“Beasts of Science” is like a collection of short stories. Beautiful stories told by the living in all their freshness. But also in all its complexity. A parenthesis to marvel at the world’s treasures. For this new episode, once again, let’s go back to what has become our best friend: the dog.
When you smell the droppings, it’s a bit annoying. We have to admit it. But when it comes to inhaling different drugs and their effects

And it has been known for a long time, the dog has a function of smell
The sense of smell relies on chemoreceptors in the nose that detect volatile chemicals in the air.

When you look closer, it’s not very surprising. the

In comparison, ours, always on the nose, does not count more than 5 million!

Located in the braincase, the brain is the seat of higher functions (cognitive functions, senses, nerve responses) and vegetative functions. It is therefore an essential organ that regulates everything…” data-image=”https://cdn.futura-sciences.com/buildsv6/images/midioriginal/5/c/b/5cb474dd85_121782_cerveau-3d .jpg” data- url=”https://news.google.com/health/definitions/biology-brain-3125/” data-more=”Read more”> same conclusion. The dog’s olfactory bulb, that is, the region of the brain that processes the messages sent by scent sensors, is up to 30 times larger than that of humans. With approximately 40 times more cells dedicated to odor analysis.
And all that without mentioning the amazing organ that thecalled the vomeronasal organ. It is placed on the upper palate of the dog. Connected to the nose by two small canals. Thanks to it, the dog can analyze odors with incredible delicacy. Even when the so-called single covalent bond…” data-image=”https://cdn.futura-sciences.com/buildsv6/images/midioriginal/d/0/e/d0e3dc7e1e_76472_molecule.jpg” data-url= ” https ://news.google.com/sciences/definitions/chemistry-molecule-783/” data-more=”Read more”> fragrant are not legion.
Smell and sight are connected to each other
The extraordinary power of the dog might already seem to hold no more secrets to scientists. But that would be forgetting his boundless curiosity. Because despite everything, they were baffled by a dog whose

researchers in #CornellVet have provided the first documentation that dogs’ sense of smell is integrated with their vision + other unique parts of the brain, revealing how dogs experience + navigate the world. Dr. Pip Johnson is the lead author of the study. https://t.co/FWoyKr6mlq

Twenty dogs participated in the experiment. All dogs are very good sniffers, let’s face it. And what the researchers have observed are, firstly, connections between the olfactory bulb, which is located behind the

The occipital lobe is the region of the brain that processes… visual information! Yes, you read it right. In dogs, smell and sight are connected by the brain. Some scientists guessed so. But this time, it’s proven. This also explains how dogs that have gone blind manage to orient themselves so well in their surroundings. Much better than us. Good news for humans who share the life of a dog. And one more sign that ournot so stupid!
