Functional connectivity analyses of group data have revealed several large-scale distributed brain networks, including the default network (DN), frontoparietal control network (FPN) and dorsal attention network (dATN); however, few studies have examined network organization within individual subjects. The authors performed multiple functional MRI scans in four individuals and found that the DN, FPN and dATN could each be fractionated into two parallel and spatially juxtaposed, but dissociable, networks that were distributed across the cortex.
