The human olfactory bulb communicates perceived odor valence to the piriform cortex in the gamma band and receives a refined representation back in the beta band
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 …

Parallel odor processing by two anatomically distinct olfactory bulb target structures
The olfactory cortex encompasses several anatomically distinct regions each hypothesized
to provide differential representation and processing of specific odors. Studies exploring …

Anterior olfactory cortices differentially transform bottom-up odor signals to produce inverse top-down outputs
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 …

[HTML][HTML] Odor identity can be extracted from the reciprocal connectivity between olfactory bulb and piriform cortex in humans
Neuronal oscillations route external and internal information across brain regions. In the
olfactory system, the two central nodes—the olfactory bulb (OB) and the piriform cortex (PC) …

Piriform cortex takes sides: temporally-segregated odor representations from ipsilateral and contralateral nostrils within a single sniff
The human olfactory system has two discrete channels of sensory input, arising from
olfactory epithelia housed in the left and right nostrils. Here, we asked whether primary …
