categorical representation, in a way that may explain the ubiquity of polysemy across languages}, Doi = { }, pdf = {http://www.unicog.org/publications/sigman_lexicon_pnas.pdf}, Owner = {chrplr}, Pii = {99/3/1742}, Url = {http://dx.doi.org/10.1073/pnas.022341799} } @Article{simon.mangin.ea:topographical, Title = {Topographical layout of hand, eye, calculation and language related areas in the human parietal lobe}, Author = {Olivier Simon and Jean-François Mangin and Laurent Cohen and Denis LeBihan and Stanislas Dehaene}, Journal = {Neuron}, Year = {2002}, Pages = {475--487}, Volume = {33}, pdf = {http://www.unicog.org/publications/Simon_ParietalMap_Neuron2002.pdf}, } @Misc{dehaene-lambertz02:_les, Title = {Les sciences cognitives}, Author = {Ghislaine Dehaene-Lambertz}, Note = {Medecine \& Enfance, 23}, Year = {2002}, Pages = {111--118} } @Misc{dehaene-lambertz:_le, Title = {Le langage dans la première année de vie: nouvelles perspectives}, Author = {Ghislaine Dehaene-Lambertz and Brit van Ooijen}, Note = {Médecine et Enfance, 22, 293--299}, Year = {2002}, pdf = {http://www.unicog.org/publications/Dehaene-Lambertz_LgMat_Medenf2002.pdf}, } @Misc{naccache02:_la, Title = {La perception subliminale : un aperçu sur l'inconscient}, Author = {Lionel Naccache and Stanislas Dehaene}, Note = {Pour la Science, 302, 96--102}, Year = {2002}, pdf = {http://www.unicog.org/publications/Naccache 2002_La_perception_subliminale_Pour_la_Science.pdf}, } @Misc{Simon2002, Title = {L'organisation topographique du cortex pariétal: du singe à l'homme}, Author = {Oliver Simon and Stanislas Dehaene}, Note = {Médecine/Science, 18, 535--537.}, Year = {2002}, pdf = {http://www.unicog.org/publications/Simon2002_Lorgansation_topographique_MedecineScience.pdf}, Owner = {gs985873}, Timestamp = {2009.09.21} } @Book{dehaene:cognitive, Title = {The cognitive neuroscience of consciousness}, Author = {Stanislas Dehaene}, Editor = {Stanislas Dehaene}, Publisher = {The MIT Press}, Year = {2001}, Address = {Londres, Angleterre}, Edition = {2001} } @PhdThesis{pinel:identification, Title = {Identification et modulation paramétrique des réseaux cérébraux impliqués dans l'arithmétique mentale.

We observed strong long-range correlations in the distribution of oriented segments that extend over the whole visual field. We further show that a very simple geometric rule, cocircularity, predicts the arrangement of segments in natural scenes, and that different geometrical arrangements show relevant differences in their scaling properties.

We focus on one particular aspect of that variability: the precision of action potential timing. We show that for common models of noisy spike generation, elementary considerations imply that such variability is a function of the input, and can be made arbitrarily large or small by a suitable choice of inputs.

