Technical Tuesday Smell
The word olfactory means “relating to the sense of smell”. The human olfactory system is one of the oldest sensory systems in the history of mammals. A chemical sensor, the olfactory system not only detects food and other scents, it also influences behavior.
In the nose, (the nasal conchae) contains more than 100 million olfactory receptor cells. Thus, it is not surprising that as many as 2 million people in the U.S. have some kind of olfactory dysfunction, ranging from minor to severe.
That being said, most of us have an efficient sense of smell. The only time it shuts down is during REM (Rapid Eye Movement) sleep. During this time, you can’t smell anything you normally would. That’s why fire alarms are so important – during REM sleep you wouldn’t be able to smell smoke!

Quote
of the Day:
“Smell is a potent wizard that
transports you across thousands of miles and all the years you have lived. The
odors of fruits waft me to my southern home, to my childhood frolics in the
peach orchard. Other odors, instantaneous and fleeting, cause my heart to
dilate joyously or contract with remembered grief. Even as I think of smells,
my nose is full of scents that start awake sweet memories of summers gone and
ripening fields far away.”
