Large-scale analysis of perceptual odor data
- Psychology, BiologyFlavour
- 2014
A database consisting of several hundred perceptual descriptors for several thousand odors is accumulated by merging data from different publicly available sources to give a better idea of the dimensionality of the odor space, and of how to approach studies of structure-odor relationships.
Odor Stimuli: Not Just Chemical Identity
- BiologyFront. Physiol.
- 2019
The underlying principles of physics are summarized and the experimental and theoretical Neuroscience literature is reviewed, focusing on the aspects that are relevant to animals’ physiology and behavior, by bringing the physical principles behind odor plume landscapes to the fore.
Understanding the Odour Spaces: A Step towards Solving Olfactory Stimulus-Percept Problem
- BiologyPloS one
- 2015
A graphical method is developed to find the similarity between perceptual descriptors; which is intuitive and can be used to identify perceptual classes and found a significant overlap between the spatial positioning of the clustered molecules in the physico-chemical and perceptual spaces.
Odour perception: A review of an intricate signalling pathway
- Biology, Psychology
- 2016
This review aims to describe the main intricate steps of olfactory processing in mammals, some of which remain unclear, and the close associations and overlapping nature of these steps.
Multivariate statistical analysis of a large odorants database aimed at revealing similarities and links between odorants and odors
- Biology, Psychology
- 2018
A computational analysis using odor descriptions of the odorants present in Flavor-Base 9th Edition (2013) yielded results suggesting an interesting and promising way of using computational approaches to help decipher olfactory coding.
Mosaic activity patterns and their relation to perceptual similarity: open discussions on the molecular basis and circuitry of odor recognition
- Biology, PsychologyJournal of neurochemistry
- 2014
A short introduction to the functioning of olfactory systems from transduction of odorant stimuli into electrical signals in sensory neurons to the anatomical and functional organization of the networks involved in neural representation of odors in the central nervous system is provided.
Smelly primes – when olfactory primes do or do not work
- Psychology, BiologyFront. Psychol.
- 2014
Recommendations and ideas for a future research agenda and applications for olfactory priming are formulating based on a brief overview of the priming literature from social psychology and from Olfactory perception science.
A compact olfactometer for IMS measurements and testing human perception
- BiologyInternational Journal for Ion Mobility Spectrometry
- 2018
This work presents a compact olfactometer able to produce controlled continuous odor stimuli from three individual channels based on aspiration ion mobility spectrometry (aIMS) and demonstrates that it can use different odor components to produce continuous, stable output flows with controlled concentrations.
Pleasantness and trigeminal sensations as salient dimensions in organizing the semantic and physiological spaces of odors
- PsychologyScientific Reports
- 2018
Findings suggest that salient trigeminal features, in conjunction with pleasantness, are involved in detecting relevant emotional stimuli, and modify the way organisms categorize smells.

Continuous Spatial Representations in the Olfactory Bulb may Reflect Perceptual Categories
- Biology, PsychologyFront. Syst. Neurosci.
- 2011
This work applies a statistical analysis on 2-deoxyglucose images taken over the entire bulb of glomerular layer of the rat to see how the recognition of odors in the nose is translated into a map of odor quality in the brain, and indicates that perceptual qualities could be represented as continuous spatial codes of the olfactory bulb glomerulus population.
A Large-Scale Analysis of Odor Coding in the Olfactory Epithelium
- Biology, PsychologyThe Journal of Neuroscience
- 2011
These studies revealed extraordinary diversity, but also bias, in odorant recognition by the OSN, and thus OR, repertoire, indicating that most OSNs are narrowly tuned to detect a subset of odorants with related structures and often related odors, but that the repertoire also includes broadly tuned components.
A Molecular Vocabulary for Olfaction a

Olfactory research is entering a new phase, in which molecular mechanisms are being revealed that go considerably beyond traditional concepts. New ways of characterizing these mechanisms are needed,…
Relating Sensor Responses of Odorants to Their Organoleptic Properties by Means of a Biologically-Inspired Model of Receptor Neuron Convergence onto Olfactory Bulb

The results suggest that convergence mapping combined with IR absorption spectra may be an appropriate method to capture perceptual characteristics of certain classes of odorants.
Humans and Mice Express Similar Olfactory Preferences
- Biology, PsychologyPloS one
- 2009
It is shown that odor pleasantness rating in humans and investigation time in mice were both correlated with the physicochemical properties of the molecules, suggesting that olfactory preferences are indeed partly engraved in the physicochemistry structure of the odorant.
Distributed representation of chemical features and tunotopic organization of glomeruli in the mouse olfactory bulb
- BiologyProceedings of the National Academy of Sciences
- 2012
Using a sensitive probe, the glomerular response to large numbers of odorants at single glomerulus resolution is analyzed and it is found that the representation of chemical features is spatially distributed in the olfactory bulb with no discernible chemotopy.
Chemotopic odorant coding in a mammalian olfactory system
- BiologyThe Journal of comparative neurology
- 2007
When glomerular activity patterns are viewed relative to the overall level ofglomerular activation, the patterns accurately predict the perception of odor quality, thereby supporting the notion that spatial patterns of activity are the key factors underlying that aspect of the olfactory code.
Modular representations of odorants in the glomerular layer of the rat olfactory bulb and the effects of stimulus concentration
- BiologyThe Journal of comparative neurology
- 2000
It is suggested that changes in modular glomerular activity patterns could underlie altered odor perception across odorant concentrations, and they provide additional support for a combinatorial, spatially based code in the olfactory system.
In search of the structure of human olfactory space.
- BiologyFrontiers in systems neuroscience
- 2011
It is argued that odorants densely sample a two-dimensional curved surface embedded in the multidimensional sensory space, thereby providing surrogates for olfactory sensory space and only 12% of experimental variance cannot be explained by curved surfaces of substantially small dimensionality.
