We know that flies can perceive changes in the world around them up to seven times faster than a human - we appear slow to them.
I'm wondering how this is possible. Is it just that information travelling is limited by the speed of light, and it has a shorter distance to travel across a flies brain? Or is there some metabolic or other biological reason for this?
(It would be great to speed up a human's brain - but I'm sure there are a million reasons why that is not possible).
My question is: Is the reason that flies can perceive things faster because their brains are smaller?
