HD-DOT system and study Design. A. HD-DOT array on a school-age participant. B. The field of view of the HD-DOT system on the cortical surface. C. The DOT field of view, broken into parcels based on the Gordon parcellation, included 141 unique parcels and sampled auditory, cingulo-opercular (CinguloOperc), default mode, dorsal attention (DorsalAttn), frontal parietal (FrontoParietal), somatosensory hand (SMhand), somatosensory mouth (SMmouth), ventral attention (VentralAttn), visual, and no-assignment (None) functional networks. D. The study design of the biological motion perception experiment, participants passively viewed point-light displays of coherent biological and scrambled motion separately through a 20-inch (diagonal) LCD monitor.
