CB1 activation prevented the ethanol-induced increase in GABAergic transmission in the CeA. A: Representative sIPSCs in control conditions, during WIN (2 µM) application and co-application of WIN and EtOH (44 mM) in CeA neurons from naive (left) and CIE (right) rats. B: WIN significantly (*p<0.05) decreased the mean sIPSC frequency in CeA neurons of naïve rats, but not CIE rats, and blocked the ethanol-induced increase in both groups. C: Representative mIPSCs in control conditions, during WIN application and co-application of WIN and EtOH in CeA neurons from naive (left) and CIE (right) rats D: WIN significantly (*p<0.05) decreased the mean mIPSC frequency in CeA neurons of naïve rats, but not CIE rats, and prevented the ethanol-induced increase in both groups. E: Representative sIPSCs in control conditions, during EtOH application and co-application of EtOH and WIN, in a CeA neuron from a naive rat. F: Acute ethanol significantly (*p<0.05) increased the mean sIPSC frequency in the CeA of both naïve and CIE rats, and the addition of WIN significantly (#p<0.05) decreased it to baseline levels.
