The lasting effects of neuronal activity on brain development involve calcium-dependent gene expression. Using a strategy called transactivator trap, we cloned a calcium-responsive transactivator called CREST (for calcium-responsive transactivator). CREST is a SYT-related nuclear protein that interacts with adenosine 3',5'-monophosphate (cAMP) response(More)
Serine racemase (SR), localized to astrocytic glia that ensheathe synapses, converts L-serine to D-serine, an endogenous ligand of the NMDA receptor. We report the activation of SR by glutamate neurotransmission involving alpha-amino-3-hydroxy-5-methylisoxazole-4-propionic acid receptors via glutamate receptor interacting protein (GRIP) and the physiologic(More)
At weaning, mammals switch from drinking mother's milk to eating foods of environmental origin. These foods contain natural compounds with novel tastes and textures, which are provided to the young for the first time following the termination of breastfeeding. This novel eating experience may alter the cognitive brain function of mammalian babies,(More)
