In the experiments described in the present report, we evaluated the effects of ethanol on the activity of GABA(A) receptors of cerebellar granule cells in culture. Only very high ethanol concentrations (100-300 mM) showed a clear and significant stimulatory effect on the activity of such receptors. This result was unexpected. In fact, previous reports from other groups would have suggested high ethanol sensitivity of at least one population of GABA(A) receptors expressed by granule cells.

Abstract
In the experiments described in the present report, we evaluated the effects of ethanol on the activity of GABA(A) receptors of cerebellar granule cells in culture. Only very high ethanol concentrations (100-300 mM) showed a clear and significant stimulatory effect on the activity of such receptors. This result was unexpected. In fact, previous reports from other groups would have suggested high ethanol sensitivity of at least one population of GABA(A) receptors expressed by granule cells.
