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 ...

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 ...

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

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.

Olfactory networks: from sensation to perception
Current Opinion in Genetics & Development, 2011Olfactory networks, comprised of sensory neurons and interneurons, detect and process changes in the chemical environment to drive animal behavior. Recent studies combining genetics with behavioral analyses and imaging in worms, flies and mice have revealed new insights into the mechanisms of olfaction. In this discussion, we focus on three interesting

Distorted olfactory perception: A systematic review
Acta Oto-Laryngologica, 2012The sense of smell provides people with valuable input from the chemical environment around them. The human sense of smell generally fails in three ways; one is an intensity reduction and the other two are the quality of changes. Smell disorders can be classified into central or peripheral depending on their origin.

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 ...

Chapter 5. Olfactory perception
2012From a functional perspective odor perception involves the detection and recognition of complex chemical blends against an ever-changing chemical background. This chapter examines one account of how this might occur using an object recognition approach (ORA).

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 ...
