> when our eyes are open, our vision accounts for two-thirds of the electrical activity of the brain – a full 2 billion of the 3 billion firings per second – which was the finding of neuroanatomist R.S. Fixot in a paper published in 1957 .. half of all neural tissue deals with vision in some way.
> According to John Medina in his book Brain Rules, in the fight for more neural real estate that’s going on between our olfactory cortex and the visual cortex, vision is winning. He writes: “about 60 percent of our smell-related genes have been permanently damaged in this neural arbitrage, and they are marching toward obsolescence at a rate fourfold faster than any other species sampled.”
I'm visually impaired/low vision with some neurological visual issues but I pass as sighted and this is really it. Vision takes so much work - I'm definitely going to describe it as a 'greedy' sense + steal your bandwidth analogy.
