Overview
- The study, reported in Nature Communications, analyzed brain connectivity in roughly 3,802 MRI scans from people aged 0 to 90.
- An extended reorganization phase runs from about age 9 to 32, with the strongest topological shift occurring around 32.
- Between 32 and 66 the brain shows a long period of relative stability before connectivity loss accelerates near 66.
- Around 83 the brain’s communication pattern shifts from more global integration toward greater local dependence, with limited data for this oldest group.
- Authors and external experts highlight potential uses for identifying ages of heightened vulnerability, while noting some media reports cite conflicting datasets or even a different journal.
