GAINESVILLE, Fla. (University of Florida PR) — Brain scans of astronauts before and after spaceflight show changes to their white matter in areas that control movement and process sensory information, a University of Florida study shows.
The deterioration was the same type you’d expect to see with aging, but happened over a much shorter period of time. The findings could help explain why some astronauts have balance and coordination problems after returning to Earth, said Rachael Seidler, a professor with UF’s College of Health and Human Performance.
