The effects of leptazol and bicuculline on the efflux of endogenous acetylcholine (ACh) from the surface of the cerebral cortex have been related to EEG activity in urethane-anaesthetised rats. During seizure activity there was a calcium dependent increase in ACh efflux which was related to increase EEG activity and clonic muscle movements. ACh release and EEG activity were reduced during convulsive activity by trimethadione but not phenytoin. Phenobarbitone reduced convulsive EEG activity but left ACh release relatively unaffected. Blood pressure changes induced by convulsant and anticonvulsant drugs were not consistently related to EEG activity or ACh release. It is suggested that ACh efflux from the cerebral cortex is closely related to the activity of neurones within the cortex where it is released from nerve endings. Comparison of EEG changes induced by anticonvulsants and urethane during control and convulsant activity showed that only trimethadione produces anticonvulsant activity unaccompanied by general CNS depression.
