Abstract

The rationale of surgical treatment of partial epilepsy is based on a series of different criteria. One of them is the information given by the study of electrocerebral signals on the development of the epileptic process and, in particular, on the topographic location of the lesional-functional epileptogenic complex (see Rossi et al. 1974, for an extensive review on the subject). Actually, there are patients in whom such a location can be defined only on the basis of the analysis of brain electrical activity which therefore becomes a factor of paramount importance for a reliable surgical indication. The use of depth electrodes—or stereoelectroencephalography (Bancaud et al. 1965)—is of substantial help in this connection. The experience accumulated in the last twenty years has brought a large convergence of opinion on the general principles, or tactical considerations, which are the basis of an stereoelectroencephalographic exploration of an epileptic patient regarded as a possible candidate for surgical treatment (Bancaud et al. 1965 and 1973; Talairach et al. 1974; Crandall 1973; Walter 1973; Rossi 1973; Rossi et al. 1974). However, in our opinion, a particular point deserves further discussion, namely the importance of the duration of the stereoelectroencephalographic exploration in order to obtain sufficient and reliable information. Our personal experience indicates that, in most cases, such a goal can be reached only, or can be greatly facilitated by utilizing prolonged and repeated recording, requiring “chronically” implanted intracerebral electrodes. The following findings illustrate our views.
