Predicting odor perceptual similarity from odor structure [PDF]
Flavour, 2013 To understand the brain mechanisms of olfaction we must understand the rules that govern the link between odorant structure and odorant perception. Natural odors are in fact mixtures made of many molecules, and there is currently no method to look at the molecular structure of such odorant-mixtures and predict their smell. In three separate experiments,

Odorant-sensing cell micropatterns for odor discrimination
Biosensors and Bioelectronics: X, 2023 A technology that can effectively distinguish between various odorants with high sensitivity and selectivity has numerous applications ranging from water quality testing to disease diagnosis. Here, we report a cell-based odorant-sensing display that utilizes Sf21 cells expressing odorant receptors, co-receptors, and a calcium-sensitive fluorescent ...

Odor Threshold Determination of 53 Odorant Chemicals [PDF]
Journal of Environmental Conservation Engineering, 1969 In order to assist in assessing potential odor problems arising from chemical manufacturing operations, the odor thresholds of 53 commercially important odorant chemicals have been determined using a standardized and defined procedure. The odor threshold data previously available have shown wide variation reflecting the diversity of procedures and ...

Odors Cue Memory for Odor-Associated Words [PDF]
Chemosensory Perception, 2009 The ability of odors to cue vivid and emotionally intense memories is well-known. However, the majority of research has focused on the extent to which odors can act as environmental cues to memory, where odors are presented alongside the stimuli to be remembered, rather than the extent to which pre-existing associations between odor and odor-related ...
