In a Y-maze exploratory task mice tend to enter that compartment which was least recently visited (spontaneous alternation). Low doses of d-amphetamine (1.0 mg/kg) reduce alternation to chance levels, while high doses (10.0 mg/kg) result in animals successively visiting only two compartments of the Y-maze (perseveration). Following daily d-amphetamine injection (1.0 or 10.0 mg/kg) over a 30 day period tolerance to the d-amphetamine induced perseveration was observed; however, chronic amphetamine treatment did not modify the locomotor stimulating effects of d-amphetamine or the reduction of alternation to chance levels produced by low doses of the drug. It was hypothesized that tolerance to d-amphetamine occurs exclusively to behaviors mediated by norepinephrine.
