HT2A and 5-HT2C antagonists on the acquisition and expression of voluntary alcohol drinking. The 77 authors used a two-bottle choice paradigm to determine the role of the serotonin 5-HT2A and 5-78 HT2C receptors on alcohol consumption and preference during an acquisition phase and during re-79 exposure to ethanol after abstinence periods. Two independent experiments using adult Swiss male 80 mice as experimental subjects were performed, in which 5-HT2A and 5-HT2C antagonists (either 81 alone or combined) were administered either before acquisition (Experiment 1) or during the 82 abstinence period preceding re-exposure sessions (Experiment 2). The authors found that the 5-HT2A
