[Variability of seizure phenomenology in the light of stereo-EEG studies].

The demonstration of a largely stable electroclinical semiology in the early phase of seizures is a main prerequisite for successful causative surgery of epilepsy. A few experiences with analysis of similarities during seizures are presented and discussed regarding their fundamental pathogenetic but also practical clinical significance. The primary data stem from candidates for selective surgery of the temporal lobe, mainly afflicted by psychomotor seizures. These seizures were recorded either by invasive stereoelectroencephalography or by semi-invasive foramen ovale electrodes.
