BKSin (International Space Station) came to this conclusion after observing the health of 12 astronauts that, stay weightless for a long time nerve cells and to the white matter of the brain has a negative effect. Scientists believe that, These changes are due to the need for the body to adapt to weightlessness. As a result, changes occur in the structure of communication between nerve cells. Previous studies have already confirmed this that, long stay in space lumbar muscles weakens and has a negative effect on the heart. Mars possible long-distance flight to the planet space radiation to brain cells reduce the intellectual abilities of astronauts due to the impact and can lead to mental problems. Specialists to observe changes in the brains of astronauts magnetic resonance imaging used.

A few days before the astronauts flew to the BKS, immediately after returning to Earth and They were observed seven months after returning to Earth. The data obtained from the observations were processed by special algorithms that analyze the relationship between different parts of the white matter of the brain. Specialists have relied on the nature of the motion of molecules inside cells. So scientists have learned that, Prolonged stay in space, in turn, changed the connections of the parts of the brain responsible for motor skills. Seven months after returning to Earth, these changes have been preserved. Scientists believe that, Such changes may have occurred as a result of the random distribution of white matter in the brain due to prolonged stay in space. Scientists are currently working on strategies to restore the normal functioning of the brain.
