Abstract

A new electrode design for the extradural recording of electrical brain activity is described. Epidural peg electrodes are implantable mushroom-shaped composites of Silastic elastomer and a stainless steel or platinum disc. These electrodes are useful for the preoperative mapping of seizure foci in some patients who have cranial defects or severe muscle artifacts on scalp recordings. They are also used for canvassing wide areas of cortex to determine whether a seizure is focal in origin, arises diffusely from a hemisphere, or has a bilateral origin. Advantages of epidural peg electrodes over screw and other types of epidural electrodes include low risk of infection or hemorrhage and improved patient comfort.
