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 …

Detection and discrimination of odors generally, if not always, occurs against an odorous
background. On any given inhalation, olfactory receptor neurons will be activated by …

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 …

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 …

Background The formation of an odor percept in humans is strongly associated with visual
information. However, much less is known about the roles of learning and memory in …

The stimulus complexity of naturally occurring odours presents unique challenges for central
nervous systems that are aiming to internalize the external olfactory landscape. One …

Background Sensory perception is profoundly shaped by attention. Attending to an odor
strongly regulates if and how it is perceived–yet the brain systems involved in this process …

In awake rodents, the neural representation of olfactory information in the olfactory bulb is
largely dependent on brain state and behavioral context. Learning-modified neural plasticity …

A key function of the sense of smell is to guide organisms towards rewards and away from
dangers. However, because relatively few volatile chemicals in the environment carry …

Sensory systems must represent stimuli in manners dependent upon a wealth of factors,
including stimulus intensity and duration. One way the brain might handle these complex …
