Study Identifies Five Brain Development Phases and Key Turning Points Across Lifespan
A new study published in Nature Communications suggests the human brain develops through five distinct phases, with significant turning points around ages nine, 32, 66, and 83. Researchers from the University of Cambridge analyzed brain scans of nearly 4,000 individuals up to age 90. The study indicates that the adolescent phase extends to the early thirties, a period of 'ruthless efficiency' in neural networks. However, one article notes these findings are primarily applicable to Western populations, as cultural factors influence the transition to adulthood.
