Aging pattern of network entropy in the human cerebral cortex. The fifteen large-scale networks of the cerebral cortex are employed to extract their mean entropy values (i.e., cortical network entropy) for trajectory modeling. Samples of each network entropy were separately fitted by GAMM, which estimated the aging curves for individual networks as indicated in the corresponding colors in the DU15NET cortical network parcellation. Accordingly, the rank of complexity level of the fifteen networks from five different ages (58, 64, 70, 76, and 82) were rendered as lateral and medial surfaces at the bottom
