NEUROSPIN is looking for a post-doctoral researcher to study infants’ and adults’ brain with Optically Pumped Magnetometers
Join the Cognitive Neuro-Imaging Unit (www.unicog.org) at NeuroSpin brain imaging center.
This collaborative project is headed by Ghislaine Dehaene-Lambertz and gathers NeuroSpin and CEA Leti in Grenoble. The primary objective of this project is to determine the advantages of He4 Optically Pumped Magnetometers (OPMs) with respect to SQUID based standard MEG.
Optically pumped magnetometers are ultra-sensitive magnetic field detectors. Contrary to SQUIDs, which have to be cooled down with liquid helium, they can operate at room temperature. As a result, they can be placed at the surface of the scalp on an adaptable cap. CEA LETI has been developing OPMs based on He4 metastable atoms. A prototype of this OPM-based MEG with 5 sensors is currently being tested.
Eligible qualifications for this position include:
- Ph.D. in Physics, Engineering, Cognitive neuroscience, or related discipline
- Thorough knowledge of the technical, theoretical and practical principles of M/EEG, and expertise in signal processing.
- Fluent knowledge in computer programming (languages: Python, Matlab)
- Knowledge of cognitive neuroscience
Knowledge of the French language is not required, but would be a bonus.
The position is funded for one year and would start around November 1, 2021. The post-doctoral student will work in the laboratory of Prof. Stanislas Dehaene at NeuroSpin, in coordination with the MEG team. The main tasks associated with this job proposal are MEG/MEG-OPM data acquisition and processing with MNE-Python.
To apply, please submit a CV and a cover letter explaining how your previous research experiences are relevant to this project. These documents should be complemented with reference letters and sent to email@example.com with “OPMs at NeuroSpin” in the head of the e-mail.
NeuroSpin is France’s most advanced brain-imaging center. The whole building is dedicated to the understanding of the human brain and to the development of brain imaging technologies. Five laboratories currently share their expertise on site and provide a stimulating research environment. NeuroSpin hosts 8 state-of-the-art neuroimaging systems including 3 human MRIs (3T, 7T, and soon a world-record 11.7 Tesla), 3 animal MRIs (7T, 11.7T and 17.T), an MEG system, and a 3-photon imaging system. The MEG machine is a 306-channel system (Neuromag/Elekta) typically paired with EEG (native + EGI) and eye-tracking (Eyelink 1000 SR Research).
Thanks to powerful computational resources, NeuroSpin teams develop advanced post-processing tools for structural image processing (BrainVisa), fMRI data analysis (Nipy, Nilearn), diffusion imaging (Connectomist), and M/EEG analysis (MNE Python).

Extended-Personal Reality: augmented recording and transmission of virtual senses through artificial-intelligence
Social media has transformed the way we communicate through text, images, and videos. Despite recent technological avenues, virtual reality (VR) has not been incorporated in social platforms, hence limiting the comprehensive sharing of an experience. This project makes real the complex interplay between multisensory perception, emotional responses, past experiences, and perspective of the future also by disentangling the mental representation of self in space and time. The new Extended-Personal Reality technological and scientific paradigms will move Europe to the future generation of extended social interactions by allowing the public at large to i) create their own VR environments as they do photos and videos without the need for technical skills, ii) create virtual simulations eliciting unique psychological, cognitive, neurophysiological, and behavioural responses, iii) automatically generate VR environments from neurophysiological data, iv) easily manipulate VR environments to communicate and elicit specific emotions, v) manipulate perceived reality to effectively treat psychiatric disorders. EXPERIENCE embeds advanced artificial intelligence routines merging information from a person’s Extended-Personal Reality to inform manipulation tools including neuromodulation, multisensory biofeedback (audio, video, haptics), and subjective perception of time-space. EXPERIENCE will produce extremely realistic reproductions of the user’s past and may re-administer it by modulating the associated emotional states on demand. Within a large number of research and innovation avenues, EXPERIENCE will prioritise novel diagnosis and treatment of affective disorders commonly associated with altered multisensory perception like depression, anxiety, and eating disorders. A plethora of innovative technological paradigms including gaming, e-learning, and neuroeconomics will be in the commercial exploitations, including the opening of a new market for actually selling EXPERIENCEs.

Within the EXPERIENCE consortium, the goal of the scientific foundation for extended-personal reality work package is to investigate the functional correlates of known and novel temporal illusions in perception and cognition. The interferences between time and space, both at low-levels (e.g. kappa effect, temporal dilation; Project 1) and higher levels (e.g. mental distances; Project 2) are of particular interest in this project.
Both projects will use human psychophysics, VR, physiological recordings (EKG, GSR) and time-resolved neuroimaging techniques (MEG, EEG). State-of-the-art statistical techniques will be used to assess oscillatory coupling in brain activity as well as decoding and machine learning techniques.

Spatiotemporal Interferences in Prospective and Retrospective Experiences of Time
The human spatial navigation system (the so-called ‘GPS’ of the brain) encompasses hippocampal brain structures and provides a flexible internal mapping of a subject’s spatial position with respect to its environmental landmarks. These structures are involved in spatial navigation and episodic memory. However, very little is known regarding how time is perceived during navigation and episodic encoding: are temporal experiences (e.g. order, duration, speed) compressed in memory like any other informational content? Is time lost and reconstructed a posteriori? Does this reconstruction also support our experience of time in real-time? We will bring temporal distortions to VR, explore spatio-temporal interferences and see how they affect mental mapping.
