Group functional maps illustrate significantly greater responses to the multisensory audiovisual conditions compared to the sum of the responses for its unimodal constituents for both intact (a) and scrambled (b) stimuli. Significant differences were determined with paired t-tests, thresholded at z > 2.57 (p < 0.01, AFNI’s 3dttest + +, cluster-size correction α = 0.05 from 10000 Monte-Carlo simulations). The group functional topology comparisons are displayed on both left and right fiducial marmoset cortical surfaces, as well as on coronal slices. Regions are delineated by white lines, according to the Paxinos parcellation106 of the NIH marmoset brain atlas104.
