Thalamotomy

Thalamotomy (thalamic ablation) is a procedure that destroys a small portion of the thalamus. The thalamus is a tiny area deep within the brain. It sends and receives sensory and motor (movement) information.

The procedure may help some people who have severe muscle tremors related to Parkinson's disease, essential tremor, or certain other health problems. Thalamotomy can prevent abnormal brain activity from reaching the muscles and causing tremors.
