I am interested in providing a little information on the human physiological
underpinnings which make it so much easier to extract information from an
image than from a table of data describing the image. I recall reading
somewhere that the bandwidth of the visual cortex dwarfs that of the cerebral
cortex, and that this is the explanation. I have read Yehouda Harpaz'
treatise on Human Cognition* and understand that 1) I don't know much about
human cognition, and 2) the processes of data acquisition and comprehension
are two different animals.
However simple-minded it may be, I seek an approximate answer to the
What are the bandwidths of the human visual and creebral cortices in, say,
I would be most appreciative of any references or answers to this question.
Thanks very much.
