Odor concentration invariance by chemical ratio coding [PDF]
Frontiers in Systems Neuroscience, 2008 Many animal species rely on chemical signals to extract ecologically important information from the environment. Yet in natural conditions chemical signals will frequently undergo concentration changes that produce differences in both level and pattern ...

Stimulus Control of Odorant Concentration: Pilot Study of Generalization and Discrimination of Odor Concentration in Canines. [PDF]
Animals (Basel), 2021 Despite dogs’ widespread use as detection systems, little is known about how dogs generalize to variations of an odorant’s concentration. Further, it is unclear whether dogs can be trained to discriminate between similar concentration variations of an ...

Concentration invariant odor coding [PDF]
, 2017 Humans can identify visual objects independently of view angle and lighting, words independently of volume and pitch, and smells independently of concentration.

Chemical Engineering Transactions, 2016 Odor annoyance is the second most important nuisance in Europe. So, the knowledge of the odor concentration is very important to assess the odor impact on the environment. In Europe, EN 13725 regulates the method to measure the odor concentration.

The influence of stimulus concentration and odor intensity on relaxing and stimulating perceived properties of odors [PDF]
Food Quality and Preference, 2021 International audienceIt is generally assumed that intensity can be used as a proxy of the arousing properties of odors: the more concentrated an odorant, the more intense an odor and the more stimulating and the less relaxing the odor.

Odor Concentration Change Coding in the Olfactory Bulb. [PDF]
eNeuro, 2019 AbstractDynamical changes in the environment strongly impact our perception. Likewise, sensory systems preferentially represent stimulus changes, enhancing temporal contrast. In olfaction, odor concentration changes across consecutive inhalations (ΔCt) can guide odor source localization, yet the neural representation ofΔCthas not been studied in ...

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 ...

The Potential Contribution of VOCs on Ambient Air Odor
Asian Journal of Atmospheric Environment, 2021 In order to evaluate the potential contribution of VOCs on ambient air odor in roadside, urban, suburban and mountainous environments, the odor activity values (OAVs) of 66 VOCs were calculated using the environmental concentrations and the odor ...

Understanding odor information segregation in the olfactory bulb by means of mitral and tufted cells. [PDF]
PLoS ONE, 2014 Odor identification is one of the main tasks of the olfactory system. It is performed almost independently from the concentration of the odor providing a robust recognition.
