Depth Electrode Detection of Cortical Spreading Depolarization After Traumatic Brain Injury

During the standard of care External Ventricular Drain (EVD) placement, a depth electrode with minimal modification to the standard surgical procedure will be placed. This will allow electrocorticogram (ECoG) recordings. An ECoG will be reviewed by a study Neurosurgeon to understand the association between cortical spreading depression and pathological findings on imaging. The recordings help create a novel algorithm in order to detect CSD's. This may ultimately provide significant benefit to society through the diagnosis and treatment of secondary injury associated with traumatic brain injury.
