The intracranial electroencephalogram (iEEG) is essential in decision making for epilepsy surgery. Although localization of epileptogenic brain regions by means of iEEG has been the gold standard for surgical decision-making for more than 70 years, established guidelines for what constitutes genuine iEEG epileptic activity and what is normal brain activity are not available. This review provides a summary of the current state of knowledge and understanding on normal iEEG entities and variants, the effects of sleep on regional and lobar iEEG, iEEG patterns of interictal and ictal epileptic activity and their relation to well-described epileptogenic pathologies and surgical outcome.
颅内脑电图（iEEG）在癫痫手术的决策中至关重要。尽管通过 iEEG 定位致痫性脑区已经成为手术决策的金标准超过 70 年，但目前还没有确定什么是真正的 iEEG 癫痫活动，什么是正常的脑活动的指南。本文综述了目前对正常 iEEG 实体和变异、睡眠对区域性和区域性 iEEG 的影响、iEEG 间发性和癫痫性活动的模式及其与描述良好的致痫性病理学和手术结果的关系的认识。
