Muscimol, 0.25-1.0 mg/kg, i.v., was administered acutely to 4 adolescent baboons, Papio papio, that show photically induced epilepsy. On the EEG, slowing of background rhythms was associated with the appearance of spikes, polyspikes, and recurring symmetrical spike-wave complexes. These changes were maximal 0.5-2 hr after muscimol injection. Regular testing with intermittent light stimulation showed either no change from control responses or a more severe epileptiform EEG 0.1-3 hr after muscimol. Photically induced myoclonus was not modified by muscimol. Despite its GABA-abonist properties, muscimol is not an effective anticonvulsant.
