A Study of a New Recording Electrode to Record Brain Activity During Surgery


About this study

This research study will investigate a new recording electrode that will record brain activity during surgery. This electrode is being tested for efficacy, and may eventually replace the current electrodes used for this purpose. The goal is to record brain activity in a region of the brain that is already being removed to treat epilepsy.
