It's going on now and for the next ~50 hours. The brain belongs to H.M., the guy that the movie Memento is 'based on'. When he was alive, he could not create new short-term memories. He's been the subject of study for years until he passed in 2008.

Watching this is a bit weird, it's reminiscent of a deli meat slicer.

This may be picking nits, but HM could not create new long term episodic memories. He could use short term memories and learn new skills, but he couldn't remember times, places, and events.

He could learn declarative knowledge like that, but not very well. http://www.npr.org/templates/story/story.php?storyId=7584970 - Dr. MILNER: How about 1963? Someone was assassinated.

H.M.: He'd been a president.

Dr. MILNER: That's right.

H.M.: And he was assassinated.

Dr. MILNER: What was his name?

H.M.: He had been, like you said, he had been a president.

Dr. MILNER: His initials are JFK.

H.M.: Kennedy.

Dr. MILNER: That's right. What was his first name?

H.M.: John.
