The 39-node task control graphs of Fair et al, 2007. Fronto-parietal nodes are colored in yellow, and cingulo-opercular nodes are colored in black. Graphs are portrayed in a pseudo-anatomical layout at 10% edge density. (A-C) show graph structures in children ages 7–9 years, adolescents ages 10–15 years, and adults ages 19–31 years, respectively. Note the shifting associations of aPFC and dACC/msFC nodes, and the emergence of greater frontal-parietal functional connectivity over development. ROIs and node memberships were defined in (Dosenbach et al., 2006) and (Dosenbach et al., 2007). Figure modified from (Fair et al., 2007a).
