What are brain cells?

Brain cells are special helpers inside your head that let you think, feel, and learn new things.

Imagine your brain is like a busy city, and brain cells are like tiny workers in that city. Some of them send messages to each other, just like how people talk on the phone or shout across the street. These workers have different jobs, some help you remember your favorite song, others help you ride a bike without falling.

Think of brain cells as little messengers in a relay race. When you see something cool, like a rainbow, one cell gets excited and passes the message to another cell, and so on until your whole brain knows about the rainbow!

Sometimes these workers team up, imagine a group of friends passing notes together to solve a puzzle.

If brain cells are working too hard, like when you stay up late reading a book, they might feel sleepy. That’s why you sometimes need a nap after learning something new!
