Figure 3. Female 118AA and 118GG and Male 118GG mice develop a conditioned place preference (CPP) to the rewarding effects of 2 g/kg of ethanol.
The rewarding effects of 2 g/kg of ethanol were assessed in male and female mice using CPP. The amount of time (seconds) mice spent on the ethanol-paired side both prior to (pre; open bars) and after (post; black bars) ethanol conditioning is shown. Female 118AA (AA; N=8) and 118GG (GG; N=8) and male 118GG (N=8) mice spent more time (in seconds) in the ethanol vs. saline-paired conditioning chamber. In contrast, male 118AA (N=8) mice failed to develop an ethanol CPP. Error bars represent the standard error of the mean (SEM). * = p < 0.001 between pre and post conditioning sessions.
