诱发电位(Evoked Potential,EP)系指人工的或自然的刺激所引起的中枢神经系统的电位变化,是研究中枢神经系统机能的一种重要方法。EP开始於1913年Pravdish-Neminsky的电生理学实验:电刺激狗的坐骨神经后,可在其皮层脑电图上出现明显的电波偏移现象。从此以后,证明是一种非常广泛的活动传导到皮层而反映出的记录,因而EP的记录技术便成为追踪研究外周冲动到达皮层通路的一种技术或方法。脊髓是头部以下运动和感觉的总通道,如发生损伤即可造成皮质和脊髓诱发电位的变化。皮质诱发电位(Corticol Evoked Potentials,CEP)变化正常CEP:刺激周围神经(如胫神经、
Evoked Potential (EP) refers to the central nervous system caused by artificial or natural stimulation of the potential changes, is an important method to study the function of the central nervous system. EP began in 1913 Pravdish-Neminsky electrophysiological experiments: electrical stimulation of the sciatic nerve in dogs, in its cortical EEG obvious wave shift phenomenon. Since then, it has been proven that a very broad range of activities are transmitted to the cortex to reflect the recorded records. Therefore, EP recording technology has become a technique or method for tracking the peripheral impulse to reach the cortical pathways. Spinal cord is the head of the general movement and sensory path, such as injury can cause cortical and spinal cord evoked potential changes. Corticol Evoked Potentials (CEP) changes normally CEP: stimulation of peripheral nerves (such as the tibial nerve,
