With close to 300 million olfactory receptors at the end of your pup's snout, he can smell up to 100,000 times more than you, so the Wooly puts your furkid's nose and brain to work by mimicking a hunt for food in grass or fields.

Not exact matches

Dogs have more types of olfactory receptor than we do — but as Mainland points out, cows have more than dogs (about 1,200 compared with 800) and it's not clear that cows are significantly better at smelling.

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.

«At the beginning of the experiment we did not expect that the olfactory receptors would have completely different effects.»

«The fact that the MS4As have been preserved for at least 400 million years suggests that these receptors play a crucial role in enabling animals to interact with the olfactory environment,» Datta says.

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.

At least we haven't lost the olfactory receptors that respond to the scent of roses.

As all three studied insect species emerged at different times in insect evolution, the scientists wanted to track the historical development of olfactory receptors.

The work contributes to a growing appreciation of the molecular diversity of olfactory and pheromone receptors, says Catherine Dulac, a neuroscientist at Harvard University.

Vomeronasal receptor (A) and olfactory receptor genes (B) annotated as functional (black) are expressed at significantly higher levels than those annotated as nonfunctional pseudogenes (grey).

Alternatively, they could be expressed at a different age [23], or they may be cryptic pseudogenes that have disrupted promoter elements and thus are no longer recognized by the machinery regulating olfactory receptor choice.

The octopus genome contains around 1,800 C2H2 zinc finger transcription factors, the second largest gene family so far discovered in animals (olfactory receptor genes in elephants are the largest at around 2,000).

At around 1,800 genes, it is the second - largest gene family to be discovered in an animal, after the elephant's 2,000 olfactory - receptor genes.

While the front part of a dog's nose is almost entirely committed to respiration, the rest is committed to olfaction — the sense of smell — and since there are hundreds of millions more olfactory receptors in a dog's nose compared to a human's nose, a dog is able to smell more and detect a scent in much smaller quantities: «This means two things: A dog definitely experiences smells, odors — volatile molecules — that we don't,» Alexandra Horowitz, assistant professor at Barnard College and author of Inside of a Dog, told Modern Farmer.
