Odor perception is inherently subjective. Previous work has shown that odorous molecules
evoke distributed activity patterns in olfactory cortices, but how these patterns map on to …

In the olfactory system, environmental chemicals are deconstructed into neural signals and
then reconstructed to form odor perceptions. Much has been learned about odor coding in …

Most real-world odors are complex mixtures of distinct molecular components. Olfactory
systems can adopt different strategies to contend with this stimulus complexity. In elemental …

The olfactory system has a particularly difficult task: unlike vision or sound, the number of
elementary stimuli—the odors—seems to be almost infinite. Furthermore, airborne odors …

It is widely presumed that odor quality is a direct outcome of odorant molecular structure, but
increasing evidence suggests that learning, experience, and context play important roles in …

Olfactory perception and behaviors critically depend on the ability to identify an odor across
a wide range of concentrations. Here, we use calcium imaging to determine how odor …

Olfaction is fundamentally distinct from other sensory modalities. Natural odor stimuli are
complex mixtures of volatile chemicals that interact in the nose with a receptor array that, in …

Ongoing sensory input is critical for shaping internal representations of the external world.
Conversely, a lack of sensory input can profoundly perturb the formation of these …

Categorization allows organisms to efficiently extract relevant information from a diverse
environment. Because of the multidimensional nature of odor space, this ability is …

It is widely presumed that odor quality is a direct outcome of odorant structure, but human
studies indicate that molecular knowledge of an odorant is not always sufficient to predict …
