Using your "righty" friend

I am currently reading Betty Edwards' Drawing with the right side of the brain and it is being a quite interesting book with fascinating theories and exercises. I reached the book to improve my drawing ability, which I would say, it has been since I was a child a disability.
From the first page you find quite interesting and solidly based theories about the brain, it is composition (some had been treated in this blog between right and left parts of the brain) and how every part works and how to stimulate every part.
One thought quite interesting is the existing stuck in the brain functionality study (in comparison with other subjects) mostly due to the fact that the brain is the only part of the universe which is observing and investigating itself.
Another quite interesting topic is how to get into the right part operation and the "synthoms" you get by being working into that part (time absense, lower cardiac rhythm,...).
