title: Distinct dopaminergic systems in ACTH-induced grooming.
abstract: Excessive grooming behavior induced in rats by intraventricular injection of ACTH1-24 was inhibited by selective pharmacological manipulation of two functionally distinct types of dopaminergic terminals (DAe and DAi) in the neostriatum or the nucleus accumbens. It is concluded that when ACTH1-24 produces the behavioral response it modulates the activity of both the DAe and the DAi systems.
