Olfactory Perception in Relation to the Physicochemical Odor Space

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

Retronasal perception of odors

Physiology & Behavior, 2012
We perceive odors orthonasally during sniffing; in contrast, we perceive odors retronasally during eating when they enter the nose through the pharynx. There are clear differences between orthonasal and retronasal olfaction in neuronal processing and perception, so that these two pathways convey two distinct sensory signals.

Odors and the Perception of Hygiene

Perceptual and Motor Skills, 2005
Although certain odors, such as lemon, are commonly associated with cleanliness and positive hygiene, empirical assessment of such associations for other odors and attributes is generally lacking. Moreover, differences between men and women in such associations have not been established.

A principal odor map unifies diverse tasks in olfactory perception [PDF]

Science, 2023
Mapping molecular structure to odor perception is a key challenge in olfaction. We used graph neural networks to generate a principal odor map (POM) that preserves perceptual relationships and enables odor quality prediction for previously ...

Odor perception in alexithymic patients

Psychiatry Research, 2010
Alexithymia is characterized by a marked inability to identify feelings and emotional states and some studies have documented sensorial perception in response to visual or auditory cues in this disease. Although olfaction is well known for its emotional correlates, the perception of olfactory stimulations has not been previously investigated.

The Impact of Stress on Odor Perception

Perception, 2017
The olfactory system and emotional systems are highly intervened and share common neuronal structures. The current study investigates whether emotional (e.g., anger and fear) and physiological (saliva cortisol) stress responses are associated with odor identification ability and hedonic odor judgments (intensity, pleasantness, and unpleasantness ...

Self-perception of breath odor

The Journal of the American Dental Association, 2001
Bad breath, also known as halitosis, is a common concern for millions of people. Yet there is almost no reliable way for people to properly assess their breath odor. While many develop faulty perceptions about having bad breath that affect their entire lives, others who have halitosis are unaware of their condition.The authors discuss the issues ...
