Two experiments investigated the dose and time related effects of morphine sulfate on the running wheel activity of golden Syrian hamsters. Compared with saline controls, a low dose (5 mg/kg) increased locomotor activity, whereas high doses (10, 20 and 40 mg/kg) produced an initial dose-related depression in activity, a gradual dose-related recovery and(More)
Two experiments investigated the dose and time related effects of morphine sulfate on wheel running behavior in golden Syrian hamsters. In Experiment 1, within-subject comparisons were made of the acute effects of 5, 20, and 40 mg/kg doses of morphine sulfate on running wheel activity. Compared with saline, morphine produced a dose related decrease in(More)
