Fahn S, Tolosa E, Marin C. Clinical rating scale for tremor. In: Youmans and Winn Neurological Surgery. 7th ed. Deep Brain Stimulation (DBS) Like a pacemaker for the brain, deep brain stimulation (DBS) controls electrical signals in the brain to help control abnormal movements such as tremors and involuntary muscle contractions. In some cases, surgery can be done under general anesthesia so that you'll be unconscious. Deep brain stimulation (DBS) is a neurosurgical procedure that allows targeted circuit-based neuromodulation. © 2021 American Association of Neurological Surgeons. DBS is a complicated procedure that requires a skilled and knowledgeable surgical team and highly specialized equipment. Once the system is in place, electrical impulses are sent from the neurostimulator up along the extension wire and the active contacts of the lead in the brain. Deep brain stimulation (DBS) uses electrical impulses to stimulate a targeted area in the brain. [CDATA[// >
