[B] Number of lever presses of mice during the first 30 min session [N = 6] and the total responding after the entire 90 min session. Data are presented as mean ± SEM. Data were analyzed using repeated measures ANOVA with Dunnett’s post-hoc test. Pearson correlations were also performed. *, p < 0.01, compared to first 30 min session. **, positive correlation between BAC and responding for 1st 30 min session p < 0.03. †, positive correlation between BAC and responding after entire 90 min session, p < 0.05.
