Detail: He lived 1891 to 1976, studied local epilepsy, found epileptic brain-lesion locations and extents [1938], and surgically treated local epilepsy. He electrically stimulated brains to find regions needed for language, but he also elicited images and sensations, which are same dream-like sensations that patients experience when epileptic [Penfield, 1975] [Penfield and Perot, 1963]. Removing tissue did not delete sensation.
