No, the human brain isn't capable of visualizing four (or more) dimensions.

They would make great surgeons - they could operate on us without even cutting us open.

We live in 4 dimensions every day so its easy(3 spacial, 1 time). I think you mean 4 spacial dimensions. :o

Many scientists think we live in up to 11 or 12 dimensions everyday (depending on the partiular string theory).

Doc Smith used this very idea in Skylark of Valeron.

Old-time space opera. Great stuff.

I agree there wedge. The most popular are ten spacial dimension models and i think some believe 12 spacial dimensions. These 'extra' dimensions are believed to be curled up into a "Calabi-Yau space". All pretty mind blowing stuff. Ive been reading Greenes book(actually its my second attempt :o ), the elegant universe, its real good stuff.

Hm, is there another book of about that depth on String theory? I've started Greene's book, but it annoyed me because it was a little too slow for me, but maybe that was just Greene's style.
Any suggestions that don't require a PhD in physics?

Hyperspace by Michio Kaku is an excellent read, and mostly written in layman's (laywoman's) language.

Yeah Greene's style was a little annoying. It went from childish explanations to some really confusing examples to quite technical aspects all in the same chapters. The thing is though no-one really understands string theory and it is a difficult concept so i do sympathise with Greene.
Try to stick with it, ive nearly read it twice over as its that good if you are into this type of thing.

I am gonna check out, Hyperspace by Michio Kaku.
