Movement Disorders and Neuromodulation

Edward A. Shipton
2012 Neurology Research International  
Deep brain stimulation (DBS) is used to treat advanced Parkinson's disease, essential tremor, and dystonia.  ...  High-frequency DBS leads to a kind of functional deafferentation of the stimulated structure and to the modulation of cortical activity. This has a profound effect on the efficiency of movement.  ...  Stereotaxis is a minimally invasive surgical procedure that makes use of a three-dimensional coordinate system to accurately locate a target in a deep-seated area of the brain.  ...
