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:
“The greatest part of each day, each year, each lifetime is made up of small, seemingly insignificant moments. Those moments may be cooking dinner...relaxing on the porch with your own thoughts after the kids are in bed, playing catch with a child before dinner, speaking out against a distasteful joke, driving to the recycling center with a week’s newspapers. But they are not insignificant, especially when these moments are models for kids.”
—Barbara Coloroso (20th century)
“To me the sole hope of human salvation lies in teaching Man to regard himself as an experiment in the realization of God, to regard his hands as God’s hand, his brain as God’s brain, his purpose as God’s purpose. He must regard God as a helpless Longing, which longed him into existence by its desperate need for an executive organ.”
—George Bernard Shaw (1856–1950)
