Comments on: Two Brains for the Price of One? http://www.spring.org.uk/2008/03/two-brains-for-price-of-one.php Understand your mind with the science of psychology - Mon, 04 May 2009 10:30:58 +0000 hourly 1 http://wordpress.org/?v=3.3.1 By: Mark http://www.spring.org.uk/2008/03/two-brains-for-price-of-one.php/comment-page-1#comment-21659 Mark Tue, 24 Jun 2008 12:04:00 +0000 http://spring.org.uk/2008/03/two-brains-for-the-price-of-one.php#comment-21659 Noadi: The thing with sight is that it doesn't work like arms/legs. Your right eye isn't just connected to the left side of your brain; it's connected to <b>both</b> sides. What actually happens is that each half of your visual field connects to the opposite hemisphere. So basically the image formed by light hitting each retina is split between the two hemispheres.<br /><br />Which means that right/left eye dominance is almost certainly <i>not</i> due to left/right brain dominance, though not just because the right/left brain dichotomy isn't as clear cut as some believe.

Funny on so many levels, especially when they continue to insist that even after I explain why it's a myth and that even were it true the fact that I'm legally blind in my left eye would force my right to be dominant anyway.

Maybe the author of the article can comment on what seems to me her adherence to the <i>myth</i>.

If I am remembering that correctly it would make language one of the very few things that is not lateralized.
