Document Summary
Odor stimuli in mouth reaches the olfactory mucosa via the retronasal route. Taste of most compounds is influences by olfactory. few (like msg) are not. Pheromones- olfactory linked to the four f of survival (feed, fornicate, flee, fight) Messenger chemicals called pheromones can control these basic behaviours. Weak evidence supporting that these messenger chemicals re unconsciously at work in humans. Manyy other species (snakes, mokeys) have vomeronasal organ (vno) and accessory olfactory bulb (aob). In humans, some research supports the existence of cranial nerve 0 in humans (exists in many other species). It projects from nasal cavity to septal nuclei and other brain areas known to regulate sexual behavior. May be involved in human pheremonal control of sexual arousal. Stern and mcclinton doubtful experiment because nobody can replicate it. Suggests pheromones are responsible for menstrual synchrony in humans. Secretions form armpits were wiped on other women"s lips. Secretion from those at beginning of cycle led to shorter cycle in recipients.
