Researchers from across the US compared a series of MRI scans of 15 astronaut brains taken prior to a six-month stay on the International Space Station, and up to six months after their return
Using algorithms to carefully assess the sizes of perivascular spaces the team found time spent in orbit had a profound effect on the brain's plumbing. For the first-timers, at least
Among the pool of veteran astronauts there appeared to be little difference in the sizes of perivascular spaces in the two scans taken prior to the mission and the four taken after
