While in space, the brain “floats” in space.
American scientists from the University of health and of human activity in Florida has announced the opening of a new negative factor for the human presence beyond Earth, according to the Chronicle.info with reference to Esoreiter.
Professor Rachael Seidler and her colleagues scanned the brain of several zvezdoleta before and after space flight. It turned out that being in zero gravity changes the white matter in the areas responsible for controlling movement and processing sensory information.
According to the researchers, this degradation of the brain resembles the one that occurs in humans with aging, but in orbit it flows far faster. This may explain why many astronauts, upon returning to Earth suddenly have problems with coordination and balance retention. It is curious that the shorter the mission of zvezdoleta, the more pronounced disorders of the brain. Apparently, the Central nervous system is able to adapt to weightlessness after some time spent in orbit. However, the health consequences are still not the best.
The study involved 15 astronaut, returned to Earth. It turned out that after flying at the base of the brain going to the cerebrospinal fluid. The brain of each of these people actually sailed in the skull above the ordinary.
And, despite the fact that the balance of the white matter, usually resolve a few weeks after the astronauts return to our planet, the consequent changes in the brain can persist much longer and may even become irreversible.
