<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">Researchers performed MRI brain scans on 11 astronauts before they spent time on the International Space Station. On their return, the astronauts were scanned again and the images of both scans were compared.It was found that areas of the brains of the astronauts had physically expanded in space.</span></span></p>

<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The movement of fluid towards head may be one of the mechanisms causing changes we are observing in the eye and intracranial compartment. Researchers further found that the brain expansion persisted up to a year after the return of the astronauts.</span></span></p>

<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">This is potentially due to dysfunction of water transport in microgravity. Cerebral spinal fluid which is generated in the lateral and third ventricles and which migrates through the white matter accumulates due to this dysfunction.</span></span></p>

<p><span style="font-size:11.0pt"><span style="font-family:"Calibri","sans-serif"">The team is trying to combat the effects of zero gravity to prevent the buildup of cerebrospinal fluid in space to help astronauts safely embark on longer spaceflights to regions that have never been explored before.</span></span></p>
