How does an eye reconstruct an image?

[QUOTE="andrewkirk, post: 6832821, member: 265790"] Unless you are asking what [I]part [/I]of the brain processes the image (and I don't think you are asking that) this question has no answer. It is like asking "where is my sadness?" The brain uses the information it gets from the pixel pattern on the retina to construct an [I]experience [/I]for you, and that experience is what we call "seeing". It has a spatial or geometric nature to it and makes us feel that the object we see is "over there" (and countless philosophical tomes have discussed and debated what we mean by "over there"). But the experience is not an object in space, any more than other experiences such as sadness, fear or curiosity are. Even pain in a specific part of the body, that we think of as very spatially specific - eg to the left knee, is actually an experience created by our brain, based on signals it receives through nerves from that part of the body. That's why local anesthetic techniques such as "ring blocks" work. If the signal from your finger where the doctor is digging out a deeply embedded splinter, can't get to the brain, you feel no pain.
