Surgery is a reliable treatment option1–6 for drug-resistant focal epilepsies associated with cortical structural lesions.7,8 When no lesion is detected with high resolution magnetic resonance (MR), or when the lesion extension cannot be outlined by neuroimaging,9,10additional intracerebral neurophysiological information is needed, in order to identify the brain area to be resected to achieve post-surgical seizure freedom.11 Stereo-electro-encephalography (Stereo-EEG) reveals intralesional and perilesional electrical activities, which define the Stereo-EEG identified Seizure Onset Zone (SEEG-SOZ) and its network.
