Karyn, dinna fash yersel'. I've been reading a lot about the brain (in actual books, too, not just blogs). If you haven't read Sharon Begley's Change Your Mind, Change Your Brain, I think you'd enjoy it. (As I always say, bad title but great book.) For one thing, she explains how areas of the brain normally used for vision or for hearing are used in blind or deaf people.

Way further down at the cellular level, though just as interesting to me: Eric Kandel's In Search of Memory. You'll learn a hell of a lot about the sea slug Aplysia, but you might enjoy the trip.
