I would have expected a whole lot more than that. It must be because theres not much required to control them. Just left right, etc...and the rest is just visual input. I still don't get how it can be so little, comparatively. The thumbs take a lot. I would think that it would be the pointer finger that would take the most. If we were to make a computer program to do equiv things that a brain can do and did organ size by processing power required, i would imagine this would be drastically different, especially in the eye area.
