The Area postrema is a part of the brain. The lower end of the ala cinerea is crossed by a narrow translucent ridge, the funiculus separans, and between this funiculus and the clava, is a small tongue-shaped area, the area postrema.
The Area postrema, one of the circumventricular organs, detects toxins in the blood and acts as a vomit inducing center. It connects to the Nucleus of the Solitary Tract and other autonomic control centres in the brainstem.
