He couldn’t even remember certain memories from 11 years prior to the surgery. This is called Anterograde Amnesia; loss of the ability to create new memories after the event that caused the amnesia, leading to a partial or complete inability to recall the recent past, while long-term memories from before the event remain intact. He still retained the ability to create new motor memories. With repetition, Henry was able to learn new things even if he didn’t remember he learned it. Dr. Brenda Milner, a psychologist from McGill University in Montreal, assisted Dr. Scoville in studying Henry Molaison. She asked Henry to complete a star outline by drawing in the last lines multiple times a day, and even though he didn’t remember doing the test multiple times before, he showed improvement in his lines every time he completed this test. This showed that he was able to learn new things through repetition even if he couldn’t remember learning
