Intraoperative electrical stimulation of the motor cortex is a sensitive method for intraoperative mapping and monitoring of this region. Two different stimulation techniques have been established, the bipolar and monopolar techniques. Controversy exists regarding the most suitable method. Both methods have advantages and disadvantages and different electrophysiological backgrounds. The present study is a review of the electrophysiological basis of direct cortical electrical stimulation of the motor cortex. Both methods are discussed and their field of application is presented.
术中对运动皮层进行电刺激是对该区域进行术中图谱绘制和监测的一种敏感方法。已经建立了两种不同的刺激技术，即双极技术和单极技术。关于最合适的方法存在争议。这两种方法都有优缺点，且具有不同的电生理背景。本研究是对运动皮层直接皮层电刺激的电生理基础的综述。对这两种方法都进行了讨论，并介绍了它们的应用领域。
