In the surgery management of lesions in areas of the eloquent cortices the preservation of brain functions is required. Intraoperative electrophysiological methods are necessary to preserve the integrity of the functional network, such as motor or language areas. Cortico-cortical evoked potentials(CCEPs)have recently developed as a new intraoperative monitoring method because of advantages of a recording time of approximately 1-2 min, no requirement of patient cooperation, and high reproducibility and reliability of the data. The recent intraoperative CCEP studies have shown that CCEP can map the eloquent areas and white matter pathway, such as the dorsal language pathway, frontal aslant tract, supplementary motor area, and optic radiation. To establish intraoperative electrophysiological monitoring even under general anesthesia, further studies are required.
在对明确的皮质区域病变进行手术管理时，需要保留脑功能。术中电生理方法对于保留功能网络（如运动或语言区域）的完整性是必要的。皮质-皮质诱发电位（CCEPs）最近作为一种新的术中监测方法得到了发展，因为它具有记录时间约为1 - 2分钟、无需患者配合以及数据具有高重复性和可靠性等优点。最近的术中CCEP研究表明，CCEP可以描绘出明确的区域和白质通路，如背侧语言通路、额斜束、辅助运动区和视辐射。为了即使在全身麻醉下也能建立术中电生理监测，还需要进一步的研究。
