Astronaut brain fluid “redistributes” in zero gravity

  On October 20th, according to foreign media reports, scientists conducted in-depth research on 11 astronauts who arrived at the International Space Station and found that the liquid around the brain of the astronauts redistributed in the skull during space flight.
  The research was led by Steven Ullings, a doctoral student at the Balance Research and Aerospace Laboratory (LEIA) of the University of Antwerp, Belgium, and confirmed previous findings about the effects of microgravity on the human brain. Ullings and the research team studied the brain conditions of 11 astronauts before spaceflight, nine days after landing, and six to seven months after their return to Earth. The latest research shows that astronauts who have been on a six-month mission on the International Space Station often feel their heads move upwards, and under microgravity, the fluid around the brain and spine will redistribute.
  He said in an interview with reporters: “Cerebrospinal fluid is the fluid that surrounds the brain and spinal cord. These fluids have multiple functions, but it also helps to buffer space when you hit your head. So people’s brains Tissues will not be easily harmed.”
  In addition to buffering brain collisions, CSF also helps to remove “waste” from the brain. In this latest study, they monitored the body of astronauts and found that CSF will be in the brain after the astronauts return to Earth The lower part gathers, which indicates that their brains are moving upward in space as a whole. However, this is only a temporary phenomenon and is reversible. In the follow-up monitoring scan, they found that the brain almost completely recovered to the state before the space flight.
