Bioinspired nose sensors employing biological olfactory receptors
are an alternative.
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
The team obtained similar results with 25 other pairs of deuterated/undeuterated compounds when responding to their specific 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.
Researchers who examined olfactory receptors
, the proteins involved in detecting smell, found that African elephants had almost 2,000 olfactory genes - more than twice that of dogs and five times more than human beings.
It is well known that human beings can identify odours through the 350 different types of olfactory receptors
in the nose, which start a signalling process that then messages the brain.
Hanns Hatt at the Ruhr-Universitat Bochum, found that in addition to having 350 different types olfactory receptors
in the nose, human beings the odor receptors in the outermost layer of their skin, keratinocytes, as well.
In contrast, the typical person's nose has 400 olfactory receptors
Our finding indicated that number of antennomers in workers ant antenna (12 antennomers) was more than in male antenna (11 antennomers) this phenomeon was ascribed to the fact that males may use a smaller repertoire of olfactory receptors
for simpler communication needs, also total number of sensilla on ant antenna varied according either to functions of ants (workers or male) and length of the body , since literature pointed out that there is a correlation between size of ant and task assignment .
13) Like Hummel et al, we presume that repeated short-term exposure to odors may result in an increased growth of olfactory receptor
neurons and an increased expression of olfactory receptors
