[ethos]

Mmm... as far as I know, the whole 'eye' portion of this article is based on a false assumption. I took a class in Neuroanatomy back in highschool, and IIRC the eye is not split with the left hemisphere controlling the right eye and right hemisphere controlling the left eye, but the left hemisphere controlling the _right field of vision_ and the right hemisphere controlling the _left field of vision_. This is why the optical nerve is shaped like this: |X| - with one half of the field of vision going directly to the adjacent lobe and the other half crossing over to the other.

Could be wrong, though.
