gamma-Hydroxybutyrate depresses monosynaptic excitatory and inhibitory postsynaptic potentials in rat hippocampal slices.

Abstract

The action of gamma-hydroxybutyrate was studied on pre- and postsynaptic GABA(B) receptors in rat hippocampal neurones in vitro using intracellular recording. gamma-Hydroxybutyrate (1-10 mM) caused a 4-8 mV hyperpolarization of CA1 cells and a 20-80% decrease in monosynaptic excitatory and inhibitory postsynaptic potentials in a concentration-dependent… (More)
