The effects of subcutaneous injection of dopamine D2 agonist quinpirole, in conjunction with central vasotocin (VT) infusion, on mate competition aggression (per 7 min session) in male zebra finches. Infusions of VT did not reverse the inhibitory effects of D2 agonist treatment on mate competition aggression: subcutaneous injection of 1 mg/kg of the D2 agonist + infusion of 50 ng VT into the lateral ventricle inhibited aggression in comparison to injection of 0.9% NaCl vehicle (VEH) + infusion of 50 ng VT or injection of VEH + infusion of VEH (n=21, p=0.036). Different letters above bars indicate treatment groups differing at α<0.05 in posthoc comparisons. Bars represent means + 1 S.E.M.
