What's new with the amnesic patient H.M.?

Nature Reviews Neuroscience volume 3, pages 153–160 (2002)Cite this article

Abstract

H.M. became amnesic in 1953. Since that time, nearly 100 investigators, first at the Montreal Neurological Institute and since 1966 at the Massachusetts Institute of Technology, have participated in studying him. We all understand the rare opportunity we have had to work with him, and we are grateful for his dedication to research. He has taught us a great deal about the cognitive and neural organization of memory. We are in his debt.
