Brief Summary
This study will help us better understand how the brain works in people with Parkinson's disease (PD). PD is a brain disease that gets worse over time, and affects over 10 million people world-wide. A common treatment for PD is Deep Brain Stimulation (DBS). To improve DBS therapy for PD, we need a deeper understanding of how the different parts of the brain work together in PD, and how this relates to movement and thinking problems that people with PD experience. We may be able to use the results of this study to improve DBS treatments in the future.

Outcome Measures
Primary Outcomes (4)
reach-related modulation
reach-related modulation in beta/HFO power in DBS lead LFPs across OFF, DBS, L-dopa, and DBS+L-dopa conditions.
2 days
N-back task trials
directed connectivity between STN and DLPFC compared between the N-back task trials with and without stimulation.
2 days
rigidity and bradykinesia assessments
differences in rigidity and bradykinesia assessments between conditions: off-stimulation vs eiDBS-suppression, off-stimulation vs eiDBS-amplification, eiDBS-suppression vs eiDBS-amplification.
1 day
peak frequency of the ERs + spontaneous LFPs
the correlation between the peak frequency of the ERs in the GPi (or STN) and that of spontaneous LFPs in the GPi (or STN).
1 day
Secondary Outcomes (3)
N-back task trials
2 days
rigidity/bradykinesia measurements and correlations to conditions
1 day
task vs. rest and topographical location
2 days
Study Arms (1)
Parkinson's disease
* Diagnosis of idiopathic PD * Surgery at UMN to implant DBS system with directional lead(s) and multiple independent current control IPG is planned as part of routine clinical care * At least 21 years old * Existing or planned 7T brain imagery
Eligibility Criteria
PD patients
You may qualify if:
- Diagnosis of idiopathic PD
- Surgery at UMN to implant DBS system with directional lead(s) and multiple independent current control IPG is planned as part of routine clinical care
- At least 21 years old
You may not qualify if:
- Other significant neurological disorder
- History of dementia
- Patients with post-operative complications or adverse effects (e.g. ON stimulation dystonias) that affect patient safety or confound the experiment will be excluded from further study
- Pregnant women
- Known radiation exposure within the last year that is determined to be unsafe when compounded with the expected radiation dose from intraoperative fluoroscopy to place ECoG strip
