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.

Parts of the Neurons Neurons have a very special shape with different parts that allow them to connect to other neurons.Learn more
Networks of the Neurons Neurons communicate information through a network of trillions of these connections.Learn more
