Sept 10, 2009 — In slapstick comedy, the fall guy gets the pie in the face when the clown in front of him ducks. It’s funny because most of us instinctively duck when we see something coming. But two recent experimental studies are revealing new automated capabilities built into the eye and brain that are quicker and more automatic than our reflexes or the brain’s visual center.
A team from the Canadian Institutes of Health, publishing in PNAS,[1] ran experiments on a subject that had damage to the visual cortex. They were surprised to learn that the subject could still avoid obstacles in the way during hand-reach experiments. Another experiment showed that the obstacle avoidance was nullified when a 2-second delay was introduced, providing “compelling evidence that these mechanisms can operate in ‘real-time’ without direct input from primary visual cortex (V1),” they said. What does this mean? The subject “was able to code the position of the obstacles despite being unaware of their presence.”

Ping!
And here I always thought that MY eyes see things at exactly the same time I see them.
“This ability may have evolved to speed escape from predators.”
Sure enough!
Who am I to believe? Me or my lying eyes?
But I haven't seen it yet.
In fact, I'm nowhere near the Sears Tower.
That really is amazing.
“This ability may have evolved to speed escape from predators.”
But not likely.
It works!
It REALLY WORKS!
My eyes saw it too, and I’m in Virginia!

Duh. Your eyes have to see something before your brain processes it and then it takes time for your muscles to move away from danger. More wasted $$$$.
Racist.
Autonomic exceeds the cognizant. That’s not a new observation. It doesn’t take much higher thought to have developed reflexive actions. Invertebrates are just as good at avoidance.

Keep in mind that the eye is a physical extension of the brain, and that therefore, in a way, even the eyeball is brain tissue. It could be that there is some sort of low-level processing going on at the retina or optic nerve that bypasses the higher, interpretive centers of the brain for some stimuli.
Surely I get bonus points for actually reading the article.
And it was sausage and onion, right?
I wasn't completely sure about that part. I know I saw the sausage, but wasn't positive about the onions.
I do know that it was the 67th floor, because I had time to count.
And I'm thousands of miles from there. It works!

Your eyes don’t “see” anything until the image is recognized and processed. As it turns out, scientists are discovering that that this capablity exists both in the brain, and for quicker response times, in the eye itself. I would imagine this discovery has profound implications with respect to ophthalmology, etc.
I’m hot for you, baby.
