A man known only as H.M. is the reason we know as much as we do about the brain.H.M., who died earlier this week at the age of 82, lost his memory after he underwent experimental brain surgery in the 1950s. For decades he worked with researchers who learned from his case how memory functions. New York Times human behavior and psychology reporter Benedict Carey explains our debt to him.
