{ai:summary}<p>A study of 30 astronauts revealed that extended periods in weightlessness lead to significant changes in brain structure, particularly the expansion of ventricles. Those who spent six months or more in space experienced more pronounced effects, with recovery potentially taking longer than three years.</p><p>The research highlights the impact of microgravity on fluid distribution in the body, resulting in upward shifts that affect brain positioning. While the expansion of ventricles is a normal aging process, the study suggests that prolonged weightlessness accelerates these changes temporarily. #science</p>
