ELI5: Explain Like I'm 5

Cortical magnification

Well, imagine that your brain is a big factory and it has all these different departments that help you see, hear, and feel things. One of these departments is responsible for helping you see things really clearly, like when you're reading a book or watching a movie.

Now, imagine that this department is a bit like a camera. When you look at something, like a tiny bug on a leaf, the camera in your brain takes a picture of it and sends it to this department. But the picture that the camera takes is really small, like a tiny dot. So, the department needs to make the dot bigger so that you can see the bug more clearly.

This is where cortical magnification comes in. Cortical magnification is like a special machine that this department uses to make things look bigger. It takes the tiny dot of the bug and makes it bigger so that it takes up more space in your brain. This way, you can see the details of the bug more clearly.

The interesting thing is that not everything in your view is magnified the same way. Objects that are smaller, like the bug on the leaf, are magnified more than objects that are bigger, like a tree. This is because your brain needs to focus more on the details of smaller objects to understand what they are.

So, in summary, cortical magnification is like a special machine in your brain that helps you see things more clearly by making them look bigger. It helps you focus on the details of small objects, like bugs, so that you can understand what you're seeing.
