Ethanol fails to increase the frequency of mIPSCs of CeA neurons in the presence of the selective BK channel blocker iberiotoxin. A, Traces show mIPSCs recorded from a CeA neuron during control, bath application of iberiotoxin alone, and coapplication of iberiotoxin and ethanol (50 mm). B, Interevent interval of mIPSCs was significantly decreased following bath application of iberiotoxin (*p < 0.05; n = 7), but ethanol does not alter mIPSC interevent intervals in the presence of iberiotoxin. C, There are no changes in the mean amplitude of mIPSCs after bath application of either iberiotoxin or iberiotoxin plus ethanol (p > 0.05).
