Toronto Talk, Oct. 9th: Permanent Present Tense: The Unforgettable Life of the Amnesic Patient, HM

For anyone in the Toronto area, an upcoming talk at the Royal Ontario Museum (ROM) may be of interest. On October 9th, at 6pm, Dr. Suzanne Corkin will be speaking on her recent book, Permanent Present Tense: The Unforgettable Life of the Amnesic Patient, HM. Corkin spent decades studying the patient popularly known as H.M., who was revealed to be Henry Molaison after his death in 2008. (See  AHP’s previous post on the fate of H.M.’s brain here.) Research with H.M., who was unable to form longterm memories following extensive brain surgery for epilepsy, was central to psychological work on how longterm memories are formed.

The event – sponsored by the Faculty of Health, York University, the Rotman Research Institute at Baycrest, and the Department of Psychology, University of Toronto – is free to attend but pre-registration is required. The Permanent Present Tense lecture is described as follows,

Dr. Suzanne Corkin is an esteemed memory expert and Professor Emerita of Neuroscience in the Department of Brain and Cognitive Sciences at MIT (Cambridge, MA). Dr. Corkin is best known for her work with one of the most famous cases in medical history, the amnesic patient Henry Gustave Molaison. In her lecture, Dr. Corkin will speak about their nearly 50-year research partnership, which taught us much of what we know today about memory. Her lecture will be followed by a signing of her recent book, Permanent Present Tense, which documents the incredible story of H.M. and his groundbreaking contributions to the science of memory.

Henry Molaison Dies

Henry Molaison: For decades he has been known by virtually every student of cognitive neuroscience by his initials alone: H. M. The story is familiar to anyone who has studied memory over the past 50 years: In the 1950s, as a young man, he had a life-threatening case of epilepsy. Portions of his brain, including the hippocampus, were surgically removed in an effort to stop the seizures. The operation was effective but, before long, an unexpected and terrible side effect of the operation was discovered. H. M. was no longer able to form new long-term memories. He could remember much of his life from before the surgery. His personality remained essentially intact, but after less than a minute he would forget anything that he had experienced. He could not even remember the doctors, nurses and other people responsible for his care whom he had met dozens of times. Then Brenda Milner of the Montreal Neurological Institute discovered that H. M. could improve at complicated motor tasks such a mirror drawing, even though he would not recall having done the task before. And thus began the modern movement in memory theory to divide this central mental faculty into a set of distinct memory “systems”: implicit and explicit, procedural and declarative, and so forth.
