up of lateral frontal-parietal nodes;28 the salience network, an anterior cingulate/frontoinsular system with links to limbic and subcortical autonomic control centers,28 a dorsal attentional system embedded in high frontoparietal sensorimotor association regions,29 and networks related to primary visual, auditory, and sensorimotor regions.26 One area of active work concerns how many brain networks can be meaningfully outlined at the group and single-subject levels with these methods.
