Epileptic source localizations based on EEG and SDE measurements

Abstract

Epilepsy is one of the most common diseases related to the disfunctioning of the central nervous system. For the patients whose drug therapy turns out to be ineffective, it is a common method to identify the locations of sources that trigger the seizure in the brain tissue and resect them through surgical means for treatment. The success of the surgical operation depends on the accurate localization of the foci. Spatial location of the epileptic foci in the brain can be determined by solving the inverse problem using the EEG and SDE measurements. In this study, a source localization validation is performed using the surface and cortex electrical measurements of an epilepsy patient who has underwent a resection operation.
