What is the brain made of?
Surface of the Brain
The top layer of the brain, or cortex, has deep grooves because it is crumpled up. The brain’s surface is a lot bigger than if it were snooth. This makes it possible to fit more brain area inside our heads.
Cells of the brain
The gray matter of the brain is made up of billions of nerve cells, Called neurons. The brain is gray because the cell bodies are gray. These calls are connected together in a network and talk to each other.
