Effects of vehicle (white symbols) or ketamine (1 and 3 mg/kg; gray and black symbols, respectively) on the discriminative stimulus and response rate effects of methamphetamine (0.1-1.0 mg/kg). Data reflect the mean (±SEM) percentage of responses occurring on the methamphetamine-appropriate lever (upper panels), or the mean (±SEM) percentage of vehicle response rates (lower panels), as a function of methamphetamine dose. Data points reflect the average effects obtained in rats (n=6) trained to discriminate 1.0 mg/kg of methamphetamine from saline.
