This research shows that early-life oxytocin treatment can reverse key features of fragile X syndrome in mice. Brief intervention strengthens neural connections, normalizes learning and social behavior, and prevents seizures into adulthood. The findings suggest oxytocin may offer a safe, early intervention strategy for fragile X and other intellectual disabilities.

This research explores how chronic stress reshapes the brain through genetic mechanisms. By studying the stress-regulating gene MeCP2 in mice, the work shows how early-life stress can lock the brain into a heightened anxiety state, revealing biological pathways that may inform future treatments for stress-related mental health disorders.