The models all include an implementation and simulation of an elementary reward mechanism. Their central hypothesis is that tentative rules of behavior, which are coded by clusters of active neurons in prefrontal cortex, are selected or rejected based on an evaluation by this reward signal, which may be conveyed, for instance, by the mesencephalic dopaminergic neurons with which the prefrontal cortex is densely interconnected. At the molecular level, the reward signal is postulated to be a neurotransmitter such as dopamine, which exerts a global modulatory action on prefrontal synaptic efficacies, either via volume transmission or via targeted synaptic triads. Negative reinforcement has the effect of destabilizing the currently active rule-coding clusters; subsequently, spontaneous activity varies again from one cluster to another, giving the organism the chance to discover and learn a new rule. Thus, reward signals function as effective selection signals that either maintain or suppress currently active prefrontal representations as a function of their current adequacy. Simulations of this variation-selection have successfully accounted for the main features of several major tasks that depend on prefrontal cortex integrity, such as the delayed-response test, the Wisconsin card sorting test, the Tower of London test and the Stroop test. For the more complex tasks, we have found it necessary to supplement the external reward input with a second mechanism that supplies an internal reward; it consists of an auto-evaluation loop which short-circuits the reward input from the exterior. This allows for an internal evaluation of covert motor intentions without actualizing them as behaviors, by simply testing them covertly by comparison with memorized former experiences. This element of architecture gives access to enhanced rates of learning via an elementary process of internal or covert mental simulation. We have recently applied these ideas to a new model, developed with M. Kerszberg, which hypothesizes that prefrontal cortex and its reward-related connections contribute crucially to conscious effortful tasks. This model distinguishes two main computational spaces within the human brain: a unique global workspace composed of distributed and heavily interconnected neurons with long-range axons, and a set of specialized and modular perceptual, motor, memory, evaluative and attentional processors. We postulate that workspace neurons are mobilized in effortful tasks for which the specialized processors do not suffice; they selectively mobilize or suppress, through descending connections, the contribution of specific processor neurons. In the course of task performance, workspace neurons become spontaneously co-activated, forming discrete though variable spatio-temporal patterns subject to modulation by vigilance signals and to selection by reward signals. A computer simulation of the Stroop task shows workspace activation to increase during acquisition of a novel task, effortful execution, and after errors. This model makes predictions concerning the spatio-temporal activation patterns during brain imaging of cognitive tasks, particularly concerning the conditions of activation of dorsolateral prefrontal cortex and anterior cingulate, their relation to reward mechanisms, and their specific reaction during error processing}, pdf = {http://www.unicog.org/publications/DehaeneChangeux_REWARD_ProgBrainRes2000.pdf}, Keywords = {Animals; Attention; Choice Behavior; Conflict (Psychology); Decision Making; Dopamine; Humans; Judgment; Learning; Models, Neurologi; Models, Psychological; Nerve Net; Neuronal Plasticity; Neuropsychological Tests; Prefrontal Cortex; Psychomotor Performance; Reinforcement (Psychology); Reward; Synaptic Transmission; cal}, Owner = {chrplr}, Pii = {S0079-6123(00)26016-0}, Pmid = {11105649}, Timestamp = {2007.06.27} } @Article{dehaene-lambertz:d, Title = {Le développement de la perception phonologique chez l'enfant : études électrophysiologiques}, Author = {Ghislaine Dehaene-Lambertz}, Journal = {Revue de Neuropsychologie}, Year = {2000}, Number = {4}, Pages = {519--533}, Volume = {10} } @Article{dehaene-lambertz.dupoux.ea:electrophysiological, Title = {Electrophysiological correlates of phonological processing : a cross-linguistic study}, Author = {Ghislaine Dehaene-Lambertz and Emmanuel Dupoux and A.

The hypothesis implies that only adults with a high level of verbal analytical ability will reach near-native competence in their second language, but that this ability will not be a significant predictor of success for childhood second language acquisition. A study with 57 adult Hungarian-speaking immigrants confirmed the hypothesis in the sense that very few adult immigrants scored within the range of child arrivals on a grammaticality judgment test, and that the few who did had high levels of verbal analytical ability; this ability was not a significant predictor for childhood arrivals. This study replicates the findings of Johnson and Newport (1989) and provides an explanation for the apparent exceptions in their study. These findings lead to a reconceptualization of the Critical Period Hypothesis: If the scope of this hypothesis is limited to implicit learning mechanisms, then it appears that there may be no exceptions to the age effects that the hypothesis seeks to explain}, pdf = {DeKeyser.robustness.critical.period.effects.ssa.2000.pdf}, Keywords = {critical period}, Owner = {chrplr}, Timestamp = {2007.02.12} } @Article{gisiger.dehaene.ea:computational, Title = {Computational models of association cortex}, Author = {T.

H., 1971. Neuropsychologia 9, 317-323.). Studies in the laboratory have shown, however, that perception of non-native speech sounds can be learned through training (Lively, S.E., Pisoni, D.B., Yamada, R.A., Tohkura, Y.I., Yamada, T., 1994. Journal of the Acoustical Society of America 96 (4), 2076-2087). This is consistent with neurophysiological evidence showing considerable experience-dependent plasticity in the brain at the first levels of sensory processing (Edeline, J.-M., Weinberger, N.M., 1993. Behavioral Neuroscience 107, 82-103; Merzenich, M.M., Sameshima, K., 1993. Current Opinion in Neurobiology 3, 187-196; Weinberger, N.M., 1993.

