Experimental: Deep Brain Stimulation subjects |
Diagnostic Test: Functional MRI
A special type of MRI measuring the metabolic changes that occur within the brain. It may be used to examine the brain's anatomy and determine which parts of the brain are handling critical functions. It helps identify important language and movement control areas in the brain. |
