5 Dr. Brenda Milner Patient H.M.

6 Amnesia Retrograde Amnesia impairment of memory for events before the injury Anterograde Amnesia impairment of memory for events after injury; that is, an impairment in learning

15 Patient H.M. “Right now I'm wondering, Have I done or said anything amiss? You see, at this moment everything looks unclear to me, but what happened just before? That's what worries me. It's like waking from a dream; I just don't remember.” “Every day is alone in itself, whatever enjoyment I've had, and whatever sorrow I've had.” -- H.M.

16 Working/Short-term Memory –Can carry on a normal conversation –Normal memory span Intelligence and Language Normal –Note that some of these rely on spared retrograde memory (vocabulary, math rules, etc)

17 Skill Learning –“motor, perceptual, or cognitive operations or procedures that are typically acquired through an incremental and slow process of repetition. –Mirror reading –Rotary Pursuit –Artificial Grammar Learning –Perceptual Classification –Tower of Hanoi (not reliable!)

18 Memory Systems in the Brain

21 Medial temporal lobe amnesia Inability to form new explicit memories (anterograde amnesia) Good IQ, good implicit learning Loss of memories from before injury (retrograde amnesia)

22

23 Medial temporal (contains hippocampus) lesions and DNMS performance (working memory)

24

25 Medial Temporal Lobe Memory System Visual Cortex Ventral Stream Inferotemporal Cortex Perirhinal cortex Parahippocampal cortex Entorhinal cortex hippocampus
