- Neuroscientists at the University of Cambridge identified five broad phases of brain structure over a human lifespan.
- The study analyzed MRI diffusion scans of 3,802 people aged zero to 90, revealing four pivotal turning points in brain architecture.
- Major turning points occur at ages: 9 (Childhood), 32 (Adulthood), 66 (Early aging), and 83 (Late aging).
- Age 9: Brain transitions from infancy to childhood, with network consolidation and increased risk of mental health disorders.
- Age 32: Brain shifts into adult mode, reaching peak cognitive performance and stability for the next 30 years.
- Age 66: Marks the start of early aging, with gradual reorganization of brain networks and increased health risks.
- Age 83: Final phase where global brain connectivity declines, relying more on specific regions.
- Understanding these phases helps identify vulnerabilities in brain wiring linked to neurodevelopmental and neurological conditions.
