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.
本文描述了一种用于硬膜外记录脑电活动的新型电极设计。硬膜外栓状电极是由硅橡胶弹性体与不锈钢或铂盘组成的可植入蘑菇形复合材料。这些电极对于一些存在颅骨缺损或头皮记录时有严重肌肉伪迹的患者进行术前癫痫灶定位很有用。它们还用于大面积皮层的探测，以确定癫痫发作是局灶性起源、从一个半球广泛起源还是双侧起源。硬膜外栓状电极相对于螺钉和其他类型硬膜外电极的优点包括感染或出血风险低以及患者舒适度提高。
