They built individual network maps from 60 minutes of motion-censored data per participant using template matching.","gist":"Using an hour of video-viewing fMRI per person from 24 parent-child pairs, the study mapped individual brain networks and compared them across ages, finding broadly shared layout but weaker connectivity in children.","meaning":"The claim describes how similar children's and adults' brain networks look once each person's own map is used. It suggests that the basic layout and size of large networks are already largely adult-like by ages 6–8. The lower assignment confidence in children means their brain regions fitted the network templates less clearly. This matters for developmental research, since group-averaged maps may blur differences between individuals.","findings":["Network-level surface area showed no age effects, and few age differences were seen in network boundaries.","Children generally had lower confidence in how their brain regions were assigned to networks.","All approaches showed greater within-network connectivity in adults, with larger age effects and lower sensitivity to head motion when networks were individualised."],"terms":[{"term":"network-level surface area","means":"The total amount of cortical surface assigned to each large-scale brain network."},{"term":"network boundaries","means":"The edges on the brain's surface where one functional network gives way to another."},{"term":"assignment confidence","means":"How strongly a brain region's activity pattern matches the network it was assigned to, compared with other networks."}],"basis":"abstract","abstractFrom":"crossref","model":"claude-sonnet-5-5","writtenAt":"2026-10-24T23:16:28.517Z","version":"context/0.2"},"summary":{"status":"written","at":"2026-10-24T23:16:28.517Z","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.
