Fig. 3: Ventral intermediate nucleus of the thalamus (VIM) plays a central role in tremor activity and may be a target of tremor interference.

Acute cognitive stress, deep brain stimulation (DBS), and dopamine could influence VIM and thus regulate tremor. DBS with different frequency present a different effect on tremor activity. Orange arrows indicate excitatory effect, blue arrows indicate inhibitory effect.