Outside of the laboratory, however, the situation seems to differ: we here report is study involving Spanish-Catalan bilingual subjects who have had the best opportunities to learn a new contrast but did not do it. Our study demonstrates a striking lack of behavioral plasticity: early and extensive exposure to a second language is not sufficient to attain the ultimate phonological competence of native speakers}, pdf = {http://www.pallier.org/papers/Pallier_catalan_spanish.pdf}, Keywords = {Analysis of Variance; Cross-Sectional Studies; Humans; Language Development; Multilingualism; Phonetics; Speech Perception}, Url = {http://www.pallier.org/papers/cognit_plast/webdata.htm} } @Article{pallier97c, Title = {Language-specific listening}, Author = {Pallier, Christophe and Christophe, Anne and Mehler, Jacques}, Journal = {Trends in Cognitive Science}, Year = {1997}, Number = {4}, Pages = {129-132}, Volume = {1}, pdf = {http://www.pallier.org/papers/Pallier_tics97.pdf}, } @Article{pallier97expe, Title = {{EXPE}: an expandable programming language for on-line psychological experiments}, Author = {Christophe Pallier and Emmanuel Dupoux and Xavier Jeannin}, Journal = brmic, Year = {1997}, Number = {3}, Pages = {322-327}, Volume = {29}, Abstract = {EXPE is a DOS program for the design and running of experiments that involve the presentation of audio or visual stimuli and the collection of on-line or off-line behavioral responses.

Subjects? responses are saved in a user-specified format, also in readable ASCII files. A remarkable feature of EXPE is that the user can easily add new commands to the language: all the instructions are calls to functions written in independent Borland Pascal units. Thus, users can link their own pascal procedures to EXPE to meet any special need.

Cette interrogation naît d'une découverte étonnante : notre cerveau est capable d'extraire une grande quantité d'information sur des stimuli extérieurs, même lorsque nous sommes incapables de rapporter explicitement leur présence. La perception pourrait donc fonctionner selon deux modes : conscient et non-conscient. Dans ce travail de thèse, nous avons tenté de préciser les relations entre ces deux modes de traitement perceptif en utilisant le protocole de clignement attentionnel (attentional blink), dans lequel on observe classiquement un déficit d'identification ou même de détection d'une cible visuelle qui est pourtant présentée au centre de notre champ visuel et pour des durées relativement longues. Dans une série d'expériences comportementales, nous avons demandé à des observateurs d'évaluer la visibilité d'une cible visuelle (un mot) sur une échelle continue. Bien que cette échelle offre la possibilité de rapporter des changements fins et graduels dans la perception de la cible, nous avons observé, dans la condition de clignement attentionnel, une dissociation entre deux types d'essais : pour des stimulations identiques, dans certains essais la cible était aussi bien perçue que lorsqu'elle était présentée en dehors du clignement attentionnel, tandis que dans les autres essais, les sujets utilisaient l'échelle comme si aucune cible n'avait été présentée. Ceci suggère que le traitement non-conscient ne correspond pas à une simple dégradation des même processus qui sont impliqués dans le traitement conscient. Ces résultats semblent plutôt indiquer l'existence d'une dynamique discontinue conduisant à l'accès à la conscience. Une étude d'électro-encéphalographie utilisant le même protocole nous a permis de préciser la dynamique temporelle des processus cérébraux sous-tendant la dissociation perceptive observée en comportement. Nous avons comparé, à stimulation identique, toute la séquence de potentiels cérébraux évoqués par le mot cible, selon qu'il était consciemment perçu ou non. Le traitement visuel précoce (P1, N1) était totalement préservé pour les cibles non-conscientes. Cependant, à la suite d'une période de transition rapide (entre 200 et 300 ms après la présentation de la cible), les cibles conscientes évoquaient une série de potentiels tardifs (N3, P3a, P3b), totalement absents pour des cibles non-conscientes. Nous proposons que l'accès à la conscience repose sur la mise en jeu optionnelle d'un réseau d'aires parieto-fronto-cingulaires permettant d'amplifier et de maintenir les représentations sensorielles et conceptuelles extraites du stimulus, et de mettre en communication des aires cérébrales éloignées. Ces mécanismes neurophysiologiques pourraient rendre compte des possibilités offertes par le traitement conscient qui se manifestent en comportement, depuis la possibilité de rapporter le stimulus jusqu'à l'utilisation stratégique des informations extraites de ce stimulus.} } @Article{cohen.bachoud-levi:role, Title = {The role of the output phonological buffer in the control of speech timing: A single case study}, Author = {Laurent Cohen and Anne Catherine Bachoud-Levi}, Journal = {Cortex}, Year = {1995}, Pages = {469--486}, Volume = {31} } @Article{cohen.dehaene:number, Title = {Number processing in pure alexia: the effect of hemispheric asymmetries and task demands}, Author = {Laurent Cohen and Stanislas Dehaene}, Journal = nc, Year = {1995}, Pages = {121--137}, Volume = {1}, pdf = {http://www.unicog.org/publications/cohen_number_puralex_neurocase_1995.pdf}, } @Article{cohen.dehaene:lecture, Title = {La lecture des nombres dans l'alexie pure: Effets de la tâche et de la spécialisation hémisphérique}, Author = {Laurent Cohen and Stanislas Dehaene}, Journal = rn, Year = {1995}, Pages = {480--485}, Volume = {151}, pdf = {http://www.unicog.org/publications/CohenL1995LalecturedesnombresRevNeurol.pdf}, } @Article{dehaene:electrophysiological, Title = {Electrophysiological evidence for category-specific word processing in the normal human brain}, Author = {Stanislas Dehaene}, Journal = {NeuroReport}, Year = {1995}, Pages = {2153--2157}, Volume = {6}, pdf = {http://www.unicog.org/publications/Dehaene_CategorySpecificERPs_NeuroReport1995.pdf}, } @Article{dehaene.akhavein:attention, Title = {Attention, automaticity, and levels of representation in number processing}, Author = {Stanislas Dehaene and R.

