A. Representative waveforms of sIPSCs in response to 10 μM mCPBG before, during and after washout of 80 mM EtOH. Scale bar = 400 pA, 10 s. B. Plots of sIPSC frequency (paired t-tests *P < 0.05, n = 6). C. EtOH potentiation of sIPSC charge transfer and peak frequency was maintained even after EtOH washout (paired t-tests *P < 0.05, n = 6). D. EtOH increases the charge transfer of sIPSC responses to mCPBG in a concentration-dependent manner. The post-EtOH-washout potentiation was also more distinct with higher EtOH concentrations. (paired t-tests *P < 0.05, n = 9, 9, 8 and 6 for 10, 20, 40 and 80 mM EtOH, respectively).
