A. The volumes of the language fROIs (defined by the Sentence > Nonwords contrast) and gesture fROIs (defined by the Gesture > Grooming contrast) within the six language parcels (Figure 2, left). Dots correspond to responses of individual participants. B. The number of subjects showing different amounts of overlap (as quantified by the Jaccard index, i.e., the number of voxels that overlap between language and gesture regions divided by the total number of voxels for both contrasts, multiplied by 100)) between language- and gesture-responsive voxels, significant at the whole-brain threshold level of p < 0.001, within the language parcels (mean overlap across subjects across parcels = 3%, SD =4%)
