    Researchers locate mechanism underlying plasticity in grownup brains

    Developing brains continuously sprout new neuronal connections called synapses as they understand and remember. Important connections — the ones that are repeatedly introduced, such as how to avoid danger — are nurtured and reinforced, while links deemed unnecessary are pruned away. Adult brains experience similar pruning, but it was unclear why or how synapses in

    Scientists portray regions of DNA that sway MECP2 expression

    Researchers at Baylor College of Medicine and the Jan and Dan Duncan Neurological Research Institute at Texas Children’s Hospital (NRI) have identified and characterized two regions of DNA required for the proper expression of Mecp2/MECP2 in mice and humans. These findings, published in Genes & Development, are helping to shed light on the purpose of
