Official title
Sensory Gating Measured With Microelectrode Recording During Deep Brain Stimulation Surgery
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Deep brain stimulation (DBS) is an FDA approved, and widely used method for treating the motor symptoms of Parkinson's disease (PD), Essential Tremor (ET), Dystonia and Obsessive Compulsive disorder (OCD). Over 100,000 patients worldwide have now been implanted with DBS devices. Current approved methods to locate the DBS target regions in the brain use a combination of stereotactic imaging techniques and measurements of the electrical activity of brain cells. As part of the standard clinical technique, electrical data are collected from individual nerve cells. The target brain region emits unique electrical signals. At certain brain locations, during DBS surgery, additional electrical data that are generated in response to sound will be collected. Regions of the brain that have a decreased response to repeated sound (auditory gating) may be important DBS targets for improving thinking. The aims are (i) during DBS surgery, in addition to EEG, use microelectrodes in the brain to find brain regions, along the normal path to the DBS target, where auditory gating occurs and then (ii) determine if stimulation of the identified region(s) alters auditory gating measured by EEG. Also an additional aim (iii) is to measure electrical activity at the scalp with EEG to characterize auditory gating in patients before and after DBS surgery and also a healthy control population.
