摘要。通过将双极电极插入4名有意识的受试者的硬膜外间隙，记录了运动皮层单相和双相磁刺激所引起的下行脊髓齐射。结果表明，双相脉冲的两个相位都能激活下行运动输出。下降活动的补充模式取决于刺激的强度和每次截击相对于电流流向的相对阈值。
Abstract. The descending spinal volleys evoked by monophasic and biphasic magnetic stimulation of the motor cortex were recorded from a bipolar electrode inserted into the cervical epidural space of four conscious human subjects. The results suggest that both phases of the biphasic pulse are capable of activating descending motor output. The pattern of recruitment of descending activity depends on the intensity of the stimulus and the relative threshold of each volley to each direction of current flow.
