Abstract
Anatomical and functional data support a critical role for the bed nucleus of the stria terminalis (BNST) in the interaction between stress and alcohol/substance abuse. We report here that neurons of the dorsal anterolateral BNST respond to glutamatergic synaptic input in a synchronized way, such that an interpretable extracellular synaptic field potential can be readily measured. High-frequency stimulation of these glutamatergic inputs evoked NMDA receptor (NMDAR)-dependent long-term potentiation (LTP). We found that an early portion of this LTP is reduced by acute exposure to ethanol in a GABAAreceptor-dependent manner. This effect of ethanol is accompanied by a significant and reversible dose-dependent attenuation of isolated NMDAR signaling and is mimicked by incomplete NMDAR blockade.
