People have different ideas about how their body moves, scientists have confirmed09/09/2019Russian scientists, together with Spanish colleagues, experimentally confirmed that people mentally imagine the movements of their bodies in different ways. Some have visual imagination, that is, they “see” them, while others have kinesthetic imagination, that is, they imagine the sensations that their muscles experience at work. The data obtained can be used to develop new methods of rehabilitation, for example, for people who have had a stroke. The work was published in Scientific Reports. The research was supported by a grant from the Presidential Research Projects Program of the Russian Science Foundation to support world-class laboratories. Most people use visual images in their imagination, that is, they simply imagine any action as if they are seeing it from the outside. This is visual imagination. But some "trained" people, such as athletes, can imagine the sensations of their muscles. They have kinesthetic imagination. Different images arise as a result of activation of different areas of the brain. When a picture is presented, the areas responsible for the processing of visual information are activated, and when using kinesthetic images, the same zones are activated that are involved in the performance of a real action. Thus, in order to determine the type of imagination in a particular person, you need to understand which part of the brain is actively working during the presentation of movement. Press Service of the Russian Science Foundation using magnetoencephalography. A special installation registers ultra-weak magnetic fields resulting from the electrical activity of the brain. The more intensively the zone works, the stronger the magnetic field emitted by it. Thanks to this, it is possible to understand which parts of the brain were the most active at a particular point in time. The experiment involved 10 volunteers aged 20 to 31 years. In a special room shielded from the Earth's magnetic field, the subject sat in a chair and placed his hands on the armrests. Magnetoencephalograph sensors were placed above his head, which recorded ultra-weak magnetic fields of the brain. When the beep sounded, the subject had to imagine the movement of his hand. The volunteer had a screen in front of him, on which it was reported which limb movement, left or right, should be presented. Press Service of the Russian Science Foundation The data obtained on the functioning of the brain were analyzed in several ways. First, we used the method of transforming mathematical functions, which allows you to trace the smallest changes in the signal over time. In this experiment, the signal was the magnetic activity of the brain. Then artificial intelligence methods were applied. In some cases, scientists did not train a neural network, but simply combined data into groups based on similar parameters of brain activity. In others, an artificial neural network was trained to classify the results of an experiment. The use of three different techniques made it possible to create the most complete picture of the processes occurring in the brain. Thanks to this, scientists were able to accurately divide the subjects into 2 groups according to the types of imagination. The ability to imagine their movements remains even in a person who is paralyzed as a result of an injury to the brain or spinal cord. It is this ability that is used in modern rehabilitation medicine in a special brain-computer interface. An important application of such systems is neurorehabilitation, for example, of patients who have suffered a stroke or suffered a head injury. In this case, movement imagination will speed up the recovery of motor activity, while it is important to pre-classify patients in terms of the type of movements they imagine. The further rehabilitation strategy will depend on this, which will significantly speed up the process of restoring the body's motor functions after brain damage, - commented the project manager, professor at Innopolis University Alexander Khramov. scientists confirmed appeared first on Search - news of science and technology.

10 Multicellular Life Is The Result Of Genetic Mutation
The GK-PID molecule allows cells to divide, avoiding malignant tumors. At the same time, the ancient gene, an analogue of GK-PID, was a builder enzyme necessary to create DNA. Scientists suggested that in some of the ancient unicellular organisms 800 million years ago, the GK gene was duplicated, one of the copies of which then mutated. This gave rise to the GK-PID molecule, which allowed the cells to divide properly. This is how multicellular organisms appeared
