cool, sounds like an interesting book! I recently attended a class in which we did a "brain test" so to speak. I was extremely right brained. He actually used the info to help me in class, I believe...
The biggest clue was a test question: I had to define corpus colosum. well, I couldn't for the life of me come up with the words to define it.. I knew what it was.. so I drew the left and right hemispheres of the brain, connected them together with 2 lines and drew an arrow to the correct part of the brain.
then commented "it;s this"
I couldnt believe it when he counted it correct!
