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.

, 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.

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 ...

Sensing Dog Brain Reactions to Smell by AI Speckle Pattern Analysis
Journal of Biophotonics, EarlyView.The setup of our experiment is shown on Labrador, Johny, a canine participant of our research. The schematic of the setup features: green laser, digital camera, source of smell, and computer. Regions of the brain that were tested are highlighted. Note that the hippocampus and amygdala are on both sides of the dog's brain.

Ternary Fingerprints with Reference Odor for Fluctuation-Enhanced Sensing [PDF]
arXiv, 2020 An improved method for Fluctuation Enhanced Sensing (FES) is introduced. We enhanced the old binary fingerprinting method, where the fingerprint bit values were +/- 1, by introducing ternary fingerprints utilizing a reference odor. In the ternary method, the fingerprint bit values are -1, 0, and +1 where the 0 value stands for the situation where the ...

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