Research “Distinct roles of the human subthalamic nucleus and dorsal pallidum in Parkinson’s disease impulsivity,” performed by University of Florida neuroscientist, Robert Eisinger and Aysegul Gunduz has been published in Biological Psychiatry. The study shows that brain activity associated with reward processing takes place in two parts of the basal ganglia that are stimulated during deep brain stimulation for patients with Parkinson’s disease, a notable finding in the quest to prevent unwanted side effects of DBS such as impulsivity.
