Interactions of GABA, bicuculline methochloride and diazepam with [3H]TBOB binding to rat brain membranes were evaluated in vitro. GABA displaced [3H]TBOB binding with and IC50 of 4 microM and a slope factor near unity. The competitive GABA antagonist bicuculline methochloride

Subunit composition of subsynaptic transmitter receptors is controlled presynaptically in the developing neuromuscular junction. To investigate presynaptic regulation of NMDA receptor subunit composition in the CNS, we co-cultured different types of hippocampal explants with dissociated target neurons. Postsynaptic NMDA receptors

Seasonal anestrus in ewes is driven by an increase in response to estradiol (E2) negative feedback. Compelling evidence indicates that inhibitory A15 dopaminergic (DA) neurons mediate the increased inhibitory actions of E2 in anestrus, but these neurons do not contain
