Astronauti se vraćaju na Zemlju sa trajnim promenama na mozgu

Naučnici smatraju da ovo može objasniti zašto neki astronauti imaju problem sa ravnotežom i stabilnošću danima, pa čak i nedeljama posle sletanja

Astronauti se vraćaju na Zemlju sa trajnim promenama na mozgu

TL;DR

  • Space travel causes measurable changes in brain shape and position, even after short durations.
  • These brain shifts can last for at least six months after returning to Earth.
  • Microgravity alters the distribution of bodily fluids, affecting how the brain rests in the skull.
  • Astronauts experienced upward and backward shifts in their brain's position within the skull, with non-uniform changes indicating shape deformation.
  • Changes are most prominent in brain regions responsible for balance, proprioception, and sensorimotor control.
  • The posterior insula, involved in balance processing, showed significant changes linked to poorer post-flight balance.
  • These brain alterations are not linked to personality or cognitive abilities but explain post-flight balance issues.
  • Findings can aid in developing better recovery programs for astronauts on future long-duration missions.
