Neural Communication

The nervous system is a complex network of billions of neurons, or individual nerve cells. These cells send and receive messages while you are awake or asleep. They also allow different parts of your body to communicate, including your muscles and your glands. Nerve cells are the primary system of communication within the brain, and between the brain and the rest of the body.
