Upper left panel: Responding on the MDPV-appropriate lever during sequential training sessions preceded by MDPV (filled circles) or saline (open circles) injections. Upper right panel: Percentage of rats that met the acquisition criteria as a function of the number of training sessions Lower left panel: Percent MDPV-appropriate responding (filled circles) and rate (filled squares) as functions of MDPV dose. Lower right panel: Percent MDPV-appropriate responding following injection of 1 mg/kg MDPV as a function of pretreatment time. All data are represented as the mean ±S.E.M with the exception of the survival plot.
