Summary of effects of (±)-methcathinone, (±)-MDPV, (±)-methylone and (±)-mephedrone on ICSS expressed as percent pre-drug baseline number of stimulations delivered across all frequencies of brain stimulation. Left panel (a) compares potencies and efficacies of drugs. Abscissa: drug dose in mg/kg. Ordinate: percent pre-drug baseline number of ICSS reinforcers. Right panel (b) compares time course profiles of drugs. Abscissa: pretreatment time in min. Ordinate: percent pre-drug baseline number of ICSS reinforcers.
