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 …

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 …

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 …

How do airborne plumes of molecules docking on olfactory receptors emerge as conscious
odors in the brain? How are they interpreted in space, time, and biological meaning? And …

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

The major problem in olfactory neuroscience is to determine how the brain discriminates
one odorant from another. The traditional approach involves identifying how particular …

The sense of smell has been traditionally assumed to be different from other sensory
modalities in that odors are encoded perceptually, without a semantic component. Recent …

Human olfactory perception is notoriously unreliable, but shows substantial benefits from
visual cues, suggesting important crossmodal integration between these primary sensory …

Cholinergic and GABAergic projections from the horizontal diagonal band (HDB) and medial
preoptic area (MCPO) of the basal forebrain to the olfactory system are associated with odor …

Studies of patients with focal brain injury indicate that smell perception involves caudal
orbitofrontal and medial temporal cortices, but a more precise functional organization has …
