Adolescence Last into Your 30s and Other Brain Surprises
The human brain has four distinct turning points where its structure changes, according to a study published in the journal Nature Communications, demonstrating that brain development is not as linear as you might think.
"It's easy to fall into this belief that there’s a ‘good’ or ‘bad’ way for a brain to be structured," said lead study author Alexa Mousley at the University of Cambridge. "And that's not really the case. What this study is emphasizing is the brain is expected to be doing something different at different ages."
In the new study, Mousley and colleagues looked at around 4,000 scans from healthy people ages 0 to 90 and analyzed their brains. They found four major times when the brain underwent developmental changes, around ages nine, 32, 66 and 83, dividing the lifespan into five distinct phases.
