Metaorganismal choline metabolism shapes olfactory perception [PDF]

Journal of Biological Chemistry, 2023
Microbes living in the intestine can regulate key signaling processes in the central nervous system that directly impact brain health. This gut-brain signaling axis is partially mediated by microbe-host-dependent immune regulation, gut-innervating neuronal communication, and endocrine-like small molecule metabolites that originate from bacteria to ...

Olfactory Perception: Receptors, Cells, and Circuits [PDF]

Cell, 2009
Remarkable advances in our understanding of olfactory perception have been made in recent years, including the discovery of new mechanisms of olfactory signaling and new principles of olfactory processing. Here, we discuss the insight that has been gained into the receptors, cells, and circuits that underlie the sense of smell.

Olfactory Perception in Relation to the Physicochemical Odor Space [PDF]

Brain Sciences, 2021
A growing body of research aims at solving what is often referred to as the stimulus-percept problem in olfactory perception. Although computational efforts have made it possible to predict perceptual impressions from the physicochemical space of odors ...

Correlation and agreement of olfactory perception assessed by the Connecticut Chemosensory Clinical Research Center olfactory test and the Brief-Smell Identification Test [PDF]

Brazilian Journal of Otorhinolaryngology, 2022
Introduction: Assessing olfactory perception in olfactory disorders is of utmost importance in therapy management. However, the University of Pennsylvania Smell Identification Test and the Sniffin’ Sticks are the only tests validated in Brazil ...

Neural activity at the human olfactory epithelium reflects olfactory perception

Nature Neuroscience, 2011
Organization of receptive surfaces reflects primary axes of perception. In vision, retinal coordinates reflect spatial coordinates. In audition, cochlear coordinates reflect tonal coordinates. However, the rules underlying the organization of the olfactory receptive surface are unknown.

Olfactory perception of chemically diverse molecules [PDF]

BMC Neuroscience, 2016
ABSTRACTBackground: Understanding the relationship between a stimulus and how it is perceived reveals fundamental principles about the mechanisms of sensory perception. While this stimulus-percept problem is mostly understood for color vision and tone perception, it is not currently possible to predict how a given molecule smells.

Noradrenergic effects on olfactory perception and learning [PDF]

Brain Research, 2019
We here review modulation of olfactory guided behavioral tasks by noradrenaline. In this review we focus on modulation of the main olfactory system in adult rodents. We detail behavioral paradigms commonly used and discuss how sensory perception and learning can be measured using these paradigms.

Measuring the olfactory bulb input-output transformation reveals a contribution to the perception of odorant concentration invariance

Nature Communications, 2017
Humans and animals recognize an odorant across a range of odorant concentrations, but where in the olfactory processing pathway this invariance is generated is unclear.

Effect of lidocaine on olfactory perception in humans

International Journal of Applied and Basic Medical Research, 2018
The effect of local anesthesia to the nasal mucosa on olfactory acuity is the subject of some debate. This study was aimed to investigate the effect of local anesthesia on olfactory perception.Six healthy participants, five males and one female, were chosen from the academic population of Cardiff University.
