title: Self-stimulation responses are altered following long-term but not short-term treatment with clorgyline.
abstract: Clorgyline (a selective monoamine oxidase-inhibiting antidepressant) given chronically facilitated hypothalamic self-stimulation in rats, while acute treatment was without effect. Furthermore, long-term but not short-term clorgyline treatment significantly attenuated the suppressive effect of the selective alpha 2-adrenergic agonist clonidine on this behavior. These findings suggest that adaptative alterations in the modulation of rewarded behavior by inhibitory presynaptic noradrenergic receptors may be involved in antidepressant efficacy.
