It’s good news for anyone planning on spending months floating around in the International Space Station (ISS) or for those who might one day find themselves on a long-haul flight to Mars, as researchers imaging the brains of Russian cosmonauts have found that while the brain does undergo changes in a microgravity environment, it doesn’t deteriorate.
New research suggests prolonged exposure to microgravity does cause parts of the brain to reorganise itself, but does not trigger loss of brain tissue.
