Abstract
Surgery for resection of cerebral tumors or epileptic foci carries risks of damage to cortical areas involved in sensory, motor, language, and memory function. Even with modern anatomic and functional imaging techniques, preoperative studies are not sufficient if the surgeon wishes to obtain maximal resection of abnormal tissue while preserving neural function. Thus, intraoperative mapping techniques have been utilized for nearly 80 years to provide detailed delineation of functional areas during surgery. This chapter reviews the current state-of-the-art techniques and also briefly considers new techniques now being developed. While language and memory mapping during awake craniotomies will be discussed, the primary emphasis will be on techniques for mapping sensory and motor cortical regions during craniotomies performed under general anesthesia.