The present study investigated at what age infants become sensitive to language-specific phonotactic features that signal word boundaries and to what extent they are able to use this knowledge to segment speech input. Experiment 1 showed that infants at the age of 9 months were sensitive to the phonotactic structure of word boundaries when word-like units were presented in isolation. Experiments 2 to 5 demonstrated that this sensitivity was present even when critical items were presented in context, although only under certain conditions. Preferences for legal over illegal word boundary clusters were found when critical items were embedded in two identical syllables, keeping language processing requirements and attentional requirements low. Experiment 6 replicated the findings of Experiment 1. Experiment 7 was a low-pass-filtered version of Experiment 6 that left the prosody of the stimulus items intact while removing most of the distinctive phonotactic cues. As expected, no listening preference for legal over illegal word boundary clusters was found in this experiment. This clearly suggests that the preferential patterns observed can be attributed to the infants' sensitivity to phonotactic constraints on word boundaries in a given language and not to suprasegmental cues.}, Institution = {Institute für Psychologie, Freie Universität Berlin, Germany.}, Keywords = {Acoustic Stimulation; Age Factors; Contrast Sensitivity; Female; Humans; Infant; Language; Male; Phonetics; Speech Perception}, Owner = {pallier}, Pmid = {8414887}, Timestamp = {2008.12.31} } @Article{léger.levasseur.ea:slowly, Title = {Slowly progressive aphasia}, Author = {J.-M.

The model relies on hypothetical elementary devices made up of three neurons, the synaptic triads, which yield short-term modification of synaptic efficacy through heterosynaptic interactions, and on a local Hebbian learning rule. The functional units postulated are mutually inhibiting clusters of synergic neurons and bundles of synapses. Networks formalized on this basis display capacities for passive recognition and for production of temporal sequences that may include repetitions. Introduction of the learning rule leads to the differentiation of sequence-detecting neurons and to the stabilization of ongoing temporal sequences. A network architecture composed of three layers of neuronal clusters is shown to exhibit active recognition and learning of time sequences by selection: the network spontaneously produces prerepresentations that are selected according to their resonance with the input percepts. Predictions of the model are discussed}, pdf = {http://www.unicog.org/publications/DehaeneChangeuxNadal_NetworkTemporalSequencesBirdsong_PNAS1987.pdf}, Keywords = {Animals; Birds; Learning; Mathematics; Models, Neurological; Models, Psychological; Neurons; Synapses; Time Factors; Vocalization, Animal}, Owner = {chrplr}, Pmid = {3472233}, Timestamp = {2007.01.23} } @Misc{dehaene:comparing, Title = {Comparing numbers with a mental zoom}, Author = {Stanislas Dehaene}, Note = {Actes du congrés Cognitiva 87}, Year = {1987}, Pages = {144--149} } @Article{Mehler1986, Title = {[{D}iscrimination of the mother tongue by newborn infants]}, Author = {J.
