摘要: The objective of this study was to determine the validity interictal spike (IIS) source localization in temporal lobe epilepsies (TLE) using stereoelectroencephalography as a validating method. Twenty patients with drug-resistant TLE were studied high-resolution EEG and stereoelectroencephalography. Sixty-four scalp channels, realistic head model, different algorithms used. For each patient, intracerebral distribution classified into one three groups: L (mainly lateral), ML (mediolateral), M (medial). In group (three patients), surface IIS recorded high signal-to-noise ratio. Source localizations designated all or part distribution. (11 8 had IIS, only 5 which localizable. High-resolution permitted more lateral portion definition its rostrocaudal extension. A common pattern identified predominant role pole.
