A great many patients are represented in this book, usually through a question they asked or a concern they expressed. Some were the patients undergoing operations such as Neil’s, who contributed much knowledge through their cooperation.

That is because “Neil” is not merely a pseudonym but a composite (and should not be cited in the manner of a case report) of several temporal lobe epileptics who cannot be further identified, for all the usual reasons of patient confidentiality. He is a
