Brain changes from childhood to young adulthood
Supekar et al. compare large scale brain functional networks in 7-9 and 19-22 year olds and find that they differ significantly in hierarchical organization and interregional connectivity. Subcortical areas are more strongly connected with primary sensory, association, and paralimbic areas in children, whereas young-adults show stronger cortico-cortical connectivity between paralimbic, limbic, and association areas.
