Steps in processing the gyrification-based networks. a Surface reconstruction was carried out using FreeSurfer software; local gyrification indices were estimated using Schaer’s procedure. b Destrieux atlas was used for parcellating the cortical surface to 148 regions (74 on each hemisphere). c Association matrices were obtained by calculating the correlations between regional gyrification across subjects within each group separately. d Binary adjacency matrices were derived from thresholding at minimum density for fully connected graphs in both groups
