Outline of Final Research Achievements

Epileptic focus identification based on new approach is necessary to the spread of epilepsy surgery. Dense array EEG, which is constructed to include electrode coverage over the face and neck, the purpose of which is to feasibly electrographically sample basal brain regions, is a method of recording electroencephalography (EEG) with many more electrodes (up to 256) . High frequency oscillations (HFO) near epileptic discharges from patients with intractable epilepsy were detected by the dense array EEG. Dense array EEG is helpful to understanding epileptic focus with analyzing HFO.
