Cerebellar TMS evokes a long latency motor response in the hand during a visually guided manual tracking task.

Previous studies showed that transcranial magnetic stimulation (TMS) to the cerebellum evokes a long latency motor response in the soleus muscle during a postural task. The cerebellum is activated not only during postural tasks but also during motor tasks for which eye-hand coordination is required. The purpose of this study was to investigate whether TMS over the cerebellum evokes long latency motor responses in the hand during a visually guided manual tracking task.
