The motor-evoked potential can be reliably recorded in anesthetized dogs by use of percutaneous placement of active recording electrodes near the dorsal lamina of the vertebral column. Two types of responses were observed in this study; short (less than 5.5 ms at T9-10)- and long (greater than 5.8 ms at T9-10)-latency waves. Short-latency waves are larger in amplitude and appear with higher stimulus intensities than do long-latency waves. Short-latency waves are conducted at greater than 80 m/s and may not reflect pyramidal tract activation. The safety of using higher intensity stimuli to generate short-latency waves has not been determined.
通过将有源记录电极经皮放置在脊柱背侧椎板附近，可在麻醉犬中可靠地记录运动诱发电位。本研究观察到两种类型的反应；短潜伏期波（T9 - 10节段小于5.5毫秒）和长潜伏期波（T9 - 10节段大于5.8毫秒）。短潜伏期波的振幅更大，且比长潜伏期波在更高的刺激强度下出现。短潜伏期波的传导速度大于80米/秒，可能不反映锥体束激活。使用更高强度刺激来产生短潜伏期波的安全性尚未确定。
