Increasing age is associated with reduced distinctions between RSFC-defined connector and non-connector nodes. A, Spring-embedded graphs depicting the community assignments of YA, ME, ML and OA at 4% edge density demonstrate that a collection of prominent functional systems is detectable in each age group. B, RSFC-defined connector status of nodes was classified within each age group relative to their affiliated system's median PC. C, Within systems, connector and non-connector nodes exhibit reduced differences in their PCs with increasing age (circles). D, Direct comparison of a node's PC (calculated across 2–10% edge densities) as a function of node type highlights significantly decreasing differences in connector versus non-connector nodes with increasing age. Error bars represent SEs.
