During the past several years the authors have been engaged in the studies of the neuronal activities in the human epileptogenic foci. However, this is not, of cause, the sole way of the approach to the nature of the epileptogenesis. The combination of the physiology and the morphology is a dream of many workers. From this viewpoint electron microscopic studies were also made in some of these cases. Indeed there have been numerous reports concerning the histopathological studies of the epileptogenic foci. However, the electron microscopic findings combined with the results of extracellular unit study are extraordinarily rare. Therefore, it would be significant to present in this paper the details of the fine structures of the three human cortical epileptogenic foci.
