Study of the electrocerebral activity in partial epilepsies: its role for surgical treatment

Partial epilepsies, at least 90 percent of all epileptic syndromes, are the result of a localized abnormal brain hyperexcitability due to organic brain disease. The combination of the causal brain pathology and of the abnormally hyperexcitable neuronal population form what we have called the "lesional-functional epileptogenic complex.
