Puberty, Pregnancy, and Menopause Show Distinct Patterns of Brain Plasticity

A new brain imaging study shows that puberty and pregnancy are associated with widespread reductions in gray matter in the female brain, while the menopausal transition coincides with a surprising pause in typical age-related brain changes. The findings indicate that each of these reproductive life stages shapes the brain through a distinct pattern of plasticity, highlighting how hormonal transitions leave measurable structural traces across a woman's lifespan.
