FIGURE 2: Math-responsive network in blind and sighted mathematicians in experiment 1.
        Whole-brain inflated maps and one coronal slice showing the contrast of meaningful math 
        versus meaningful nonmath reflection in the group of sighted mathematicians (A), 
        the group of blind mathematicians (B), and each subject A (C), B (D) and C (E). 
        Contrast maps are presented with punc < 0.001 uncorrected at peak level, and 
        pFDR < 0.05 corrected for multiple comparisons at voxel lovel.



(A) Meaningful math > meaningful non-math in sighted mathematicians




(B) Meaningful math > meaningful nonmath in blinded mathematicians




(C) Meaningful math > meaningful nonmath in subject A




(D) Meaningful math > meaningful nonmath in subject B




(E) Meaningful math > meaningful nonmath in subject C

Figure 3. Math-responsive network in blind and sighted mathematicians in experiment 2. 
        Same format as figure 2 with whole-brain inflated maps and coronal slices showing the contrast 
        of math versus nonmath reflection 



(A) Math > nonmath in sighted mathematicians




(B) Math > nonmath in blinded mathematicians




(C) Math > nonmath in subject A




(D) Math > nonmath in subject B




(E) Math > nonmath in subject C

Figure 4. Additional occipital activation elicited by math in blind mathematicians.
        (A) Occipital coronal slices showing the interaction of group with math versus non-math statements 
        (Blind > Sighted mathematicians  x  math > nonmath statements) in experiment 1 (top panel) and
        experiment 2 (bottom panel).
