Binge doses of methamphetamine (MA) cause brief epileptiform brain activity in about half of rats and longer seizures in some, while MDMA produces no significant brain-wave abnormalities or muscle jerks. The drug Foxy (5-MeO-DIPT) triggers seizures in all rats shortly after the first dose, with muscle jerks appearing soon after injection. These effects were observed in male rats implanted with cortical electrodes and given four injections of each drug (10 mg/kg every two hours), a regimen that mimics the neurochemical changes seen in chronic users. The findings indicate that MDMA does not increase EEG abnormalities under these conditions, whereas MA and especially Foxy produce severe brain-activity disturbances.
