They form a functional complex with another protein, the so -
called olfactory receptor co-receptor, which enables insects to smell the tiniest amounts of odor molecules in their environment very rapidly.
In 2004 the Nobel Prize in Physiology or Medicine went to Linda B. Buck and Richard Axel for their research showing that there is a huge family of genes that encode proteins
called olfactory receptors.
Not exact matches
Physicist Marshall Stoneham and his colleagues at University College London report they have constructed a specific mechanism based on the properties of so -
called G - protein coupled
receptors, which project from
olfactory cells inside the nose.
The neurons send their signals to the brain's
olfactory bulb, where each of thousands of little clusters of neurons
called glomeruli receives input from
olfactory neurons with just one
receptor type.
McRae and colleagues found that the genetic variants associated all lie in or near genes that encode so -
called odorant or
olfactory receptors.
Kenyon cells make up only about 4 % of the entire fly brain and are extremely sensitive to inputs triggered by odors, in which only two connections between neurons,
called synapses, separate them from the
receptor cells at the «front end» of the
olfactory system.
You can think of dogs as having two noses — the 300 million
olfactory receptors and their Jacobson's organ — and this Synaptic Smelling System (my phrase, trademark pending) allows trained dogs to detect odors
called volatile organic compounds.
