Olfaction: The Sense of Smell

This guide is a review of the literature and vetted online resources on the subject of smell. It is designed, as the name of the series implies, to put the reader ‘on target.’ This and other recent Tracer Bullets are available in print and also online from Science Reference Services at: http://www.loc.gov/rr/scitech/tracer-bullets/tbs.html

New NIDCD research offers intriguing clues into the role of smell in food preference

From a  National Institute on Deafness and Other Communications Disorders (NIDCD) press release

The role of smell behavior is now yielding intriguing clues in how we decide what’s good to eat.

[Smell] behavior is the result of a dedicated subsystem of specialized olfactory receptors in the nose and neural circuits in the brain whose job it is to associate an incoming odor with food that’s safe to eat. The NIDCD-funded study was conducted by Steven Munger, Ph.D., at the University Of Maryland School of Medicine in Baltimore, Md., and an international team of researchers.

Now, a recent paper published online in the journal Current Biology shows that the behavior is the result of a dedicated subsystem of specialized olfactory receptors in the nose and neural circuits in the brain whose job it is to associate an incoming odor with food that’s safe to eat. The NIDCD-funded study was conducted by Steven Munger, Ph.D., at the University Of Maryland School of Medicine in Baltimore, Md., and an international team of researchers.

“Scientists are beginning to see the olfactory system not as a solitary unit, but as a collection of subsystems, some of them well known and some of them only recently described,” says Munger. Each of these subsystems is distinguished by the location of its sensory neurons in the nasal cavity, the kinds of receptors and signaling mechanisms it uses, the region of the brain’s olfactory bulb it signals, and likely the ultimate destination of those signals in the brain’s olfactory cortex. This helps explain why the role of smell is so broad among mammals.
