The brain actively works to stabilize visual input on the retina to ensure a consistent view of the world during movement.

“So the brain works really hard to mostly stabilize the image of the world on your retina and of course you're moving through the world so you can't stabilize everything. But the more you can stabilize most of the time, the better you can see.”

The visual system, specifically the retina, is an extension of the central nervous system that developed from the brain.

“As many of you have heard me say before on this and other podcasts, your eyes, and in particular your neural retinas, are part of your central nervous system. They are part of your brain. They are the only part of your brain that sits outside the cranial vault.”
