American scientists have noticed changes in the brains of astronauts in space flights
Experts from the University of Michigan compared the data of magnetic resonance tomography of the human brain before and after space flight. The study included 12 astronauts, each of whom had been in space for two weeks, and 14 astronauts, each of whom had been in space for six months.
As it turned out, the brain is changing, the essence of which — to reduce and increase the thickness of the layer of gray matter in different sites. Changes are more pronounced in those who have been to space more time, but they are visible even those whose flight did not last long.
According to researchers, the changes associated with the redistribution of cerebrospinal fluid in the absence of gravity. At the same time, the increase in gray matter in areas of the brain that control leg movements and machining coming from upside signals associated with adaptation to weightlessness. The researchers compared the corresponding process with continuous, round-the-clock learning a new skill.
It is expected that the results of the study can be useful in developing approaches to the treatment of certain disorders of the brain.
