Glucagon-like peptide-1 modulates neuronal activity in the rat's hippocampus.

abstract：:Pharmacologically distinct NMDA-glutamate receptor subtypes have been reported in brain. We have studied the developmental expression of the mRNA encoding the NMDA receptor NR2C subunit in the rat brain by in situ hybridization. In contrast with the adult where no hybridization signal was detected in the hippocampus, ...
