H.M. (Henry Gustav. Molaison, 1926–2008). “(…) After operation this young man could no longer recognize the hospital staff nor find his way to the bathroom, and he seemed to recall nothing of the day-to-day events of his hospital life. (…) he did not remember the death of a favourite uncle three years previously (…). The family moved from their old house to a new one a few blocks away on the same street; he still has not learned the new address, though remembering the old one perfectly, nor can he be trusted to find his way home alone. (…) This patient has even eaten luncheon in front of one of us (…), a mere half-hour later (…) he could not remember having eaten luncheon at all. Yet to a casual observer this man seems like a relatively normal individual, since his understanding and reasoning are undiminished.”. Steven . Pelley. , Peter M. Chen, Thomas F. . Wenisch.
