A principal odor map unifies diverse tasks in olfactory perception
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 ...

Recurrent cortical circuits implement concentration-invariant odor coding
Science, 2018 Representing the identity of a smell We still don't know how odors retain their identities over a range of concentrations. Working in mice, Bolding and Franks simultaneously recorded spiking activity from neurons in the olfactory bulb and piriform cortex,

The Role of Odor-Evoked Memory in Psychological and Physiological Health
Brain Sciences, 2016 This article discusses the special features of odor-evoked memory and the current state-of-the-art in odor-evoked memory research to show how these unique experiences may be able to influence and benefit psychological and physiological health.

Sensory characteristics analysis for typical odor emission sources [PDF]
Archives of Environmental Protection, 2021 The hedonic tone of an environmental odor is a powerful predictor of annoyance. Pertinent field surveys combined with laboratory analysis of landfill, pharmaceutical factories and rubber factories have been conducted, with the purpose of obtaining a ...

Odor Emotional Quality Predicts Odor Identification [PDF]
Chemical Senses, 2015 It is commonly agreed upon a strong link between emotion and olfaction. Odor-evoked memories are experienced as more emotional compared with verbal, visual, and tactile stimuli. Moreover, the emotional quality of odor cues increases memory performance, but contrary to this, odors are poor retrieval cues for verbal labels.

Predicting odor perceptual similarity from odor structure [PDF]
Flavour, 2013 To understand the brain mechanisms of olfaction we must understand the rules that govern the link between odorant structure and odorant perception. Natural odors are in fact mixtures made of many molecules, and there is currently no method to look at the molecular structure of such odorant-mixtures and predict their smell. In three separate experiments,

Behavioral and Neurobiological Convergence of Odor, Mood and Emotion: A Review
Frontiers in Behavioral Neuroscience, 2020 The affective state is the combination of emotion and mood, with mood reflecting a running average of sequential emotional events together with an underlying internal affective state. There is now extensive evidence that odors can overtly or subliminally
