Smell and smells

Man and animals, along with other senses of the surrounding world, have this important function. One of the experimental polls: "Which sense organ would you give up in the first place, if the need arose?" The majority answered: "Smell"... Why: what - there are more bad smells than good ones? Or vision and hearing, for example, are more important for a person?
A part of the brain called the olfactory bulb is responsible for the sense of smell in humans and animals (see photo 1). So, in fish, for example, with a fantastic sense of smell, this bulb, compared to the brain itself, is simply huge. And with a person - the opposite.
According to a certain circle of scientists, in a person who is able to process olfactory information not only with the help of the bulb, but also with the brain - and only with him - this is why the brain developed in such a way that the pre-human (due to the prevailing circumstances) began to walk straight, his upper limbs turning into hands. F. Engels argued that it was hands and manual labor that made a man out of a monkey. But maybe, in reality, the human brain became human from the fact that he assumed an additional function - the function of smell? And people neglect this sense organ so much ... This is such ingratitude!

Whatever scientists have suggested and asserted, the world of smells is an interesting and fascinating world! Let's admire him with the "eyes" of the animal world. For him, the sense of smell and smells, as you now understand, are much more significant and important.

Here are some prime examples:

Dogs have 230 million olfactory cells in their noses, while humans have only 10-11 million - twenty times less. However, a dog cannot find something that does not smell at all.

Animals cannot distinguish and react only one smell that a person needs. This happens, in part, because the olfactory cells completely change over the course of a month. Their special services have to constantly "train" on the desired type of smells. If dogs could only distinguish one odor, it would be possible to release, for example, odorous dollars, which would remove the problem of foreign exchange smuggling.

Now let's talk about favorite scents. What are your favorite scents? Most people love the smells of fresh bread, freshly cut grass and coffee the most. The smells of rolls and coffee not only whet the appetite, but also increase the desire to buy. Therefore, supermarkets often smell of coffee and fresh pastries.

Many animals also have favorite scents: dogs, for example, have the smell of anise, cats have valerian and mint, and lions love good perfumes. Camels are attracted by the smell of tobacco smoke: that's why there are cigarettes with the name "Camel".

People living "in the dungeons" of a noisy civilization do not feel almost 70% of the city's smells. But, an African aborigine living in the wild can catch the scent of a friend who walked along a forest path a few hours ago.

And, of course, about the perfume: the French databank contains more than 8000 names in its catalog. Modern perfumes can be made up of 300 different ingredients. Over 6,000 types of various raw materials are used to create perfumes.

1. According to a study published in the journal Science in 2014, a person's nose can perceive at least 1 trillion distinct odors.
2. Some of the most pleasant smells people consider the aroma of vanilla, some smells of citrus, cinnamon, cookies and ... crayons. The author of this study is Dolores Malaspina, professor of clinical psychiatry at Columbia University in New York.
3. According to Professor Malaspina, the sense of smell is the most ancient sense. Even unicellular organisms have ways of perceiving the chemical composition of the environment.
4. There are a number of anomalies in the sense of smell. Among them are anosmia (complete or partial loss of smell perception), dysosmia (impaired sense of smell, when instead of one smell another is perceived), hyperosmia (excessive perception of smell).
5. A group of scientists from Tel Aviv University are developing a new way to identify a person - using the smell of his sweat. According to their theory, sweat is a person's chemical fingerprints that are unique to everyone.
6. The sense of smell is responsible for 75–95% of the perception of taste. Without inhaling the smell of a product, we perceive its taste much worse and cannot distinguish one type of food from another only by its texture.
7. Loss of smell may indicate the development of Alzheimer's disease. A decrease in the ability to perceive odors is associated with a loss of brain cell functionality.
8. Perception of smell can be one of the ways to diagnose autism. According to some studies, children with autism do not distinguish between pleasant and unpleasant odors and inhale them in the same way, without trying to inhale a deeper "tasty" aroma or breathe shallowly if the smell is bad. During experiments, this "breath test" showed 81 percent accuracy in making a diagnosis in children aged 7 years.
9. The nose determines the sound of the voice. What we hear when people speak or sing depends a lot on resonating structures in the throat and nose. The sound itself is produced by the vocal cords, but its richness is determined by how it is "processed" above the cords.

However, This is one of the most complex plastic surgery procedures in terms of functionality. Indeed, sometimes we are talking about millimeters that separate a successful operation from an unsuccessful one.

For the screening of the 1960 film "The Smell of Mystery", a Smell-O-Vision system was installed in several American cinemas to accompany the events on the screen with smells. A tube was connected to each spectator place, and the smells were blown out of the tubes centrally throughout the hall, and the system worked without the participation of an operator at predetermined time intervals. However, the first screenings caused a lot of negative responses: some viewers complained about a strong hiss during the presentation of smells, others about the fact that the smells were several seconds late in relation to the action on the screen. These problems were later resolved, but rumors of poor equipment performance, coupled with negative reviews about the film itself, had already scattered, and Smell-O-Vision was never used again.
