Continuous odor profile monitoring to study olfactory navigation in small animals [PDF]
arXiv, 2023 Olfactory navigation is observed across species and plays a crucial role in locating resources for survival. In the laboratory, understanding the behavioral strategies and neural circuits underlying odor-taxis requires a detailed understanding of the animal's sensory environment. For small model organisms like C. elegans and larval D.

What the odor is not: Estimation by elimination [PDF]
Phys. Rev. E 104, 024415 (2021), 2019 Olfactory systems use a small number of broadly sensitive receptors to combinatorially encode a vast number of odors. We propose a method of decoding such distributed representations by exploiting a statistical fact: receptors that do not respond to an odor carry more information than receptors that do because they signal the absence of all odorants ...

SPME Method Optimized by Box-Behnken Design for Impact Odorants in Reduced Alcohol Wines
Foods, 2018 The important sampling parameters of a headspace solid-phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS) procedure such as the extraction temperature, extraction time, and sample volume were optimized to quantify 23 important ...

Segregation of Unknown Odors From Mixtures Based on Stimulus Onset Asynchrony in Honey Bees
Frontiers in Behavioral Neuroscience, 2019 Animals use olfaction to search for distant objects. Unlike vision, where objects are spaced out, olfactory information mixes when it reaches olfactory organs.

Learning to predict target location with turbulent odor plumes [PDF]
arXiv, 2021 Animal behavior and neural recordings show that the brain is able to measure both the intensity of an odor and the timing of odor encounters. However, whether intensity or timing of odor detections is more informative for olfactory-driven behavior is not understood. To tackle this question, we consider the problem of locating a target using the odor it

Odors: from chemical structures to gaseous plumes [PDF]
, 2020 We are immersed within an odorous sea of chemical currents that we parse into individual odors with complex structures. Odors have been posited as determined by the structural relation between the molecules that compose the chemical compounds and their ...

Science is perception: what can our sense of smell tell us about ourselves and the world around us? [PDF]
, 2010 Human sensory processes are well understood: hearing, seeing, perhaps even tasting and touch—but we do not understand smell—the elusive sense. That is, for the others we know what stimuli causes what response, and why and how. These fundamental questions

Odorous and pungent attributes of mixed and unmixed odorants [PDF]
Perception & Psychophysics, 1990 In order to explore functional properties of the olfactory and common chemical senses as well as their relation to the total nasal sensation experienced, various concentrations of two pungent odorants were presented alone and in the presence of different backgrounds of the other irritant. Stimuli comprised formaldehyde (at 1.0, 3.5, 6.9, and 16.7 ppm),

Simultaneous Sampling of Flow and Odorants by Crustaceans can Aid Searches within a Turbulent Plume
Sensors, 2013 Crustaceans such as crabs, lobsters and crayfish use dispersing odorant molecules to determine the location of predators, prey, potential mates and habitat.
