…or rather, the visual system. Cause you can’t really talk about the optic nerve unless you talk about the rest of the eye along with it.
We humans rely pretty heavily on vision as a species. At least, being able to see is a lot more important to our daily lives than, say, being able to smell. But the visual system is, in many ways, surprisingly simple. In many OTHER ways, it’s confusing as all get out. I will do my best. 🙂
So, I’m going to start with this: an image is going to come in. It will get flipped BACKWARD. It will hit the first cells LAST. It will then go along to the back of the brain, and on the way it will get flipped upside down. And then our brain processes it, and everything’s all right. It’s opposite day, my friends!!!
Got it? Good.
