We investigated whether long latency motor response induced by transcranial magnetic stimulation over the cerebellum (C-TMS) preferentially appears during a continuous visually guided manual tracking task, and whether it originates in a concomitantly evoked neck twitch. C-TMS or magnetic stimulation over the neck (N-MS) was delivered during one of four tasks: a continuous or discrete visually guided manual tracking task, or phasic or tonic contraction of the first dorsal interosseous muscle. The probability of long latency fluctuation of index finger movement induced by C-TMS was not significantly different from that induced by N-MS, but the probability of long latency fluctuation induced by C-TMS and that induced by N-MS was significantly higher than that induced by sham TMS during all the tasks. The probability of long latency electromyographic response in the first dorsal interosseous muscle induced by C-TMS was significantly higher than that induced by N-MS and that induced by sham TMS during the continuous visually guided manual tracking task. Such significant differences were not present during the other tasks. Long latency electromyographic response induced by C-TMS preferentially appears during the continuous visually guided manual tracking task and is not explained by a concomitantly evoked neck twitch.
我们研究了经颅磁刺激小脑（C-TMS）诱发的长潜伏期运动反应是否优先出现在连续视觉引导手动跟踪任务期间，以及它是否源自同时诱发的颈部抽搐。C-TMS 或颈部磁刺激（N-MS）在四个任务之一中给予：连续或离散的视觉引导手动跟踪任务，或第一背侧骨间肌的相位或紧张收缩。C-TMS 诱导的食指运动长潜伏期波动的概率与 N-MS 诱导的长潜伏期波动的概率无显著差异，但 C-TMS 诱导的长潜伏期波动的概率与 N-MS 诱导的长潜伏期波动的概率以及假 TMS 诱导的长潜伏期波动的概率均高于所有任务期间。C-TMS 诱导的第一背侧骨间肌长潜伏期肌电图反应的概率在连续视觉引导手动跟踪任务期间显著高于 N-MS 和假 TMS 诱导的长潜伏期肌电图反应的概率。在其他任务中没有出现这种显著差异。C-TMS 诱导的长潜伏期肌电图反应优先出现在连续视觉引导手动跟踪任务期间，不能用同时诱发的颈部抽搐来解释。
