Figure 3. The concentration-response curve shows the ethanol-induced decrease in amplitude of the outward currents in cerebellar PCs.

The concentrations of ethanol at 50 mM (n = 6), 100 mM (n = 7), 300 mM (n = 18) and 500 mM (n = 9) were used to examine the effect of ethanol on the facial stimulation-evoked outward currents of PCs. The IC₅₀ value obtained from the curve was 148.5 mM. The number of the recorded PCs tested for each concentration indicated near the bars.
