*''Vamana'' is believed to be controlled by two distinct brain centers - the vomiting center(tractus soitorius and the Chemoreceptor Trigger Zone both located in the Medulla Oblongata. The CTZ is close to the area postrema on the floor of the fourth ventricle and is outside of the blood brain barrier and communicates with the vomiting centre to initiate ''vamana''. The CTZ being outside the blood-brain barrier, and can therefore be stimulated by blood-borne drugs that can stimulate vomiting, or inhibit it.

*''Vamana'' provoked by noxious smells originates in the cerebral cortex (through chemoreceptors in nasal mucosa - ''Ghreya Vamana'').

*Cranial nerves mediate ''vamana'' after gag reflex activation (''Anguli, Kamala nala pravesha'').
