Effects of co-infusion of 10 or 100 µM zacopride (a 5-HT3 receptor antagonist) with 150 mg% ethanol on lever responses for the intracranial self-infusion of ethanol into the nucleus accumbens shell (n = 6–7 / group). * p < 0.05, significantly higher responses than those on the inactive lever. # p < 0.05, significantly lower responses than the average responses on the active lever during acquisition sessions 3 and 4.
