Chunk #21 — Mature Network Architecture Develops Via Segregation and Integration — Network Relationships Defined Using Region Matrix and Community Detection Methods
In contrast, task control regions show increased BOLD activity in a wide variety of tasks upon task initiation, with task maintenance, or with error commission (Dosenbach et al. 2006). Task control networks are also composed of a distributed set of regions and display correlated rs-fcMRI timecourses (Dosenbach et al. 2007). A fronto-parietal control network, which seems to be related to short-acting control like task instantiation and adjustment, includes regions in the precuneus, lateral inferior parietal sulcus, mid-cingulate cortex, and dorsolateral prefrontal cortex (depicted in yellow in Fig. 3). A cingulo-opercular network, which seems to be related to longer-acting task set instantiation and maintenance, includes regions in the anterior cingulate cortex, anterior prefrontal cortex, anterior insula/frontal operculum, and subcortical structures (shown in black in Fig. 3) (Dosenbach et al. 2006, 2007, 2008; Seeley et al. 2007).
