How the brain budgets what we perceive in the world around us to maximize efficiency, explains gothemind
This brings us to the second grand solution that makes perception possible.

Copyright Rebecca Schwarzlose Yet brain maps alone cannot solve the problem of perceiving a big world with one measly brain. There is still too much detailed information reverberating in the world around us and only so much energy and headspace to go around. As a result, your brain maps cannot faithfully represent all the information striking the surfaces of your skin, the backs of your eyeballs, and the deep recesses of your ears.
Ideally, you would be able to see things equally well out of the corner of your eye as you do at your center of gaze. But you need more neurons, and more connections between those neurons, to represent fine details. In order to see equally well in your visual periphery as you do at your center of gaze, the visual maps in your brain would have to be thirteen times larger. If this change sounds innocuous, think again. It would make your visual brain maps alone too large to fit inside your skull.
