How does Deep Brain Stimulation (DBS) of the subthalamic nucleus (STN) work?
Deep Brain Stimulation works by modifying the electrical activity of the sub thalamic nucleus (STN) deep in the brain, which is involved in motor control. The external source of electrical signals are produced by a neurostimulator implanted beneath the skin near the collarbone of the patient and it is delivered to the brain via a thin, insulated coiled wire that is implanted in the STN.The electrical stimulation can be adjusted from outside. In addition, the patient can turn the stimulation completely off, when it is not required, although most patients will require and prefer to leave the neurostimulator on all the time.
