Five years have elapsed since my initial report on the results of temporal lobectomy for psychomotor epilepsy (Davidson Lecture).1 Bailey and Gibbs *; Green, Duisberg, and McGrath3; Bailey, Green, Amador, and Gibbs,4 and others † have reported their results. Encouraging results have been obtained, and each investigator has cautioned against premature conclusions. I cannot emphasize too strongly that the operations employed in my series are considerably different from those used by other workers. The uncus, the hippocampal gyrus, and the amygdaloid nucleus were also removed during each of the "standard" operations.

This report concerns 36 private patients having uncontrollable psychomotor seizures who have been subjected to temporal lobectomy. The average follow-up period since operation is five years (first operation, Oct. 27, 1946; last, Oct. 21, 1952).

The basis of removing epileptogenic foci associated with pathological lesions has been carefully formulated by Penfield and his co-workers.‡ But as late
