In mammals, the vomeronasal organ, which detects phermones, resides in a bli nd ended pouch within the septum of the nose. Vomeronasal organ-derived signals bypass higher cognitive centers and are processed directly in regions of the amygdala and hypothalamus, which have been implicated in the regulation of innate behaviour, reproductive physiology, and other neuroendocrine response s. Zvn2R1 encodes a human vomeronasal receptor.
