Decomposition of individual components of bio-organic waste: volatile organic compounds and the impact on health and psycho-emotional state

open access: yesRUDN Journal of Ecology and Life Safety, 2023
The study considers the impact on the person’s health and psycho-emotional state of unpleasant odors arising from the storage and accumulation of bioorganic waste, including food waste (meat, poultry, fruits and vegetables) and bird droppings. The survey

Gonadal hormones, but not sex, affect the acquisition and maintenance of a Go/No-Go odor discrimination task in mice [PDF]

open access: yes, 2018
In mice, olfaction is crucial for identifying social odors (pheromones) that signal the presence of suitable mates. We used a custom-built olfactometer and a thirst-motivated olfactory discrimination Go/No-Go (GNG) task to ask whether discrimination of ...

Segregation of Unknown Odors From Mixtures Based on Stimulus Onset Asynchrony in Honey Bees

open access: yesFrontiers 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.

The Wire Is Not the Territory: Understanding Representational Drift in Olfaction With Dynamical Systems Theory

open access: yesTopics in Cognitive Science, EarlyView., 2023
Abstract Representational drift is a phenomenon of increasing interest in the cognitive and neural sciences. While investigations are ongoing for other sensory cortices, recent research has demonstrated the pervasiveness in which it occurs in the piriform cortex for olfaction.

Influence of blood meal on the responsiveness of olfactory receptor neurons in antennal sensilla trichodea of the yellow fever mosquito, Aedes aegypti [PDF]

open access: yes, 2010
In female Aedes aegypti L. mosquitoes, a blood meal induces physiological and behavioral changes. Previous studies have shown that olfactory receptor neurons (ORNs) housed in grooved peg sensilla on the antennae of Ae.

Key Odorants Regulate Food Attraction in Drosophila melanogaster

open access: yesFrontiers in Behavioral Neuroscience, 2017
In insects, the search for food is highly dependent on olfactory sensory input. Here, we investigated whether a single key odorant within an odor blend or the complexity of the odor blend influences the attraction of Drosophila melanogaster to a food ...

Gas Chromatography Olfactometry (GC-O) for the (Semi)Quantitative Screening of Wine Aroma

open access: yesFoods, 2020
This review discusses the different approaches developed by researchers in the last 40 years for the qualitative and semi-quantitative screening of odorants, with special emphasis in wine aroma profiling.

Olfactory sensitivity for six predator odorants in CD-1 mice, human subjects, and spider monkeys. [PDF]

open access: yesPLoS ONE, 2013
Using a conditioning paradigm, we assessed the olfactory sensitivity of six CD-1 mice (Mus musculus) for six sulfur-containing odorants known to be components of the odors of natural predators of the mouse.

Influence of phytoplankton on the water quality of surface water sources and drinking water

open access: yesRUDN Journal of Ecology and Life Safety, 2023
The problem of the appearance of odors in drinking water associated with the development of algae and cyanobacteria in reservoirs of drinking water sources is considered.

Floral and Bird Excreta Semiochemicals Attract Western Carpenter Ants

open access: yesFrontiers in Ecology and Evolution, 2022
Ant colonies have vast and diverse nutritional needs but forager ants have limited mobility to meet these needs. Forager ants would accrue significant energy savings if they were able to sense and orient toward odor plumes of both carbohydrate and ...
