The representation of odor in olfactory cortex (piriform) is distributive and unstructured and
can only be afforded behavioral significance upon learning. We performed 2-photon …

Odors are well known to elicit strong emotional and behavioral responses that become
strengthened throughout learning, yet the specific cellular systems involved in odor learning …

Neuroscientific models of sensory perception suggest that the brain utilizes predictive codes
in advance of a stimulus encounter, enabling organisms to infer forthcoming sensory events …

Recent proposals have conceptualized piriform cortex as an association cortex, capable of
integrating incoming olfactory information with descending input from higher order …

Olfaction is influenced by contextual factors, past experiences, and the animal's internal
state. Whether this information is integrated at the initial stages of cortical odour processing …

Identification of an object based on its odor alone is inherently difficult, but becomes easier
when other senses provide supporting cues. This suggests that crossmodal sensory input …

Odors activate distributed ensembles of neurons within the piriform cortex, forming cortical
representations of odor thought to be essential to olfactory learning and behaviors. This odor …

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 …

Rodents can learn from exposure to rewarding odors to make better and quicker decisions.
The piriform cortex is thought to be important for learning complex odor associations; …

Rodents can successfully learn multiple novel stimulus–response associations after only a
few repetitions when the contingencies predict reward. The circuits modified during such …
