The Motor Network in Essential Tremor: Mechanisms of Therapy

Deep brain stimulation is a neuromodulatory therapy in which electrodes are implanted in deep brain structures. Electrical pulses are delivered through these electrodes to suppress pathological activity that are causing the symptoms of essential tremor or Parkinson's disease.

Ad-Tech Medical Instrumentation Corp. electrodes are intraoperative monitoring subdural strips will be placed on the surface of the cortex (non-penetrating).

Brain signals will be recorded using the clinical Participants in this group with Parkinson's disease will be undergoing deep brain stimulation implantation surgery as part of the standard of care. In addition, the Ad-Tech Medical Instrumentation Corp. device will be used to test responses with wireless sensors placed on the participant's arms, which can record EMG activity. Brain signals will be recorded using the clinical FHC Guideline 4000+ system and/or Medtronic RC+S devices, which are capable of recording during stimulation.
