Scans reveal how brain adapts to life in space

Analysis of brain scans finds increase in white and grey matter in regions involved in physical movement

Brain scans of cosmonauts have revealed the first clear evidence of how the organ adapts to the weird and often sickness-inducing challenge of moving around in space.

Analysis of scans taken from 11 cosmonauts, who spent about six months each in orbit, found increases in white and grey matter in three brain regions that are intimately involved in physical movement.
