  • Look Inside

An attempt was done in order to make an electro-physiological analysis of the Megimide-induced seizure by means of the depth EEG. Fractional administration of the Megimide solution (2.5mg/30sec) was given in unanaesthetized cats.

1. The minimum dosage of the Megimide inducing the major seizure, multiple spike discharge associated with convulsion, was 10.0mg/kg.

2. The excitation which was indicated by sharp waves or spikes in EEG was originated at the motor cortex. In contrast, the origination at the limbic struc-tures or subcorticobrainstem was found in none of the cases.

3. It is, therefore, to be concluded that the Megi-mide-induced seizure is of the cortical origin.

4. Based on these facts, the literatures concerning the clinical experiences of the Megimide provocation were reviewed with special reference to the comparison with Metrazol. An attention was stressed to pay the pharmacological potency and the mode of the seizure activation in the normal brain in case of drug acti-vation of the seizure in abnormal human brain.
