NEUROTRANSMITTERS are the brain chemicals that communicate information throughout our brain and body. They relay signals between nerve cells, called âneurons.â The brain uses neurotransmitters to tell your heart to beat, your lungs to breathe, and your stomach to digest.here are two kinds of neurotransmitters â INHIBITORY and EXCITATORY. Excitatory neurotransmitters are not necessarily exciting â they are what stimulate the brain. Those that calm the brain and help create balance are called inhibitory.
