Ctz in medulla
WebThe chemoreceptor trigger zone is a bilateral set of centers in the brainstem lying under the floor of the fourth ventricle. Electrical stimulation of these centers does not induce vomiting, but application of emetic drugs does - if and only if the vomition centers are intact. http://www.vivo.colostate.edu/hbooks/pathphys/digestion/stomach/vomiting.html
