chemoreceptor trigger zone

The area of the medulla oblongata that communicates with the vomiting centre, which is located in the floor of the 4th ventricle and receives vagal afferents or stimulated directly by apomorphine, cardiac glycosides, ergot compounds, chemotherapeutics, staphylococcal enterotoxin, salicylates, nicotine and other circulating chemicals. In contrast to the adjacent but distinct vomiting centre, the CTZ does not respond to electrical stimulation.
