Brains are made of brain cells. If you haven’t learned about cells yet, that’s okay. Think of each cell as a worker in a factory. The factory is you. Brain cells have different jobs. Some get messages from places like your skin or eyes. Some send messages to make your muscles move or to make you sweat. Some connect cells to each other. Brain cells let us think, remember, feel and imagine.

You need a microscope to see brain cells. Here’s a picture of brain cells that was taken through a microscope

The scientists used color to make the cells easier to see.

Scientists still have a lot to learn about how brains work. Maybe you will help find the answers someday.
