MRI scans before and after space missions revealed that astronauts' brains compress and expand during spaceflight, according to a US-based study. The study was based on 12 astronauts who spent two weeks in a spacecraft and 14 who spent six months on the International Space Station. Researchers observed that the gray matter volume increased in regions that control leg movement.
