FURTHER COMMENT: Perhaps you do not quite grasp what I am saying about
the right hemisphere's role in attention. I don't know if Ramachandran
really puts it in such mentalistic/cognitive terms; but even if he
does, please note the distinction in any case between ability to SEE
things in the right visual field and NOTICING things there. A subtle
but important distinction. For a less mentalistic/cognitive way of
loooking at it, consider Ken Heilman's several papers on the right
hemisphere's role in activation/attention for the entire brain.

AND YET FURTHER COMMENT: May I take that to mean "one word, to the
wise, is sufficient"? You'll be more circumspect in your assertions in
