abstract：:A range of selective dopamine D1 and D2 receptor agonists and antagonists was used to characterize to the discriminative stimuli produced by d-amphetamine (0.5mg/kg) and the D1 agonists SKF 81297 (0.1mg/kg). In rats trained to discriminate d-amphetamine (0.5mg/kg) from saline, d-amphetamine produced a dose-related inc...
