Let me get this straight: you are trying to create a credible model of
vision and you don't even know the basic literature? 

What's the matter, can't find the answer to your question in 
Scientific American or Trends in Neuroscience? I guess you'll just
have to read the 1500-2000 original source articles like the rest of
us did in order to have some understanding of the field.
