Intraoperative neuromonitoring (IONM) complements modern presurgical investigations by providing information about the epileptic focus as well as real-time identification of critical functional tissue and assessment of ongoing neural integrity during resective epilepsy surgery. This chapter summarizes current IONM methods for mapping the epileptic focus and for mapping and monitoring functionally important structures with direct brain stimulation and evoked potentials. These techniques include electrocorticography, computerized high-frequency oscillation mapping, single-pulse electric stimulation, cortical and subcortical motor evoked potentials, somatosensory evoked potentials, visual evoked potentials, and cortico-cortical evoked potentials. They may help to maximize epileptic tissue resection while avoiding permanent postoperative neurologic deficits.
术中神经监测（IONM）通过提供有关癫痫灶的信息以及在切除性癫痫手术过程中实时识别关键功能组织和评估神经完整性，补充了现代术前研究。本章总结了当前用于映射癫痫灶以及使用直接脑刺激和诱发电位映射和监测功能重要结构的 IONM 方法。这些技术包括皮质电图、计算机高频振荡映射、单脉冲电刺激、皮质和皮质下运动诱发电位、体感诱发电位、视觉诱发电位和皮质-皮质诱发电位。它们有助于最大限度地切除致痫组织，同时避免永久性术后神经功能缺陷。
