Single Protein Rewires the Brain to Adapt to Motherhood

This shows a mom and baby.The presence of the MECP2 protein in parvalbumin (PV) neurons is crucial for newly-mothering mice to rapidly learn and respond to their pups’ distress cries, hinting at how the brain rewires during pivotal adult learning phases. When MECP2 is absent, maternal mice show neglectful behavior toward their young, illuminating how the protein’s dysfunction could contribute to communication and interpretation deficits in neurodevelopmental disorders like Rett syndrome in humans.
