Abstract
(RS)-alpha-methyl-4-carboxyphenylglycine (MCPG), a compound which sele ctively antagonizes metabotrtopic glutamate receptors (mGlu-R), precen ts the LTP of field excitatory postsynaptic potentials (fEPSP) as well as the tetanus-induced increase in AMPA-evoked responses (fPRs) in th e CA1 region of hippocampal slices. This effects of MCPG provide evide nce for the involvement of mGlu-Rs in mechanisms underlying the postsy naptic maintenance of LTP, which appears to be mediated, at least part ially, by an increase in sensitivity and/or number of postsynaptic AMP A receptors.
