Intracranial Electrode Placement

Sometimes the root cause of epileptic seizures is difficult to find. When routine EEGs using electrodes on the scalp surface cannot locate where a patient’s seizures are originating, neurosurgeons may need to do more invasive monitoring. Intracranial electrode placement is a surgical technique that puts electrodes directly on the surface of the brain, allowing for very precise and effective EEG monitoring.

Intracranial EEG monitoring is used to precisely map epileptic areas of the brain. The neurosurgeons at Barnes-Jewish & Washington University Comprehensive Epilepsy Center can place these electrodes, referred to as intracranial strip electrodes, grid electrodes or depth electrodes.

Not only does this technique allow for very precise mapping of areas causing the onset of seizures, but it also helps physicians identify and map critical areas of the brain, such as those controlling speech and motor control, that will need to be avoided during surgery. 

By identifying which areas of brain need to be removed and those that need to be preserved, neurosurgeons are able to improve seizure outcomes and reduce serious permanent neurologic injuries after surgery.

The neurologists and neurosurgeons at the Comprehensive Epilepsy Center have extensive expertise in evaluating patients and performing intracranial electrode placement, with past experience in hundreds of cases.

Intraoperative MRI (IMRI)

Barnes-Jewish has the most advanced operating room imaging technology in the world at its disposal with the installation of a multi-room iMRI surgical imaging suite, enabling neurosurgeons to perform important MRI tests while surgery is in progress. Find out more in this video.
