Fig. 1.

Illustration of the ROIs within the (A) ECN, (B) DMN, and (C) BGN. A total of 23 major ROI of the three networks are shown for a better presentation of the connections (i.e., edges) between these core nodes in each network without showing the left and right crus I of the ECN, the right lobule IX of the DMN, and the pons of the BGN. Images are displayed according to neurological convention; therefore, the right hemisphere corresponds to the right side in axial displays. Abbreviations: ROI, region of interest; OFG, orbitofrontal gyrus; SFG, superior frontal gyrus; MFG, middle frontal gyrus; CAU, caudate; THA, thalamus; MTG, middle temporal gyrus; AG, angular gyrus; PHG, parahippocampal gyrus; PCC, posterior cingulate cortex; PCUN, precuneus; MOG, middle occipital gyrus; IFG, inferior frontal gyrus; PUT, putamen; L, left; R, right.
