The Man Who Mistook His Wife For A Hat (Oliver Sachs) is a book
that you might find interesting. Although it is technically clinical
neurology case studies and not neuropsych., I think that it is a great
place to begin. In fact it's where I started my studies in neuropsych.
a few years ago. You can read it in a weekend and it will serve as
inspiration to wade through basic neuroanatomy/physiology texts later
Have fun, Scott
