Summary

The perception of odors exerts powerful influences on moods, decisions, and actions. Indeed, odor perception is a major driving force underlying some of the most important human behaviors. How is it that the simple inhalation of airborne molecules can exert such strong effects on complex aspects of human functions? Certainly, just like in the case of vision and audition, the perception of odors is dictated by the ability to transduce environmental information into an electrical “code” for the brain to use. However, the use of that information, including whether or not the information is used at all, is governed strongly by many emotional and cognitive factors, including learning and experiences, as well as states of arousal and attention. Understanding the manners whereby these factors regulate both the perception of odors and how an individual responds to those percepts are paramount for appreciating the orchestration of behavior.
