A, B. The charge transfer and peak frequency of sIPSCs were not potentiated until EtOH was applied (paired t-tests *P <0.05, n = 5). C. EtOH potentiation of sIPSC charge transfer with different EtOH incubation times (unpaired t-tests *P <0.05, n = 4 for 0, 60 s conditions, n = 10 for 210 s condition). D. When a second mCPBG application was given at different time points after EtOH exposure, the potentiation of the mCPBG response was smaller at longer EtOH wash-out times (unpaired t-tests *P <0.05, **P <0.001, n = 6 for 90s condition, n = 9 for other conditions). E, F. The charge transfer and peak frequency of sIPSC responses to high K+ were not potentiated by EtOH exposure (n = 5).
