It's been a while since I've taken the classes, but in some of my psyc
we discussed the case study of a patient who had epilepsy so severe that
resorted to surgery on his hippocampus. I managed to pull up some info
from google:


The significance of the hippocampus is driven home by a famous patient
named H.M. As part of an epilepsy surgery, doctors removed most of his
medial temporal lobes. Since that surgery, in 1953, he has formed no new
memories. He can remember his childhood and everything before the
surgery, and he still has working memory and the ability to form
procedural memories. You can have a normal, lucid conversation with him,
but if you leave the room for a moment, when you return he will not
remember you or the conversation. He has completely lost the ability to
lay down declarative memory.

We discussed other patients in the class and studies done on them and how
learning had changed. I vaguely remember that they would do exercises
where they
wouldn't retain the memory of the exercise, but on latter trials their
curves were improved.

A condition that mimics this is Korsakoff's Syndrome which arises from
alcoholism. It produces lesions in that region of the brain. One of
Oliver Sacks'
books has a case study on it.

If you want to read about memory, but the flip side, Luria has a case
study about
a man with eidetic memory _The Mind of a Mnemonist_. Luria has some
case studies.
