The Vomiting Center of The Brain
This integrates the emetic response. This is the area in which "a final decision is made" about whether to evoke an emetic response or not. This decision is based heavily on the information which the CTZ relays to the vomiting center, but also the chemoreceptors in the GI tract, the information sent to the vomiting center by the vestibular system, and higher order centers located in the cortex. The vomiting center is not a discrete or specific place in the brain, but rather an area consisting of many nuclei, axons, and receptors that together cause the physical changes necessary to induce vomiting. Also, emesis can occur by direct neural stimulation of the vomiting center.

Famous quotes containing the words center and/or brain:
“My center is giving way, my right is in retreat; situation excellent. I shall attack.”
—Ferdinand Foch (1851–1929)
“The analogy between the mind and a computer fails for many reasons. The brain is constructed by principles that assure diversity and degeneracy. Unlike a computer, it has no replicative memory. It is historical and value driven. It forms categories by internal criteria and by constraints acting at many scales, not by means of a syntactically constructed program. The world with which the brain interacts is not unequivocally made up of classical categories.”
—Gerald M. Edelman (b. 1928)
