olfactory receptors

olfactory receptors

Etymology: L, olfactus, sense of smell, recipere, to receive
bipolar nerve cells located in the nasal epithelium. Axons of the cells are receptors of the olfactory nerve.

Chemoreceptors of insects mainly consist of olfactory receptors (ORs) and gustatory receptors (GRs), which are located in the dendritic membrane of neurons.
The cultivated cells contained several typical olfactory receptors, which are proteins that bind together smell molecules and are located on olfactory receptor cells lining the nose.
Olfactory receptors reveal a seven-transmembrane domain structure and are specifically responsible for the recognition and G protein-mediated transduction of odorant signals [18].
Interestingly, researchers have found that the exquisite human sensitivity of our olfactory receptors to detect the smell of sulfur is due to another element --copper," he said.
That's because the sense of smell is processed through olfactory receptors that are directly connected to the limbic system, the brain's ancient emotion center.
Inspired by this biological example, this project aims at integrating natural olfactory receptors into two state-of-the-art technologies: Ion Channel-Coupled Receptors (ICCRs) and single-walled Carbon NanoTube-Field Effect Transistors (swCNT-FETs).
In general, St are usually the most common and numerous structures on insect antennae and presumed to function as olfactory receptors in many insects (Bleeker et al.
It was about 5 pm, I dragged myself from under the rockslides of sleep after a long dreary night of mind-numbing video gaming when I woke up to an odour that prickled my olfactory receptors.
Research also shows that a dog's and cat's sense of smell is a thousand times more sensitive than that of a human's and that a dog has more than 220 million and a cat more than 80 million olfactory receptors in their nose, while a human has only 5 million.
The team found that African bush elephants (Loxodonta africana) carry about 2,000 genes for smell sensors, or olfactory receptors.
describe the so-called "space of olfactory perception" is that despite the large number of different kinds of olfactory receptors, and much larger variety of possible smell molecules to stimulate them, this space is surprisingly low-dimensional - so low-dimensional they say, that the best way we have to classify mixtures is in terms of pleasantness.
