[Research on the epileptogenic complex].
The great importance of a correct definition of the lesional-functional epileptogenic complex for the surgical treatment of the epileptic patient is stressed. The means utilizable to reach the knowledge of the topographic organizatif the latters are descri0ed and discussed in detail: the scalp EEG, the examinations based on the EEG effects of endocarotid injection of barbiturates and convulsants, the EEG during nocturnal sleep, the direct recording of electrocerebral activity from the cortical surface (electro-corticography) and from deep cerebral structures (stereoelectro-encephalography). The relative importance of the informations provided by the electrical activity of "lesional" type, by the interictal epileptic activity and by the ictal one is analyzed. The utilization of methodologies of automatic elaboration of the electrocerebral signals is reminded. Finally, the different modes of application of the means of analysis mentioned above in the different epileptic patients are discussed and exemplified.
