The interaction between pimozide (a selective D2-dopamine receptor antagonist) and d-amphetamine on the operant performance of rats maintained under variable-interval schedules of positive reinforcement was examined. In Experiment 1, eight rats responded under variable-interval 30-s and variable-int

La d-amph6tamine inject6e I.

Dose-response curves were obtained for the effects of d-amphetamine sulphate (0.1-3.2 mg/kg) on the operant performance of rats in variable-interval 4-min and variableinterval 20-rain schedules of reinforcement. Response rates maintained under variable-interval 4-rain were suppressed in a dose-depen
External discriminative stimuli can modify the behavioral effects of d-amphetamine. Previous work with the pigeon has demonstrated that some aspects of performance on the fixed consecutive number schedule are changed less if a discriminative stimulus indicates when reinforcement is available. This e
Almost identical results are reported in man and in rat for the effects of the amphetamine isomers on polygraphically recorded sleep. In both species, dextro-amphetamine produces a significantly greater increase in waking time. In both species, the two isomers have equal effects in reducing desynchr
The effects of d-amphetamine sulphate on grooming, rearing, and ambulatory behaviour in the T-maze was studied in rats. Low doses (0.25-2.0 mg/kg) produced a dose-dependent change in behaviour; ambulatory behaviour was increased while grooming and rearing behaviour was decreased. The results suggest
