Document Summary
L2 visual dominant species think about what vision does? it creates a model of external space the info we start with is mosaic as patches of light over the retina. Most of the brain is taken up by vision. When you compress the data: visual system keeps only the most important look at the retina and the amount of info projected onto it 10^10 bits per sec. Vision is a great example computer or mechanical vision systems has made huge strides. We know a lot about how we would make a visual system. 1 or 200 rod cells drive a glanglion cells the average of the action is what goes to the optic nerve you have a million ganglion cells per eye and they fire 100hz. When they get really complex like ours it is not all about a one way flow of information. What we say is driven from the other direction.
