The main problem with sensory processing is the difficulty in relating sensory input to physiological responses and perception. This is especially problematic at higher levels of processing, where complex cues elicit highly specific responses. In olfaction, this relationship is particularly obfuscated by the difficulty of characterizing stimulus statistics and perception. The core questions in olfaction are hence the so-called stimulus problem, which refers to the understanding of the stimulus… Expand

Large-scale analysis of perceptual odor data
It is a general problem in sensory processing to understand which aspect of the sensory input is relevant to perception. In olfaction, because of the high-dimensionality, and the difficulty in… Expand
Odor Stimuli: Not Just Chemical Identity
TLDR
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. Expand
Understanding the Odour Spaces: A Step towards Solving Olfactory Stimulus-Percept Problem
TLDR
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. Expand
Odour perception: A review of an intricate signalling pathway
The perception of odours is the result of the complex processing of a signal, which initiates at peripheral receptors and ends in the brain. Along this pathway, olfactory signal processing proceeds… Expand
Multivariate statistical analysis of a large odorants database aimed at revealing similarities and links between odorants and odors
The perception of odor is an important component of smell; the first step of odor detection, and the discrimination of structurally diverse odorants depends on their interactions with olfactory… Expand
Using a bio-inspired surface resonance plasmon electronic nose for fundamental research on human olfaction
Abstract Electronic noses are artificial devices designed to detect and classify odors, used for many industrial applications but they can also be a tool for fundamental research on the chemical… Expand
Mosaic activity patterns and their relation to perceptual similarity: open discussions on the molecular basis and circuitry of odor recognition
TLDR
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. Expand
Smelly primes – when olfactory primes do or do not work
TLDR
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. Expand
Predicting the response of olfactory sensory neurons to odor mixtures from single odor response
TLDR
The analysis suggests that the odor response space is 3-dimensional, and predicts that the dose-response curve of an odor receptor can be obtained, in most cases, from three primary components with specific properties. Expand
A compact olfactometer for IMS measurements and testing human perception
Production of easily controllable and measurable odor stimuli is needed when studying human olfaction, olfaction-related physiology and psychological reactions to odors. Controlled odor producing… Expand

Odor representations in the mammalian olfactory bulb
TLDR
It is suggested that current evidence points toward a representation that is spatially organized at the inputs but later distributed, with the spatial organization not being used for much computation in the first stage of the olfactory pathway. Expand
Olfactory perceptual learning: the critical role of memory in odor discrimination
TLDR
It is argued that the initial odorant feature extraction/analytical processing is not behaviorally/consciously accessible, but rather is a first necessary stage for subsequent cortical synthetic processing which in turn drives olfactory behavior. Expand
Quantification of odor quality.
TLDR
This review scrutinizes how psychophysicists and others have measured quality and offers criteria for useful techniques, including nonsubjective techniques that have high sensitivity, can have counterparts in infrahuman research, are suitable to examine individual differences and yield non-negotiable answers with potential archival value.

Continuous Spatial Representations in the Olfactory Bulb may Reflect Perceptual Categories
TLDR
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.

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,… Expand
A Large-Scale Analysis of Odor Coding in the Olfactory Epithelium
TLDR
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.

PSYCHOLOGIC DIMENSIONS IN THE PERCEPTION OF EVERYDAY ODORS: PLEASANTNESS AND EDIBILITY
ABSTRACT Different studies have reported that when a wide range of odors are assessed at a similar odor intensity, the hedonic dimension (pleasantness) is the most salient. Multivariate statistical… Expand
Relating Sensor Responses of Odorants to Their Organoleptic Properties by Means of a Biologically-Inspired Model of Receptor Neuron Convergence onto Olfactory Bulb
We present a neuromorphic approach to study the relationship between the response of a sensor/instrument to odorant molecules and the perceptual characteristics of the odors. Clearly, such… Expand
Humans and Mice Express Similar Olfactory Preferences
TLDR
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. Expand
Distributed representation of chemical features and tunotopic organization of glomeruli in the mouse olfactory bulb
TLDR
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. Expand
