Subthalamic nucleus (STN) and globus pallidum internus (GPi) are two main DBS targets. The sweet spot that leads to optimal control of symptoms is located in dorsolateral STN and posteroventral GPi. Bradykinesia, rigidity, and tremor symptoms listed in blue occur to similar extents with DBS targeted to both STN and GPi. Target-specific clinical benefits are listed in orange.
