Effect of lidocaine on olfactory perception in humans [PDF]

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.

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 ...

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.

Olfactory perception of chemically diverse molecules [PDF]

BMC Neuroscience, 2016
ABSTRACT Background: 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 ...

Stimulus Driven Functional Transformations in the Early Olfactory System

Frontiers in Cellular Neuroscience, 2021
Olfactory stimuli are encountered across a wide range of odor concentrations in natural environments. Defining the neural computations that support concentration invariant odor perception, odor discrimination, and odor-background segmentation across a ...

Neural Basis of Olfactory Perception [PDF]

Annals of the New York Academy of Sciences, 2009
The neural basis of olfactory information processing and olfactory percept formation is a topic of intense investigation as new genetic, optical, and psychophysical tools are brought to bear to identify the sites and interaction modes of cortical areas involved in the central processing of olfactory information.

Olfactory training in the elderly: impact on olfactory perception, cognition and well-being.

, 2023
International audienceNormal aging is characterized by a global decline in sensory acuity and cognition, including olfactory perception. In France, 30% of people over 60 years old suffer from olfactory deficits, that negatively impact physical and mental

Olfactory perception is positively linked to anxiety in young adults [PDF]

, 2012
Olfactory abilities show a high degree of inter-individual variability and this could be partly related to personality differences. Here, in two studies, we tested a potential link between personality dimensions and olfactory perception.

Opposite regulation of inhibition by adult-born granule cells during implicit versus explicit olfactory learning

eLife, 2018
Both passive exposure and active learning through reinforcement enhance fine sensory discrimination abilities. In the olfactory system, this enhancement is thought to occur partially through the integration of adult-born inhibitory interneurons resulting

A hit map-based statistical method to predict best ligands for orphan olfactory receptors: Natural key odorants versus "lock picks"

, 2022
S.85-97Smell is a multidimensional chemical sense. It creates a perception of our odorous environment by integrating the information of a plethora of volatile chemicals with other sensory inputs, emotions and memories.
