Design outcomes

Primary

MeasureTime frame
1) Urge correlated connectivity between cortical areas (SMA, PFC, ACC) and the DBS target in the theta (4-8 Hz) and beta (15-30 Hz) frequency bands.

Secondary

MeasureTime frame
2) Movement planning and movement execution-correlated connectivity between cortical areas (SMA, PFC) and DBS target in the delta (1-4 Hz) and theta (4-8 Hz) frequency band. 3) Connectivity between cortical areas (SMA, PFC, ACC) and DBS target in the delta (1-4 Hz), theta (4-8 Hz), alpha (8-12 Hz), and beta (15-30 Hz) frequency bands at rest. 4) Modulation of connectivity profiles in 1., 2., & 3. by THS.
