[EEG findings following cerebral surgery]

Departing from the well-known influences exerted on the picture of the cerebral potential by an intracranial space-occupying process, the persisting pathological EEG findings with proved absence of recidivity have been determined in this study. These investigations were based on the postoperative EEG leads of 204 patients with cerebral operations with a determination of the persisting focal disturbances, the general changes and the signs of an increased tendency to attacks and, with respect to possible consequences, a correlation with the morphological criteria-position and size of defect of the cerebral parenchyma, the extent of the cerebral ventricles, the histological dignity-being carried out.
