And inside the brain, those electrical signals are basically used to create an image that is right side up. Now, the last portion I'd like to talk about is something called the phobia.

So we have a very high concentration of cones in the fobia compared to our rods. And that's exactly why on the fovia, we have the sharpest image being formed.
