Shown are data from the rats that completed the cue reactivity (n=15) and cue-induced reinstatement (n=37) paradigms. A. Cue reactivity. A two-way rmANOVA revealed no Treatment effect (F(3,44)=2.29), a significant Time effect (F(3,132)=13.46) with no Treatment x Time interaction (F(9,132)=1.92); three statistical outliers excluded from analysis. B. Cue-induced reinstatement. A two-way rmANOVA revealed no Treatment effect (F(3,44)=2.29) on inactive lever pressing. A significant Time effect was demonstrated (F(3,132)=13.46) with no Treatment x Time interaction (F(9,132)=1.92). Newman-Keuls post-hoc analysis indicated a significant decrease comparing 5.0mg/kg mirtazapine vs. vehicle in the first 15min of testing (*p<0.05); one statistical outlier removed from vehicle and 0.5mg/kg mirtazapine pretreated groups.
