To model chronic stress, rats were injected daily with yohimbine (0.0, 2.5, or 5.0 mg/kg; i.p.) during the first 7 days of extinction from palatable food self-administration. Injections were combined with SCH-23390 (0.0, 5.0, or 10.0 μg/kg; i.p.), a dopamine D1-like receptor antagonist. Rats were then tested for reinstatement of food seeking triggered by acute yohimbine (0.0, 1.0, or 2.0 mg/kg; i.p.) and pellet priming. Rats treated previously with chronic yohimbine displayed increased responding following acute yohimbine and pellet priming relative to non-chronically stressed rats under certain conditions. SCH-23390 combined with repeated yohimbine injections attenuated these effects.
