Study Details

Brief summary:

The purpose of this study is to better understand the roles the cerebellum, basal ganglia, and thalamus play in motor learning. Patients undergoing High Intensity Focused Ultrasound (HIFU) treatment will be receiving an ablation procedure to their thalamus as a part of their medical procedure. Participation in this study will include completing a behavioral task before and after the procedure to see how motor learning task performance differs with and without the thalamus. Similarly, patients undergoing Deep Brain Stimulation (DBS) treatment will have an electrode implanted in their thalamus as a part of their medical procedures. Participation in this study will include completing the motor learning task performance "on" and "off" thalamic electrical stimulation.

Interventions and Outcome Measures

Arms

experimental: High Intensity Focused Ultrasound

Patients receiving high intensity focused ultrasound as a treatment will be asked to complete the behavioral task pre and post their treatment.

experimental: Deep Brain Stimulation

Patients receiving deep brain stimulation as a treatment will be asked to complete the behavioral task while their DBS electrode is "on" and "off".

Interventions

Behavioral Assessment

Patients will be asked to complete the behavioral assessment before and after their HIFU treatment or "on" and "off" their DBS treatment.

Primary outcome measure

  • Performance Error on Visuomotor Task [ Time Frame: baseline, a week after HIFU treatment, several weeks after DBS implantation ]
