abstract：:The central nervous system has extraordinary plasticity in early life. This is thought to involve N-methyl-D-aspartate (NMDA) receptors which, along with the non-NMDA receptors, mediate fast excitatory synaptic transmission. Although NMDA receptors may be transiently enhanced early in life, it has not been possible to...
