Scientists have described how the sense of smell can affect a person’s life.
Scientists have discovered a link between the sense of smell in humans and the burgeoning network of social networks. It turns out that a good sense of smell can make a person successful without any other data.
Human social networks consist of people with whom he has regular contact. In the new study, researchers found that people with a good sense of smell has contacts with a large number of people. To confirm this theory, researchers examined people on smell: sensitivity to subtle flavors, the ability to distinguish between different odors and the ability to recognize aroma. Also people were tested, they were asked how many friends, colleagues, family members, and how often for two weeks a person goes with them on contact.
The more sensitive to fragrances were people, the greater grew his social network. But there was no connection between vosprinimaetsya flavors and the total number of all friends, even those with whom subjects not communicate.
Through MRI scanning scientists have confirmed that some areas of the brain in people with a good sense of smell is closely in contact. One of these regions is the amygdala, responsible for emotion and social behavior. The other area is the orbitofrontal cortex, is thicker in people sensitive to fragrances.
In comparison with many mammals, people have a weak sense of smell and some of the smells we are not able to perceive. But, having sensed the smell of another person we still are able to determine the sex, age and compatibility of the person with you. The scientists also noted that the smell may come and information about the moral state of man, sadness, joy or even disgust. All this we can understand, but people with autism or schizophrenia often do not have similar olfactory abilities. And totally devoid of a social identify people with anosmia, the deviation in which there are no human scent. It turns out that people with impaired sense of smell at least protected in social terms and many things are not clear even at the physiological level.
At the conclusion of the study, the researchers fed a resolution that is not too surprising that the scent is directly related to sociability: “the Participants with higher olfactory sensitivity may be more sensitive to the smell other people’s body and can get more social chemical signals that help social communication”.
