Reply	Alby says: There have certainly been experiments in which people were paid to wear glasses designed to "flip" the image and after long periods wearing these glasses their vision returned to normal as the brain compensated. This of course became a problem when they removed the glasses but the brain did again compensate.I would imagine that damage to the visual cortex significant to impact on this particular aspect of vision would also create more significant visual problems.  (1 vote) average rating:4 Tags: transport, human body.

Reply	retch says: Having long used a single-lens reflex 6x9cm camera, I can confirm that the eye/brain very quickly learns to compensate for left-right flips as well, and can snap in and out of it instantly. The same goes for color balance when using filters, like daylicht-tungsten, on the lens of an SLR.  (no votes) Tags: transport, human body.

Reply	Anonymous says: I had an interesting experience several years ago. I foolishly took a chipmunk away from a cat, and it bit me, of course. Sunk it's teeth into the fleshy part of my hand near the base of the thumb. I watched it do this, but at the same time had a vision of the teeth sinking into my hand as if seen from the inside. I could "see" the whiteness of the tooth. Later, in bed, reflecting on the experience, I realized this internal "vision" of the bite did not corespond to the actual vision of the incedent. It was upside down. As I interpret it, this internal vision was still run through the normal visual circuitry which reversed an image that hadn't been reversed in the first place, not having passed through the lens of the eye. rb  (1 vote) average rating:1 Tags: transport, human body.

Reply	Jon Webb says: The "up-down flipping" of imagery is not really an act by the brain. It is simply the way the imagery is presented and interpreted. It is inherent in the structure of the brain, just as, say, a mirror performs a left-right reversal.  (no votes) Tags: transport, human body.

Reply	Suricou Raven says: Anonymous appears to be lacking in basic scientific knowledge - how does he think he saw an image other than through his eyes?  (no votes) Tags: transport, human body.
