Overview
- The largest structural reconfiguration appears around age 32, marking a move from youthful flexibility to a stable adult network layout.
- During adolescence, neural efficiency increases with faster, more refined communication across brain networks.
- From roughly the early 30s to the mid‑60s, the brain’s architecture shows a prolonged plateau before changes linked to modularization emerge.
- A late‑life shift near 83 indicates reduced global connectivity and greater reliance on local circuits, though data at this age are relatively sparse.
- The Cambridge analysis, published in Nature Communications and based on diffusion MRI from 3,802 people, suggests windows of vulnerability relevant to learning difficulties and dementia and underscores the need for longitudinal studies.
