The structure of human olfactory space [PDF]

open access: yesarXiv, 2009
We analyze the psychophysical responses of human observers to an ensemble of monomolecular odorants. Each odorant is characterized by a set of 146 perceptual descriptors obtained from a database of odor character profiles. Each odorant is therefore represented by a point in highly multidimensional sensory space. In this work we study the arrangement of

Conservation of Olfactory Avoidance in Drosophila Species and Identification of Repellents for Drosophila suzukii. [PDF]

open access: yes, 2015
Flying insects use olfaction to navigate towards fruits in complex odor environments with remarkable accuracy. Some fruits change odor profiles substantially during ripening and related species can prefer different stages.

Evaluation of the key odorants of foods by dilution experiments, aroma models and omission.

open access: yesChemical Sensors, 2001
The state of the art in aroma analysis is reviewed with emphasis on aroma-recombination studies using synthetic blends of odorants (aroma models) which have been prepared on the basis of analytical data.

Scenting the Hedonic Connection: Exploring the Impact of Subjective Olfactory Dysfunction on Depressive Symptoms

open access: yesPsyCh Journal, EarlyView.
ABSTRACT Olfaction, often regarded as a unique chemical sensation, plays a pivotal role in shaping our quality of life and mental well‐being. Numerous studies have highlighted the significant relationship between olfactory function and depressive symptoms.

Interrelatedness of Neurocognitive Domain Functioning Between Unprompted and Prompted Identification Testing With Psychophysical Olfactory Evaluation in a Post‐COVID‐19 Cohort

open access: yesWorld Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective Assessment of olfactory function with psychophysical testing requires cognitive demand to correctly pair test odors with remembered scents. Individuals suffering from long‐Corona Virus Disease 2019 (long‐COVID‐19) may develop a decline in neurocognitive performance, which may be concurrent with persistent olfactory dysfunction (OD ...

Odour perception in the codling moth Cydia pomonella L. [PDF]

open access: yes, 2004
The codling moth, Cydia pomonella L. (Lepidoptera: Tortricidae) is a renowned pest in apple, pear and walnut orchards, and its activities are in large guided by volatile odours as sensory cues.

Perceptual blending in odor mixtures depends on the nature of odorants and human olfactory expertise.

open access: yesChemical Sensors, 2012
Our olfactory system is confronted with complex mixtures of odorants, often recognized as single entities due to odor blending (e.g., coffee). In contrast, we are also able to discriminate odors from complex mixtures (e.g., off-odors).

Diet acts on sexual behavior development in a male moth

open access: yesInsect Science, EarlyView.
Drastic changes are observed during sexual maturation characterized by the reproductive system development concomitantly to the sexual behavior ontogenesis. These modifications are under the control of internal and external factors such as food. Knowing that sexual maturation requires considerable energetic investment, diet has been shown to affect ...

Insights on the nutritional ecology of a nocturnal pollinating insect

open access: yesInsect Science, EarlyView.
Nutritional ecology examines the environmental effects on nutritional needs, food intake and foraging behaviors, and the use of nutrients ingested by animals. Among insects, Lepidoptera are often considered opportunistic foragers that visit a wide variety of available flowers, although with some preferences.
