b. globus pallidus

http://emedicine.medscape.com/articl...view#aw2aab6b3


surgery for movement disorders involved predominantly destructive lesioning of abnormally hyperactive deep brain nuclei; however, the observation that high-frequency electrostimulation in the ventral lateral nucleus (VL) of the thalamus eliminates tremors in patients undergoing thalamotomy led to investigation of long-term DBS as a reversible alternative to lesioning procedures.
