NCT ID NCT04735458

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study records brain activity during deep brain stimulation (DBS) surgery in 140 people with Parkinson's disease or essential tremor. Researchers aim to understand brain networks linked to non-motor symptoms like depression, attention problems, and slow thinking. Participants perform simple computer tasks during surgery while electrodes on the brain surface measure activity.
