rs-fcMRI is increasingly used to study the development of functional brain networks. Thus far, developmental studies of a number of brain networks including task control networks (Fair et al. 2007, 2009), the default mode network (Fair et al. 2008, 2009), and even whole brain anatomical networks (Supekar et al. 2009) indicate a general principle of anatomical segregation and functional integration whereby child networks are organized primarily by anatomical proximity, while adult networks are organized in a distributed manner across the brain.
