Astronaut’s brain is affected by microgravity in space, a study found


communicating results of a study developed with participation of 26 astronauts, about how microgravity can affect the human brain. In other words, the lack of gravity actually changed the physical shape of the astronauts’ brains. The scans also showed that the changes were more dramatic in the astronauts who spent months aboard the as opposed to those who only had brief trips aboard the shuttle. A problem to be answered is now to determine how long the brain changes actually last, and whether trips into space have permanent or extremely long-lasting affects. Changes like muscle degradation can be offset by exercise regimens, but it is not known what it will happen in the brain. The study revealed some big problems that astronauts in long times missions can have.
