VIDEO EXCERPTS: . . . What happens, your brain shuts down your visual input for roughly the time it takes for you to move. Like 50 milliseconds, 20th of a second, and for that time vision is shut down.

Now then you should have these constant annoying cuts, just like in a movie, where you have two or three frames of black. That would be annoying, so what the brain does is really clever. Just like post-editing, it cuts out that movie, and then it splices it together, so it looks like you see all the time.

[...] I move, and I open my eyes, it looks like I see continuously. This is a con job done by my brain, because my eyes move. If I were to sit and put a camera at the output of my eyes, I would constantly see this huge motion. Just like you buy a video camera, and you yank it around violently, you would throw up.

[...] You may remember from high school, there's a blind spot. So if I close my left eye now, there's over here roughly in this part of my visual field the spot that's yay big. But I don't see anything there that's a hole. Why?

It has to do with the wiring. So that's the place in my eye where the wires that make up the optic nerve leave the eye. So at that place there are no pixels -- if you want in modern language, there are no photoreceptors. There's just no information there, there should be a [blank] hole.

[...] Why is it we don't see many pixels that are sort of black? Why don't we trade in our visual equipment? Well, because our brain hides it from us. It cleverly interpolates it, and this is not done in the retina. This is done high up in the brain...
