Abstract

Small rcgions of incrcascd electrical resistivity changes have been detected during spreading cortical dcpression (SCD) associated with seizures [1], Localization of these regions may be useful for finding the epileptic foci since it locatcs the region of SCD. Boone, Levi, and Holder [1] used electrical impedance tomography (EIT) with sub-dural electrodes and a transverse applied DC current to identify epileptic foci in a rabbit model. Since EIT is notoriously low in resolution, a technique of measuring electric impedance which gives greatcr resolution is desirablc. [2]
