Mean responses (±SEM) on the active and inactive lever by female Wistar rats for self-infusion of 200 mg% ethanol in the first four sessions, 200 mg% ethanol plus 10 μM (top, n=5), 100 μM (middle, n=8), or 200 μM GR 55562 (bottom, n=8) in sessions 5 and 6, and 200 mg% ethanol alone in session 7 into the p-VTA. Asterisks, responses on the active lever were significantly higher than responses on the inactive lever (p<0.05). There was no effect of co-administration of GR 55562 on lever responses for ethanol
