The test persons must fulfill certain requirements, for example regarding their sensitivity of odor perception.

Gilles Laurent and colleagues showed that oscillatory synchronization has an important functional role in odor perception.

If odor perception followed rules similar to those of color perception, and if it relied exclusively on derived parameters (such as carbon chain length), then mixtures would be perceived as intermediates of their components.

Her work also deals with how language can affect odor perception and her laboratory has empirically demonstrated the first instance of olfactory illusions created by words alone.

Changing odor hedonic perception through emotional associations in humans.

The nature of sniffing regulates odor perception in humans and in fact, in humans, a single sniff is often sufficient for optimal odor perception.

These examples have been supported by empirical studies (see above) and have provided insights into methods whereby humans may change their sniffing strategies to modulate odor perception.

What to Do The first step is to realize that there is a problem in odor perception, particularly for older people, who may not recognize a gradual loss.

These phenomena indicate that odor perception cannot be as easily visualized in a low-dimensionality space as other sensory modalities.

The latter technique gives information about volatile organic compounds but the correlation between analytical results and actual odor perception is not direct due to potential interactions between several odorous components.
