Ethanol self-administration in perinatal fat-exposed vs. chow-fed rats. Both fat-exposed and chow-fed rats fail to acquire ethanol self-administration (0.04 g/kg/infusion) after nicotine is removed from the solution, as demonstrated by a lack of escalation in the number of lever responses and infusions during a 14-day period under the FR1, FR2, and FR3 schedules of reinforcement (n = 11/group). *p < 0.05
