Additionally, neurotransmitters chemically link the brain and spinal cord with the rest of your body: muscles, organs, and glands. Thus, our brain is not only an array of wires (nerve cells/neurons) but also a highly evolved chemical soup (neurotransmitters). Neurotransmitters affect every cell, tissue, and system in your body.
Excitatory synaptic transmission uses a neurotransmitter called L-glutamate. This is a common amino acid used throughout the body to build proteins (it is also used as a flavour enhancer-mono-sodium glutamate!!!). However, in the CNS it is the major excitatory neurotransmitter.n addition to L-glutamate and GABA, there are a whole range of other neurotransmitters and their receptors (acetylcholine, dopamine, serotonin and many others) that also perform vital functions in the central nervous system, some of which are excitatory and some of which are inhibitory.
