NCT03079037

Brief Summary

This study will test the hypothesis that deep brain stimulation (DBS) targeting specific changes in oscillatory activity at the site of stimulation will prove superior to continuous isochronal DBS thus providing the rationale for development and optimization of closed loop paradigms and determine whether the optimal closed-loop biomarker varies across subcortical targets, is task dependent, or serves to re-establish a default network that removes an underlying disruptive physiological state leading to greater improvement in motor signs and task performance.
