Official study title

Intraoperative Microelectrode Recordings Using MAVEN Compared to Standard Recording Apparatuses

Original description

The purpose of this research is to determine if the electrophysiologic data collected from standard-of-care microelectrode recordings during human deep brain stimulation (DBS) surgery will be the same using the MAVEN device compared with the standard Alpha Omega device with either a tungsten standard-of-care microelectrode (for microelectrode recordings), or a carbon-fiber microelectrode (for neurotransmitter recordings). The number of microelectrodes used for both the tungsten and the carbon-fiber version will be the same as the standard-of-care.

Conditions reported: Essential Tremor; Parkinson's Disease; Dystonia

Study type: Observational
Interventions: Multifunctional Apparatus for Voltammetry, Electrophysiology, and Neuromodulation (MAVEN)
