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.
Whether 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.Different neurotransmitters can be very similar in structure but can have profoundly different functions.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.
