If a neurotransmitter is excitatory, it will increase the likelihood that the neuron will fire action potential. Examples of these types of neurotransmitter are epinephrine and norepinephrine. Inhibitory neurotransmitters – in contrast to ... The existence of multiple types of receptors for dopamine was first proposed in 1976. There are at least five subtypes of dopamine receptors, D1, D2, D3, D4, and D5. The D1 and D5 receptors are members of the D1-like family of dopamine receptors, whereas the D2, D3 and D4 receptors are members of the D2-like family.
