Abstract

We investigated the effect of GABA, muscimol and THIP on the K+ -stimulated and spontaneous release of [3H]GABA from neuron-enriched cell cultures of the rat cerebellum. Each agonist produced significant reductions in evoked [3H]GABA without causing marked changes in spontaneous release. The agonist-induced inhibition of K+ -stimulated [3H]GABA release was reversed by the GABA antagonists bicuculline and picrotoxin. It is suggested that GABAergic neurons in cerebellar cell cultures possess GABA receptors which are involved in the regulation of evoked transmitter release.
