What is Structure of white matter?

White matter is like a bunch of superhighways inside your brain that help messages travel fast between different parts.

Imagine your brain is a big city, and all the places in the city, like schools, shops, and homes, need to talk to each other. The white matter is like the roads connecting these places. It helps the messages (which are like little cars) zoom from one part of the city to another.

White matter is made up of special fibers, kind of like long, twisty noodles. These noodles are covered in a fatty layer, which makes them really fast at sending messages, just like how wearing socks helps you run faster on the playground!

These fibers group together into bundles, making big highways that connect different parts of your brain. When these highways work well, you can think quicker and learn easier.

If something happens to these highways, like if they get clogged or broken, it might be harder for messages to travel, and you might feel a little slower in thinking or moving. But with practice and time, new highways can even form!
