The presence of N-methyl-D-aspartate-type receptors for glutamic acid in the guinea pig myenteric plexus.

abstract：:Alterations in dendritic spine densities and morphologies have been correlated with the abnormal functioning of the synapse. Specifically the metabotropic glutamate receptor 5 (mGluR5) has been implicated in dendrogenesis and spineogenesis, since its activation triggers various signaling cascades that have been demons...
