Five components of behavior elicited by dopamine (DA) agonists (locomotor hyperactivity, sniffing, oral activity, grooming and paw nibbling) were evaluated after bilateral infusion of the selective D1 agonist fenoldopam (SKF 82526; 2.5-10 micrograms), the selective D2 agonist quinpirole (LY 171555; 5-40 micrograms) and the muscarinic cholinergic antagonist… (More)
