Olfactory coding in the perception of semiochemicals
Journal of Chemical Ecology, 1988Information processing in the olfactory pathway underlying the perception of semiochemicals by insects is discussed. Both the chemical message for mates and the message for food consist of blends of chemicals. Olfactory receptors in an insect species are tuned to the detection of those compounds which comprise such chemical messages for that species ...

Retronasal Olfactory Function in Patients With Smell Loss but Subjectively Normal Flavor Perception
Laryngoscope, 2020 Objectives The human sense of smell constitutes the main part of flavor perception. Typically, patients with loss of olfactory function complain of diminished perception during eating and drinking.

Grounding Semantics in Olfactory Perception
Proceedings of the 53rd Annual Meeting of the Association for Computational Linguistics and the 7th International Joint Conference on Natural Language Processing (Volume 2: Short Papers), 2015Multi-modal semantics has relied on feature norms or raw image data for perceptual input. In this paper we examine grounding semantic representations in olfactory (smell) data, through the construction of a novel bag of chemical compounds model. We use standard evaluations for multi-modal semantics, including measuring conceptual similarity and cross ...

Genetics of Olfactory Perception
2003Interest in the nature and bases of olfactory function in human and nonhuman populations has stimulated considerable research activity (Kohl and Francoeur, 1995; Griff and Reed, 1995; Kodis, 1998; Laurent, 1999). Studies of individual differences in olfactory characteristics have focused on measures related to experience (Castle, Van Toller and ...

External nares and olfactory perception
Experientia, 1979Lower vertebrates have more widely separated external nares than higher forms and are thus better adapted to utilize olfactory tropotaxis, or stereolfaction, than higher vertebrates which, on account of their flexible necks, must utilize klinotaxis. Snakes and tubenosed bats break the rule on account of their specialized life styles.

Unilateral olfactory perception and magical ideation
Schizophrenia Research, 2001We assessed olfactory detection thresholds and discrimination abilities in 40 healthy right-handers (20 women and 20 men). All subjects were also required to complete the Magical Ideation (MI) scale, a well-validated 30-item schizotypy inventory. Over both nostrils, we found elevated thresholds for subjects with high MI scores (at or above the median ...

Influence of olfactory dysfunction on the perception of food
European Archives of Oto-Rhino-Laryngology, 2019Eating-related problems are among the most frequent issues in olfactory impairment, causing a noticeable loss of quality of life for some of the affected persons. To what extent olfactory dysfunction impacts on the sensory perception of food is less explored.

Initial mechanisms basic to olfactory perception
American Journal of Otolaryngology, 1983Animal experimentation has proposed three mechanisms at the olfactory mucosa that may underlie olfactory discrimination. First, the olfactory receptor cells appear selectively tuned to different odorants. Second, in a gas chromatographic-like process, the molecules of different odorants appear to be distributed in different sorption patterns across the

Introversion-Extraversion and Dimensions of Olfactory Perception
Perceptual and Motor Skills, 1987A possible relationship between odor perception and introversion-extraversion was explored. 195 subjects completed Eysenck's Introversion-Extraversion Scale and rated strength, familiarity, and pleasantness of four odors. Zero-order correlations were examined and the data were factor analyzed.
