诱发电位测定在神经系统疾病中巳普遍庆用。近十余年来,国内外对脑血管疾病的诱发电位测定也进行了研究: 一、体感诱发电位(SEP):系指皮肤成末梢神经刺激,在刺激的对侧头皮上所记录到的大脑皮质电活动,其检查方法,目前系采用脉冲电流在上肢刺激正中神经、尺神经,在下肢刺激腓总神经等进行诱发、刺激电极置于腕部、肘部 Evoked potentials have been widely used in neurological diseases. Nearly ten years, domestic and international research on the evoked potential of cerebrovascular disease has also been studied: First, somatosensory evoked potential (SEP): refers to the skin into the peripheral nerve stimulation, the contralateral scalp recorded on the stimulation of the cerebral cortex Electric activity, the inspection method, the current Department of pulse current stimulation in the upper extremity median nerve, ulnar nerve, in the lower extremity to stimulate the common peroneal nerve induction, the stimulation electrode placed in the wrist, elbow
