title: Effects of transcranial magnetic stimulation over the cerebellum on triphasic electromyographic pattern.
abstract: The purpose of this study was to investigate the effects of transcranial magnetic stimulation (TMS) over the cerebellum on the triphasic electromyographic (EMG) pattern. Eight healthy subjects extended the left wrist as fast as possible in response to a start cue. TMS was delivered over the cerebellum 50 ms after the start cue. TMS over the cerebellum produced shortening of the latency in the first agonist burst, and an increase in the EMG activity of the antagonist burst. The triphasic EMG pattern may be partially under the control of the cerebellum.
