The claim draws together two patterns from the review: structural hubs appear early and keep a consistent location, while functional hubs shift from primary areas to association areas over development. It suggests that having the physical wiring in place does not mean a region can yet integrate information well. If it holds, it matters for understanding how brain function matures through childhood and adolescence.","findings":["Structural hubs appear to arise prenatally and keep a consistent spatial pattern, but consolidate over a long period extending into late adolescence.","Functional hubs show a more variable topography, mostly in primary cortical areas early in development, then moving to association areas by late childhood.","Not all findings agree with this view, and methodological factors may explain some of the inconsistencies."],"terms":[{"term":"network hubs","means":"Brain regions that are highly connected and play a central role in integrating activity across the brain."},{"term":"anatomical infrastructure","means":"The physical wiring of the brain, meaning the structural connections between regions."},{"term":"postnatal maturation","means":"Changes in the brain's structure and function that continue after birth."}],"basis":"abstract","abstractFrom":"europepmc","model":"claude-sonnet-5-5","writtenAt":"2026-10-11T18:02:02.535Z","version":"context/0.2"},"summary":{"status":"written","at":"2026-10-11T18:02:02.535Z","attempts":1,"model":"claude-sonnet-5-5","why":null},"note":"Machine-written context to help a reader: it is not evidence, it moves no number, and it may be wrong.
