Intraoperative Microelectrode Recordings Using MAVEN Compared to Standard Recording Apparatuses
What this study is about
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.

Interventions
DEVICE
Multifunctional Apparatus for Voltammetry, Electrophysiology, and Neuromodulation (MAVEN)
During deep brain stimulation (DBS) surgery, the MAVEN device will be used in parallel with the currently used Alpha Omega Device to compare the quality of electrophysiologic readings.
Primary outcome measures
Agreement between MAVEN device and Alpha Omega device
Time frame: Baseline
Total number of times the MAVEN device is in agreement with the standard of care Alpha Omega device.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
