Quality-space theory in olfaction
Quality-space theory (QST) explains the nature of the mental qualities distinctive of perceptual states by appeal to their role in perceiving. QST is typically described in terms of the mental qualities that pertain to color. Here we apply QST to the olfactory modalities. Olfaction is in various respects more complex than vision, and so provides a useful test case for QST. To determine whether ...
متن کاملImplausibility of the vibrational theory of olfaction.
The vibrational theory of olfaction assumes that electron transfer occurs across odorants at the active sites of odorant receptors (ORs), serving as a sensitive measure of odorant vibrational frequencies, ultimately leading to olfactory perception. A previous study reported that human subjects differentiated hydrogen/deuterium isotopomers (isomers with isotopic atoms) of the musk compound cyclo...
متن کاملStatus of the Vibrational Theory of Olfaction
The vibrational theory of olfaction is an attempt to describe a possible mechanism for olfaction which is explanatory and provides researchers with a set of principles which permit predictions allowing for structure-odor relations. Similar theories have occurred several times throughout olfactory science; this theory has again recently come to prominence by Luca Turin, who suggested that inelas...
متن کاملAgainst Vibration Theory of Olfaction BSE656A - Neurobiology
Olfaction is the sense of smell. It is the phenemenon of receptors detecting certain properties about the molecules that are known as odorants.The perception of an odour is the result of an extraordinary complex cascade of events. The very first steps of this perception involves the interaction of chemicals with our olfactory neurons[7]. Odour is a property that depends on several highly variab...
متن کاملAn Algebraic Description of Stereochemical Correspondence ( dynamic stereochemistry / group theory )
It is shown that a stereochemical correspondence between two molecular systems can be represented by a commuting diagram of the point groups and permutation groups involved. The effect of the diagrammatic condition on the mappings of the cosets, double cosets, subgroup lattice, and double coset algebra determined for the two molecular systems by point group to permutation group homomorphisms is...
