Increased understanding of the early stages of olfaction has lead to a renewed interest in the
higher brain regions responsible for forming unified 'odor images' from the chemical …

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

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 …

The primary olfactory (or piriform) cortex is a trilaminar paleocortex that is thought to
construct unified “odor images” from the odor components identified by the olfactory bulb …

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 …

Highlights•Odor information is encoded in the distributed activity of piriform cortex
neurons.•Piriform uses complementary coding strategies to represent odor identity and …

Olfactory perception and its underlying neural mechanisms are not fixed, but rather vary over
time, dependent on various parameters such as state, task, or learning experience. In …

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 …

The orbitofrontal cortex (OFC) has been characterized as a higher‐order, multimodal
sensory cortex. Evidence from electrophysiological and behavioral studies in the rat has …

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 …
