Rats were trained and tested on a two-lever discrimination task based upon the presence or absence of 0.8 mg/kg d-amphetamine. After 80% criterion performance was attained, dopaminergic drugs reported to be effective in the treatment of Parkinson's disease were tested to investigate their ability to produce d-amphetamine-like responding. Amantidine (50 mg/kg), apomorphine (2.5 mg/kg), n-propylnoraporphine (0.1, 0.2 and 1.0 mg/kg), and piribedil (25 mg/kg) were all observed to produce d-amphetamine-appropriate responding. These results indicate that discriminative behavior controlled by d-amphetamine is mediated by central dopaminergic systems and the use of this technique in the evaluation of potential anti-Parkinsonism drugs is discussed.
