Noradrenergic inputs from the locus coeruleus to anterior piriform cortex and the olfactory bulb modulate olfactory outputs Norepinephrine play critical roles in regulating olfactory behaviors, but the precise circuits and mechanisms underlying this function remain unclear. Here, authors show how LC–aPC...
This could be the consequence of a dysfunctional epileptogenic network that extends beyond the hippocampus and affects other structures, including the piriform cortex. To test this hypothesis, we evaluated the olfactory function with the Sniffin' Sticks test in 32 patients with mesial temporal lobe ...

Fifteen participants with normal olfactory function performed a localization task with air‐puff stimuli, phenylethyl alcohol (PEA; rose odor), or a combination thereof while being scanned. The ability to localize PEA to either nostril was at chance. Yet, its presence significantly improved the ...

olfactory cortex. These structures include (a) theanterior olfactory nucleus(AON), (b) theolfactory tubercle(poorly developed in humans), (c) the prepiriform cortex, (d) the pirform cortex (a major olfactory discrimination region), (e) theperiamygdaloid cortex(a region contiguous with the ...
We previously found that adult mouse olfactory tubercle (OT), which belongs to the olfactory cortex and ventral striatum, has functional domains that represent odour-induced motivated behaviours, and that c-fos induction occurs mainly in the anteromedial domain of OT following learned odour-induced ...
