An excitatory synapse is a synapse in which an action potential in a presynaptic neuron increases the probability of an action potential occurring in a postsynaptic cell. Neurons form networks through which nerve impulses travel, each neuron often making numerous connections with other cells.
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.
