[HTML][HTML] Odor identity can be extracted from the reciprocal connectivity between olfactory bulb and piriform cortex in humans

B Iravani, A Arshamian, M Lundqvist, LM Kay… - Neuroimage, 2021 - Elsevier
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) …

Semantic context‐dependent neural representations of odors in the human piriform cortex revealed by 7T MRI

T Okumura, I Kida, A Yokoi, T Nakai… - Human Brain …, 2024 - Wiley Online Library
Olfactory perception depends not only on olfactory inputs but also on semantic context.

Odor representations from the two nostrils are temporally segregated in human piriform cortex

GN Dikeçligil, AI Yang, N Sanghani, T Lucas, HI Chen… - Current Biology, 2023 - cell.com
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 the primary …

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

F Nordén, B Iravani, M Schaefer, AL Winter… - PLoS …, 2024 - journals.plos.org
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 …

Continuous spatial representations in the olfactory bulb may reflect perceptual categories

B Auffarth, A Gutierrez-Galvez, S Marco - Frontiers in Systems …, 2011 - frontiersin.org
In sensory processing of odors, the olfactory bulb is an important relay station, where odor
representations are noise-filtered, sharpened, and possibly re-organized. An organization …

Functional sub-circuits of the olfactory system viewed from the olfactory bulb and the olfactory tubercle

M Yamaguchi - Frontiers in Neuroanatomy, 2017 - frontiersin.org
Understanding of the olfactory neural circuits has progressed beyond analysis of how odor
