Olfactory perception is initiated by the recognition of odorants by a large repertoire of
receptors in the sensory epithelium. A dispersed pattern of neural activity in the nose is …

Natural odors, generally composed of many monomolecular components, are analyzed by
peripheral receptors into component features and translated into spatiotemporal patterns of …

Despite a remarkably precise spatial representation of odorant stimuli in the early stages of
olfactory processing, the projections to the olfactory (piriform) cortex are more diffuse and …

Current models of odor discrimination in mammals involve molecular feature detection by a
large family of diverse olfactory receptors, refinement of molecular feature extraction through …

A working hypothesis is proposed for piriform cortex (PC) and other olfactory cortical areas
that redefines the traditional functional roles as follows: the olfactory bulb serves as the …

The mammalian piriform cortex receives direct synaptic input from the olfactory bulb and is
likely the locus for the formation of odor percept. It remains unclear how individual cortical …

Much data on the olfactory bulb (OB) indicates that structural characteristics of odorant
molecules are encoded as ordered, spatially consolidated sets of active cells. New results …

The piriform cortex (PCX) is the largest component of the olfactory cortex and is
hypothesized to be the locus of odor object formation. The distributed odorant representation …

Neurons in piriform cortex receive input from a random collection of glomeruli, resulting in
odor representations that lack the stereotypic organization of the olfactory bulb. We have …

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 …
