light hits the eye and it`s converted to an electrical signal that travels down the optic nerve to the brain.

 

HOW? and in what way?

 

is the optic nerve millions of little nerves each carrying the data from a pixel each? is it one nerve that carries the data from one pixel at a time but very fast like the scan on a TV screen?

 

how does it work?

Hope thats ok, Gray was excellant at anatomy/pathology.

interesting indeed (I won`t pretend to understand all of it, I don`t) it seems to be on about the structure more than the mechanism of how we see though (from the bits I can understand).

 

the part about it being similar to an extension of the brain tissue is interesting though!

other than that, the whole idea behind sight and we see things seems unfathomable to me. our pixel ressolution is massive! and the processing is mili seconds, all through a little "nerve"!

how can that be? what`s the event sequence behind it all?

Ok try
