I agree, there's so much about the brain we don't understand, plus whole sections overlap or process multiple sources. Nothing is simple in the brain! In terms of the amount of your grain required or dedicated to each input this says nothing. However, the statement was: > There is more brain input from vision than any other input possible I guess we could compare the nerves that lead from the sense organs. Again from wikipedia: > Each human optic nerve contains between 770,000 and 1.7 million nerve fibers > In humans, there are on average 30,000 nerve fibers within the cochlear nerve so again, at least an order of magnitude more nerve connections from the sense organs to the brain. I think this backs up the original statement. Interestingly the number of nerve connections from the cochlear are greater than the number of raw sensory inputs, but the eye is quite the opposite. I know the input to the brain is more of a differential coding between colours than raw data from the cells.
