Figure 3. Effects of antalarmin injected into the CeA on delay discounting, operant binge drinking, sucrose drinking.

(A) Both doses of antalarmin [N=6/dosage group] reduced operant responding for alcohol of MS rats compared to vehicle-treated MS rats [N=6]. (B) Both 2 and 4 μg doses of antalarmin [N=6/dosage group] microinjected into the CeA of MS rats elevated adjusted amount [decreased impulsivity] compared to vehicle treatment in MS rats [N=6]. (C) Both doses of antalarmin in the CeA [N=5/dosage group] did not alter the responding of MS rats for sucrose compared to vehicle [N=5]. * P ≤ 0.05 by ANOVA.
