Deep Brain Stimulation
Functional Magnetic Resonance Imaging (fMRI) will be performed to determine the areas of BOLD signal modulation with DBS.
Procedure: Functional Magnetic Resonance Imaging (fMRI)
During the deep brain stimulation (DBS) surgery of the subthalamic nucleus within the thalamocortical basal ganglion, an additional lead extendor will be connected to the DBS electrode to allow externalization of the lead. Following confirmation of electrode location with MRI, a series of fMRI scans will be run. Total scanning time will be limited to 35 minutes.
- Mean Score on Unified Parkinson's Disease Rating Scale (UPDRS) [ Time Frame: 6 months after Deep Brain Stimulation ]The UPDRS is a rating scale used to follow the longitudinal course of Parkinson's disease. The version of the scale used in this study has a total of 14 items; each of these item has a scale of 0-4, with 0 being no impairment, and 4 being severe impairment. All of the parts are combined to give a numeric score: 0 indicating no sign of disease, and 56, the highest score indicating severely incapacitated.
