Abstract The resection of the epileptogenic area of brain is very important and useful for the treatment of uncontrolled epilepsy, especially for the patients with stereotyped partial seizures. The critical point for successful epilepsy surgery is the precise identification of epileptogenic zone. Actually, we cannot precisely localize the epileptogenic zone in about 25 \% of patient with refractory seizures based on the noninvasive examination; thus for these patients, we mainly use the intracranial EEG to localize the epileptogenic zone which could be useful in 10-15 \% of surgical candidates. The intracranial electrodes which are most used currently are depth electrodes, subdural strip electrodes, and subdural grid electrodes. The subject of this paper is to discuss and compare the indications, construction, insertion, interpretation, limitations, risks and accuracy of each of these methods.
