DR2/3/4 antagonist, raclopride (10 μM) had no effect on control γ power (4.2 ± 6.7% change, P > 0.05 vs. baseline, n = 11, Figures 2C,D). Raclopride did not change the suppressing effect of 50 mM ethanol (38.8 ± 4.6% decrease, P > 0.05 vs. that of 50 mM ethanol alone, n = 8, Figure 2D), or 100 mM ethanol (58.3 ± 5.9% decrease, P > 0.05 vs. that of 100 mM ethanol, n = 8; Figure 2D).
