Your brain is like a big city with different neighborhoods. Each neighborhood has a different job to do. The cortical area is like one of these neighborhoods. It's a part of your brain that helps you think, move, feel things, and see things.
Think of it this way: Your brain is like a city, and the cortical area is like one of the buildings in that city. Inside that building, different teams work together to help you do different things. If you need to move your arm, one team will help you do that. If you need to think about something, another team will help you with that.
The cortical area also helps you make sense of what you see and hear. When you look at something, the image goes to your eyes, and then the information travels to the cortical area. The area helps you understand what you're seeing and figure out what to do about it.
So, think of the cortical area as a special part of your brain that helps you do lots of important things, like moving, thinking, and seeing. Just like a building in a city, it has lots of different teams working together to make sure everything runs smoothly.
