Oh, how wrong you are.
My vision is 20/60(L) and 20/200 (R)!. I'll see farther than you any day ;-)

The eye can definitely see more than 60hz, or the 60hz 'flicker' effect would exist. You wouldn't be able to tell it was flickering if it was refreshing at the limit of what your eye can see.
Now, your eye may not be able to see 200 discrete images per second, but it definitely gets more data from that than from say 100hz. (from tests done by various groups, including the military and microsoft, 200hz still shows an improvement over lower speeds, though I'm not sure if any tests were done on refresh rates beyond that, though the military's tests were on firing ranges and showed that a lag as small as 1/200th of a 2nd can still have a notable effect on a soldier)

Ah, the classic God complex of the neuroscientist. Only the brain/nervous system are challenging! Since I study them, I are teh smartest! :roll: The only reason you think this is true is because you've spent your time studying the neurophysiology instead of the eye itself. I've spent plenty of time studying the eye and a little on the neuro - enough to know that there is sufficient complexity in any one subsystem of either to occupy a dozen lifetimes of a researcher.
You are correct of course. The eye is fantastically complex and wonderfully functional.
BTW i dont have a god complex... but do you know where i can get one?
Interesting i came across this today. I just watched a show on Discovery last night. It detailed part of what your saying. The gist of it was that there are 2 data streams originating in the eye. They are fed to a part of the brain (which they named with an acronym, and i'm not neuroscientist.) From there it was separated into a perception oriented data stream, and an action oriented data stream. The former went to a part of the brain that allowed it to be acted on in a conscious manner, and became part of our perception of the world. The latter went to a different part of the brain that basically allowed the body to act on the eye's information, before the conscious mind could even perceive it.
Fascinating stuff.
In a related vein. I read a book not too long ago. Science fiction but well grounded in hard science. The main idea of the story was having our consciousness downloaded into a computer brain and body as a means to immortality. The heart of the story was a thorough examination of consciousness. There was an idea that the (human) body primarily acts autonomously from our consciousness, something they called our Zombie. It basically knows what to do, and does it with minimal direction from us. We correct it when it's doing something we consciously don't intend to do, but a lot of time it's after our body has already begun to do something we've never consciously decided to do at all.
I realize now why it's so hard to stop snacking on sunflower seeds or the like. Our body has already started grabbing the next handful, and by the time I decide i'm done, that handful is already on its way to my mouth. Easier to stop on the next handful right? Except it's on its way when i make the decision again.

I thought you got one free with every diploma that has the word 'neuro' on it. At least, I know that's true here at WashU.Originally posted by: Xdreamer

you are correct. The unconsious stream is what provides hand eye coordination, the blink reflex, you not getting motion sick when you walk, you being able to focus on objects when you move, your ability to focus on objects, eye dialation, and much more.
it is indeed facinating stuff

You know what they say about neuroscientists, we're all mental.
Nah, I didn't get one... now I feel gipped. :laugh:
No offense intended to the noble eye, but i find the 1400 odd ml of oatmeal like mush in your skull (brain) which recieves, integrates, and responds to many sensory modalities, to be far more complex and interesting than the eye.
But that is just one mans oppinion.
And the opinion of every other neuroscientist I've ever met.
No one is going to argue that the brain is simple. I'm just saying that other things are also complex and worth studying. And that power laws weren't invented by neurologists to describe the response function of sensory perception - they were developed by engineers for rheological purposes. We've just loaned them to you guys.

Why thank you.
BTW I love your sig.Thanks. I can't take credit for the quote though - I saw it on a sign in a bar that one of my brothers used to work in.Originally posted by: Xdreamer
