The olfactory cortex encompasses several anatomically distinct regions each hypothesized
to provide differential representation and processing of specific odors. Studies exploring …

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 …

Odor information arrives first in the main olfactory bulb and is then broadcasted to the
olfactory cortices and striatum. Downstream regions have unique cellular and connectivity …

Understanding of the olfactory neural circuits has progressed beyond analysis of how odor
information from the external environment is processed in the brain. While spatially …

Spatial and temporal activity patterns of olfactory bulb projection neurons underlie the initial
representations of odors in the brain. However, olfactory perception ultimately requires the …

Odors are initially encoded in the brain as a set of distinct physicochemical characteristics
but are ultimately perceived as a unified sensory object—a" smell." It remains unclear how …

A core function of the olfactory system is to determine the valence of odors. In humans,
central processing of odor valence perception has been shown to take form already within …

In primary sensory cortices, there are two main sources of excitation: afferent sensory input
relayed from the periphery and recurrent intracortical input. Untangling the functional roles of …

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

The mammalian olfactory cortex is commonly considered critical for odor information
processing and perception. It is becoming increasingly apparent, however, that the olfactory …
