  • THE CASE STUDY OF H.M.
    • WHAT HAPPENED TO H.M?
      • >Henry Molaison (H.M) suffered from severe epilepsy.
      • >Surgical procedure was carried out to remove his hippo-campus (learning, emotion and language)
      • >Reduced the epilepsy
      • >However he was left with severe amnesia- anterograde amnesia - He was unable to form new memories while memories before the incident remained intact.
      • >He also suffered from retrograde amnesia- he could not remember events before the operation (11 years)
      • >He could no longer form new episodic memories but his ability for procedural learning remained intact
    • WHAT DOES H.M'S CASE TELL US ABOUT THE NATURE OF MEMORY?
      • >However he was left with severe amnesia- anterograde amnesia - He was unable to form new memories while memories before the incident remained intact.
        • >Supports the idea that we have a long term memory
      • >Not being able to create new LTM.
        • >Supporting the idea that we do have separate STM that is needed to make LTM
      • >He also suffered from retrograde amnesia- he could not remember events before the operation (11 years)
      • >He could no longer form new episodic memories but his ability for procedural learning remained intact
        • >Suggests our LTM has different components, one part deals with episodic memory (events) and procedural memory (motor skills)
