Researchers from the University of Michigan in the USA have found that the brain of astronauts changes during spaceflight. It is the first to look into how the brain changes on the into space. Researchers looked at of the brains of 26 astronauts who spent time in space. The photos were taken by -tech medical called MRIs. Twelve of the astronauts spent two weeks as Space Shuttle members, and 14 spent six months on the International Space Station. All of them experienced increases and in the size of different parts of the brain. The researchers said that the an astronaut spent in space, the bigger the differences in were.
The research produced some findings. The researchers explained that, " is not available to pull down in the body". This means there is a in the position of the brain inside the . The brain becomes either more squashed or bigger in size. The could help doctors in the future to treat problems that affect the brain's . One possibility is to treat people who develop problems caused by long-term bed . Another possibility is to treat those who have a build-up of in the brain, which can lead to brain damage. The researchers also say we will understand more about how in the brain make connections. In addition, the findings will help future space travelers on their journey to Mars.
