If it holds, differences in regional dynamics may partly reflect each region's role in the wider network.","findings":["Longer timescales are associated with greater within-community functional connectivity and diverse structural connectivity.","The study replicates a prior positive correlation between timescales and structural connectivity degree.","Functional connectivity is preferentially stronger between cortical areas with similar timescales, and the findings replicate in an independent dataset."],"terms":[{"term":"timescale","means":"The characteristic period over which a region's activity fluctuates during quiet rest, with longer timescales meaning slower-changing activity."},{"term":"community structure","means":"The division of a network into groups of regions that are more densely connected to each other than to regions outside the group."},{"term":"within-community functional connectivity","means":"The degree to which a region's activity is correlated with that of other regions in the same community."}],"basis":"abstract","abstractFrom":"crossref","model":"claude-sonnet-5-5","writtenAt":"2026-10-20T11:30:58.414Z","version":"context/0.2"},"summary":{"status":"written","at":"2026-10-20T11:30:58.414Z","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.
