This friend has now pointed out that the distortion of images handled by

Things are even more distorted past V1.

The following figure (Connolly and Van Essen 1984) shows the mapping of
the visual field (A) on the LGN (B) and the striate cortex (C) in
monkey. Note that the representation of the central 5 degrees (shaded
areas) in the visual field occupies about 40 % of the cortex. "
I'm disappointed that you guys, especially Bob M, aren/t responding to
this. It just might be important to how the brain succeeds in perceiving
images, while computers are such a failure.
Mike,
Have you ever considered that it is completely meaningless to look at
the layout of wires coming from the retina and refer to the images
carried by those wires as "distorted"?
If I get a bizarre new keyboard for my computer in which all the keys
are in the reverse of their usual positions, will all the ideas that I
express then suddenly become reversed? If all the keys were a different
shape, with some being really huge and others quite small, will my ideas
become distorted?
That is why you are getting no response.
