On the principle of odor interaction
Abstract The present study was designed to explore the principle of odor interaction for two malodorous organic sulphides mixed at various levels of perceived intensity. The two odorants were chosen to be qualitatively similar, and mixtures of the two should produce a homogeneous percept of odor quality. Both the odor components and the mixtures were

Odor-intensity interaction in binary and ternary mixtures [PDF]
Eight subjects scaled the overall perceived odor intensity of binary and ternary mixtures of the odorous substances pyridine, acetone, and ethyl acrylate. The results concerning basic principles of additivity for binary mixtures comply with those of earlier studies.

Odor is a very serious problem worldwide. Thus, odor prediction research has been conducted consistently to help prevent odor. Odor substances that are complex odors are known, but complex odors and odor substances do not have a linear dependence.

Odorant-odorant metabolic interaction, a novel actor in olfactory perception and behavioral responsiveness [PDF]
AbstractIn the nasal olfactory epithelium, olfactory metabolic enzymes ensure odorant clearance from the olfactory receptor environment. This biotransformation of odorants into deactivated polar metabolites is critical to maintaining peripheral sensitivity and perception.

h(odor): Interactive Discovery of Hypotheses on the Structure-Odor Relationship in Neuroscience [PDF]
From a molecule to the brain perception, olfaction is a complex phenomenon that remains to be fully understood in neuroscience. Latest studies reveal that the physico-chemical properties of volatile molecules can partly explain the odor perception. Neuroscientists are then looking for new hypotheses to guide their research: physico-chemical descriptors

Odorants of Different Chemical Classes Interact with Distinct Odorant Binding Protein Subtypes [PDF]
The ligand profile for three odorant binding proteins (OBPs) of the rat have been determined using a large number of odorous compounds from different chemical classes. To evaluate the binding spectra of distinct subtypes, all OBPs were produces in Escherichia coli as recombinant His-tagged fusion proteins.

Background Odors Modulate N170 ERP Component and Perception of Emotional Facial Stimuli
Successful social interaction relies on the accurate decoding of other peoples’ emotional signals, and their contextual integration. However, little is known about how contextual odors may lead to modulation of cortical processing in response to facial ...

A Mathematical Model of the Olfactory Bulb for the Selective Adaptation Mechanism in the Rodent Olfactory System. [PDF]
To predict the odor quality of an odorant mixture, the interaction between odorants must be taken into account. Previously, an experiment in which mice discriminated between odorant mixtures identified a selective adaptation mechanism in the olfactory ...

Taste + odor interactions in compound aversion conditioning [PDF]
In three experiments with rats, taste + odor interactions in compound aversion conditioning were investigated. In Experiment 1, two odors (0.02% almond and 0.02% orange) were compared on single-element odor aversions, taste (denatonium) potentiated odor aversions, and potentiated odor aversions following taste extinction.
