The necessity of metabotropic glutamate receptors (mGluRs) in the induction of long-term potentiation (LTP) has recently been questioned. We examined the effect of (R,S)-alpha-methyl-4-caboxyphenylglycine (MCPG), a selective mGluR antagonist, on two…
The mechanism of disinhibition produced by opioid peptides was studied using intracellular recording in area CA1 of rat hippocampal slices. The mu-selective opioid peptide [D-Ala2,N-Me-Phe4,Gly-ol5]-enkephalin (DAGO) reversibly depressed…
