Driving hub regions in the functional directed network of the human brain.

The driving hub regions (>mean+SD) in the human functional directed network are listed in a descending order of their out-degree . The regions are classified as primary, association, limbic, paralimbic and subcortical as described previously in [89]. IFGoperc, opercular part of the inferior frontal gyrus; ACG, anterior cingulate and paracingulate gyri; PUT, putamen; ORBinf, orbital part of the inferior frontal gyrus; INS, insula; ANG, angular gyrus; IFGtriang, triangular part of the inferior frontal gyrus; SMA, supplementary motor area; DCG, middle cingulate and paracingulate gyri; FFG, fusiform gyrus; L, left; R, right.
