Effects of GABAA antagonists on the discriminative stimulus and response rate effects of methamphetamine (1 mg/kg, i.p.). Left panels show the effects of pentylenetetrazol and bicuculline alone. The right panels show the effects of pentylenetetrazol (10 mg/kg, i.p.) and bicuculline (2.5 mg/kg, i.p.) in combination with increasing doses of methamphetamine (01. to 1 mg/kg, i.p.). Each point shows the average of 10 rats unless otherwise shown. Error bars show standard error of the mean. (+)-Meth indicates the methamphetamine control.
