诱发电位测定运用刺激方法,在中枢神经系统引出的电位称作诱发电位。在感觉系统,包括感觉器、感觉神经和感觉通道上施加刺激,由脊髓和脑部引出的电位称作感觉诱发电位。刺激脊髓和脑的运动中枢或传出通道,记录肢体运动的电位称作运动诱发电位。脊髓作为运动和感觉的通道,损伤后可造成上述两类电位的变化,根据记录部位不同,又各有其称谓。

Evoked potential measurement using stimulation methods, the potential of the central nervous system leads to the evoked potential. In the sensory system, including sensory, sensory and sensory channels to stimulate the spinal cord and the brain leads to the potential called sensory evoked potential. Stimulation of the spinal cord and brain motor center or the outgoing channel, recording the limb movement potential called motor evoked potentials. Spinal cord as a channel of movement and feeling, after injury can cause the above two types of potential changes, according to different parts of the record, but also have their names.
