Localizing epileptogenic zones with high-frequency oscillations and directed connectivity

Epilepsy is a serious, chronic neurological disorder that disrupts the normal activity of neurons in the brain. During seizure onset, the patient may be injured or even in a life-threatening emergency, which brings great psychological pressure and difficulties in work and life to the patient. For patients with drug-resistant epilepsy, epilepsy surgery can effectively treat seizures. The epileptogenic zone (EZ) is defined as the brain region in which the seizure is generated.[1,2] Generally, the evaluation of EZ involves multichannel intracranial electroencephalography (iEEG) recordings,[3] particularly stereoelectroencephalography (SEEG).
