Antagonism of the discriminative stimulus and rate decreasing effects of pramipexole in rats trained to discriminate 0.1 mg/kg pramipexole from saline. Open symbols represent the administration of the dose of pramipexole indicated with a 30-min pretreatment of 1.0 mg/kg L-741,626 (squares), 32 mg/kg PG01037 (triangles), or 0.032 mg/kg haloperidol (inverted triangles). Open symbols above Veh represent data from the antagonist given as a pretreatment to a saline injection. Unless indicated on the graph, each treatment condition represents n=6
