)What does the brain do?
The brain controls most of the functions in your body. It sends out signals to tell different parts of your body what to do. It also gets signals from your eyes, your skin and other body parts to tell it what is going on around you. Your brain controls your reactions and it also controls your emotions.
Your brain sends signals through nerve cells and these signals are electrical, but your brain cells can also send signals as chemicals. These chemicals are called neurotransmitters because they send signals between nerve cells. Neurotransmitters travel from one cell to another and tell nerve cells what to do.
