Quick Reference

Releasing serotonin; also activated by or responding to serotonin, this extended usage being widespread but consistently rejected by the English physiologist Sir Henry Hallet Dale (1875–1968), who coined the suffix -ergic, and by many other authorities. The term applies especially to nerve fibres such as those of the raphe nuclei of the medulla oblongata, the area postrema, and the locus coeruleus that use serotonin as a neurotransmitter and that project to the cerebral cortex, limbic system, thalamus, and cerebellum. Compare adrenergic, cholinergic, dopaminergic, GABAergic, noradrenergic. [From serotonin + Greek ergon work + -ikos of, relating to, or resembling]
