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.hether the result of synaptic transmission will be excitatory or inhibitory depends on the type of neurotransmitter used and the ion channel receptors they interact with.
