NCT01705301

Brief Summary

In this study, the investigators will monitor extracellular neurotransmitter levels using a probe that is able to perform real time electrochemical detection during deep brain stimulation surgery. The overall question this study is designed to answer is: Are there neurotransmitters released during deep brain stimulation?

Outcome Measures

Primary Outcomes (1)

  • adenosine release in brain as measured by WINCS (Wireless Instantaneous Neurochemical Concentration Sensing System)recording device

    Pre, during, post DBS (deep brain stimulation)

    30 minutes

Secondary Outcomes (1)

  • dopamine release in brain as measured by WINCS (Wireless Instantaneous Neurochemical Concentration Sensing System)recording device

    30 minutes

Study Arms (1)

Deep Brain Stimulation

Patient's undergoing the clinical procedure of Deep Brain Stimulation will have the experimental protocol that involves, after implantation of the DBS electrodes, a single electrochemical recording electrode, from the WINCS system, implanted along the same trajectory path as the electrophysiology and the DBS electrode

Device: WINCS
