It suggests that as sensory/unimodal regions and the default mode network grow structurally apart in adolescence, their functional coupling tends to fall. If it holds, it helps explain how the maturing wiring of the brain relates to the development of large-scale functional organisation.","findings":["Longitudinal analyses showed a continued differentiation of multiple corticocortical structural networks in youth.","At baseline, regions with more similar structural wiring were more likely to be functionally coupled.","Increased structural differentiation, particularly between sensory/unimodal and default mode networks, was reflected by reduced functional interactions over time."],"terms":[{"term":"structural differentiation","means":"The degree to which the wiring profiles of different brain networks become more distinct from one another."},{"term":"default mode network","means":"A set of brain regions that tends to be active during rest and inward-focused thought."},{"term":"functional connectivity","means":"The statistical correlation between activity in different brain regions over time, measured here with resting-state functional MRI."}],"basis":"abstract","abstractFrom":"crossref","model":"claude-sonnet-5-5","writtenAt":"2026-10-15T21:31:07.894Z","version":"context/0.2"},"summary":{"status":"written","at":"2026-10-15T21:31:07.894Z","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.
