Fatherhood Rewires with Active Care

Neuroscience scans of new fathers (Darby Saxbe's lab) suggest measurable brain changes that accompany a modern three‑fold increase in time fathers spend caregiving. Those paired behavioral and neural shifts imply fatherhood is not merely social role change but a biological plasticity response to caregiving. — If fathering reshapes male brains and time budgets at scale, it affects workplace norms, parental‑leave policy, child development outcomes, and debates about gendered caregiving responsibilities.
