The sense of smell in a person can be significantly improved through special training - say scientists who conducted a study in rats. According to the findings of experts published in the journal Nature Neuroscience, if a person does not actively use his sense of smell, then over time, it begins to deteriorate, according to the Internet publication for girls and women from 14 to 35 years old Pannochka. Net Similar processes occur in our body during the course of illness and aging, and now scientists have set out to find ways to reverse them, however, according to experts, even given the current level of medical development, it is unlikely. By the way, the state of our sense of smell is an important indicator of the health of the body as a whole, since its loss or significant deterioration occurs in the early stages of Alzheimer's, Parkinson's and schizophrenia.

However, under the influence of which processes the ability of the organism to perceive the smells of the environment is weakening, it remains a mystery. Scientists have organized a rather complex study, during which the rats were forced to recognize certain odors. In the event that the animals correctly performed the task, they received a sip of water. The rats performed the same tasks for a certain period of time, comparing several odor variants and choosing identical. In the second stage of the study, a few more rats were added to the experimental group, which had not previously been subjected to similar procedures. And that's surprising - rats that already had experience of comparing smells showed significantly better smelling rates than newcomers. Thus, according to scientists, this in practice has proved that smell can be improved by training.

Subsequently, researchers connected electrodes to the brain of rats in order to recognize how the odor signals that come to the brain during the execution of tasks change.

Each smell stimulates a certain activity in the pear-shaped cortex of the brain, and the more and more often the rat breathes the same flavors, the more clearly the picture was drawn. That is, in fact, the brain of a rat, accustomed to gradually recognize smells and distinguish them from each other. At the same time, scientists note that the results of such training, obviously, will not last forever, because over time the brain will forget the signals about smells, and without regular training, the sense of smell in experimental animals will soon deteriorate again.
