Summary
Neuromodulation is the process when a neuron uses one or more neurotransmitters to regulate populations of neurons, unlike in classical synaptic transmission, where a presynaptic neuron directly influences a postsynaptic partner.
Neuromodulators secreted by a small group of neurons diffuse through large areas of the nervous system, affecting multiple neurons. Major neuromodulators in the central nervous system include dopamine, serotonin, acetylcholine, histamine, and norepinephrine.
