Floating in zero gravity can put quite the squeeze on the human brain, according to a study published in the New England Journal of Medicine on Wednesday, reports CNN.
Researchers scanned astronauts' brains using magnetic resonance imaging before and after varying lengths of space missions. The MRI scans revealed brain changes in a majority of the astronauts who returned from long-term spaceflight missions.

"There appears to be increased cerebrospinal fluid and an upward shift of the brain within the skull," wrote Rachael Seidler, a professor at the University of Florida's department of applied physiology and kinesiology, in an email. Seidler has participated in similar studies but was not involved with this one.
