Receptor arrays optimized for natural odor statistics [PDF]
, 2016 Natural odors typically consist of many molecules at different concentrations. It is unclear how the numerous odorant molecules and their possible mixtures are discriminated by relatively few olfactory receptors. Using an information-theoretic model, we show that a receptor array is optimal for this task if it achieves two possibly conflicting goals ...

Odor Descriptor Understanding through Prompting [PDF]
arXiv, 2022 Embeddings from contemporary natural language processing (NLP) models are commonly used as numerical representations for words or sentences. However, odor descriptor words, like "leather" or "fruity", vary significantly between their commonplace usage and their olfactory usage, as a result traditional methods for generating these embeddings do not ...

The True Odor of the Odorous House Ant [PDF]
American Entomologist, 2015 More than 13,000 ant species have been formally described, yet the general public recognizes only two main categories: red ants and black ants. This system has some limitations, so there has been increased effort to provide additional sensory information for ant identification, including the sense of smell.

Othello-dor: Racialized Odor In and On Othello
Multicultural Shakespeare, 2020 For Shakespearean scholars, the subject of scent in his work has remained relatively lukewarm to discussion. Shakespeare’s use of smell is not only equal to that of his other senses, but smell’s uniquely historical record both on and off the stage ...

Frontiers in Neuroscience, 2022 Distinct brain regions are known to be associated with various emotional states. Cortical activity may be modulated by emotional states that are triggered by flavors during food intake.

Normalized neural representations of natural odors [PDF]
, 2016 The olfactory system removes correlations in natural odors using a network of inhibitory neurons in the olfactory bulb. It has been proposed that this network integrates the response from all olfactory receptors and inhibits them equally. However, how such global inhibition influences the neural representations of odors is unclear.

Odor Emotionality Affects the Confidence in Odor Naming [PDF]
Chemical Senses, 2005 Previous research has demonstrated that participants are overconfident in the veracity of their odor identifications. This means that their confidence expressed as subjective probabilities is, on average, higher than the actual proportion of correct odor identifications.

Odor Canopy: A Method for Comfortable Odorant Delivery in MRI
Chemical Senses, 2021 Abstract Functional magnetic resonance imaging (fMRI) has become the leading method for measuring the human brain response to sensory stimuli. However, olfaction fMRI lags behind vision and audition fMRI for 2 primary reasons: First, the olfactory brain areas are particularly susceptible to imaging artifacts, and second, the olfactory ...

Olfactory systems and neural circuits that modulate predator odor fear
Frontiers in Behavioral Neuroscience, 2014 When prey animals detect the odor of a predator a constellation of fear-related autonomic, endocrine, and behavioral responses rapidly occur to facilitate survival.

, 2020 We perceive smells as perduring complex entities within a distal array that might be conceived of as smellscapes. However, the philosophical orthodoxy of Odor Theories has been to deny that smells are perceived as having a distal location.
