Ethanol inhibited electrically stimulated [3H]ACh release from cortical brain slices, but not when release was stimulated by high potassium. In contrast, ethanol was ineffective on electrically stimulated release of GABA from cortical brain slices, but inhibited potassium-induced release. Ethanol also significantly inhibited potassium-stimulated [14C]GABA release from cortical synaptosomes. These data suggest that ethanol selectively inhibits GABA release from neurons by a specific effect on potassium conductance, and inhibits ACh release by a selective effect on Na+ conductance.
