Six months in space is not that bad for your brain

Extended time in space is not exactly harmless to the human body. Radiation, altered gravity, sleep loss, can all take their toll on astronauts. Some are even hospitalized upon their return to Earth. Minor mistakes in space can have devastating consequences, so it is important to know how these stresses can impact an astronaut's cognitive performance. A new study published November 20 in the journal Frontiers in Physiology followed 25 astronauts in Low Earth orbit aboard the International Space Station (ISS).
