Abstract
Functional connectivity is able to define brain networks that show intrinsic (i.e. task-independent) coordinated activity. Group-averaged network estimates correspond broadly to task-driven activity patterns. Recently, methods have been developed that allow precise network estimation within individuals. Here, we review recent observations which show that networks estimated within individuals can display a complex topology of regions that nonetheless shows close correspondence with task-driven activity patterns. The relationship holds across multiple networks and cognitive domains, and is evident in individuals that display atypical organization. The evidence hence supports that intrinsic fluctuations of brain activity are coordinated between functionally related sets of regions. We also highlight trends that emerge with increasing spatial resolution and discuss limitations of within-individual network estimation.
