In fact, the retina can be thought of in a way as a tiny bit of the brain that's actually in the eye. The interesting thing is that there's actually processing going on _in the retina_, or more precisely in the neurons behind the retina, before the signals are passed to the brain itself. (The upside-down part comes from the fact that the image projected on our retinas is upside-down. Our visual process compensates for this. One experiment in the 70's or early 80's involved someone wearing a getup that inverted his visual field. After a couple of weeks of stumbling around running into things, it "flipped" and he was seeing things right-side-up again. After he took off the getup, he had another couple of weeks of stumbling before his brain re-learned to compensate and "flipped" it back.) -- Frank Mayhar frank at exit.com http://www.exit.com/ Exit Consulting http://www.gpsclock.com/ http://www.exit.com/blog/frank/
