The standard model for molecular recognition of an odorant is that receptor sites discriminate by molecular geometry as evidenced that two chiral molecules may smell very differently. However, recent studies of isotopically labeled olfactants indicate that there may be a molecular vibration-sensing component to olfactory reception, specifically in the spectral region around 2300 cm(-1). Here, we present a donor-bridge-acceptor model for olfaction which attempts to explain this effect. Our model…

Testing odorant-receptor interaction theories in humans through discrimination of isotopomers

A duo-trio discrimination experiment conducted on human subjects is reported on, testing isotopomer pairs that have recently been shown to be differentially encoded in the honeybee brain.

An explicit electron-vibron model for olfactory inelastic electron transfer spectroscopy

The vibrational theory of olfaction was posited to explain subtle effects in the sense of smell inexplicable by models in which molecular structure alone determines an odorant's smell. Amazingly,

Vibrational Detection of Odorant Functional Groups by Drosophila melanogaster

The response of Drosophila to these odorants, which parallels their perception in humans, supports the hypothesis that odor character is encoded in odorant molecular vibrations, not in the specific shape-based activation pattern of receptors.

Exploring the Mechanism of Olfactory Recognition at the Initial Stage by Modeling the Emission Spectrum of Electron Transfer

It is revealed that the emission spectra (after Gaussian convolution) can be acted as odor characteristic spectra and the emission spectrum of ET was able to reasonably interpret the similar bitter-almond odors among hydrogen cyanide, benzaldehyde and nitrobenzene.

Differential Electrophysiological Responses to Odorant Isotopologues in Drosophilid Antennae123

The results strongly suggest that Drosophilid olfactory receptors are activated by molecular vibrations differentiating similarly sized and shaped odorants in vivo, yielding sufficient differential information to drive behavioral choices.

How Far Does a Receptor Influence Vibrational Properties of an Odorant?

This work studies the influence of a receptor on the vibrational properties of an odorant in atomistic details as the coupling between electronic degrees of freedom of the receptor and the vibrations of the odorant is the key parameter of the vibrationally-assisted electron transfer.

Differential Odour Coding of Isotopomers in the Honeybee Brain

Honeybee’s olfactory system discriminates between isotopomers of the same odorant, suggesting that other features, such as molecular vibrations, may contribute to odour signal transduction.

Honeybees (Apis mellifera) learn to discriminate the smell of organic compounds from their respective deuterated isotopomers

Testing honeybees using the proboscis extension reflex learning in a differential conditioning paradigm shows that honeybees readily learn to discriminate hydrogen-based odorants from their deuterated counterparts and supports the idea that intra-molecular vibrations may contribute to odour discrimination.

Single-Neuron Comparison of the Olfactory Receptor Response to Deuterated and Nondeuterated Odorants.

The results support the conclusion that if mammals can perceive deuterated odorants differently, the difference arises from the receptor-independent steps of olfaction.



Molecular vibration-sensing component in Drosophila melanogaster olfaction

It is reported that flies not only differentiate between isotopic odorants, but can be conditioned to selectively avoid the common or the deuterated isotope, which supports the existence of a molecular vibration-sensing component to olfactory reception.

A spectroscopic mechanism for primary olfactory reception.

The evidence presented here suggests that olfaction, like colour vision and hearing, is a spectral sense, and that inelastic electron tunnelling is the mechanism for biological transduction of molecular vibrations.

Could humans recognize odor by phonon assisted tunneling?

A novel proposal suggests receptors are actuated by inelastic electron tunneling from a donor to an acceptor mediated by the odorant, and provides critical discrimination, and is tested using the swipe card model.

Is the olfactory receptor a metalloprotein?

A hypothesis in which metal ions play an important role for odorant recognition is described and a “shuttlecock” mechanism for the possible structural change in ORs upon odorant binding is proposed, involving membrane penetration of the 4–5 loop after residue charge neutralization by metal ion binding.

This work takes up and extended an old idea according to which vertebrate olfactory receptors detect odorants by their molecular vibrations, and proposes that the detection mechanism is inelastic electron tunnelling, and calculates the spectra of structurally diverse odorants belonging to various odor categories.

Olfaction is a chemical sense, not a spectral sense

The discrimination of normal and deuterated odorants by flies is a clear and convincing finding, but such isotope effects do not prove that the animals are sensing infrared molecular vibrations using inelastic electron tunneling spectroscopy (IETS).

Classical conditioning and retention in normal and mutantDrosophila melanogaster

By changing the conditioned discrimination paradigm of Quinn et al. (1974) from an instrumental procedure to a classical (Pavlovian) one, strong learning in type flies is demonstrated and conditioned avoidance still was measurable at least three hours after training.
