Summary

Story summary

A comprehensive study identifies five major brain development epochs from scans of nearly 4,000 individuals.
The study pinpoints turning points at ages 9, 32, 66, and 83.
Childhood development lasts through age nine, followed by an adolescent phase through 32.
From 32 onward, brain architecture stabilizes and intelligence and personality plateau.
Final turning points at 66 and 83 indicate connectivity declines linked to aging.
