Enhancement of eIPSC amplitude of CeA neurons by ethanol was blocked in the presence of paxilline. A, Representative traces of eIPSCs at a holding potential of −70 mV before and after paxilline application and after coapplication with ethanol. B, Time course of the peak amplitude of eIPSCs during control, and bath application of paxilline and ethanol. C, Mean increase in the peak amplitude of eIPSCs after bath application of paxilline (n = 5, *p < 0.05); ethanol did not further change the amplitude of eIPSCs in the presence of paxilline.
