Chronic treatment with MK-801 (0.3 mg/kg ip; 5 weeks) reverses the deficit in rewarded behavior (anhedonia) measured as a decrease in the consumption of a palatable sucrose solution in a chronic mild stress model of depression in rats. The magnitude of this effect was comparable to that observed following similar administration of imipramine (10 mg/kg ip; 5 weeks), used as a standard antidepressant drug.
