Путешествие на Марс может быть опасным для мозга, - NASAJourney to the red planet can harm the hippocampus.

Studies have shown that during this time, part of the hippocampus (a region that takes part in the formation of memories) of the participants declined on average by 3%. According to scientists, this could be a result of social isolation and stress from the fact that the participants of the experiment were under surveillance 24 hours a day. It is also noted that volunteers were engaged in physical exercises six days a week, so it is unlikely that the reduction of the hippocampus was the result of low activity.

However, what was the reason for such changes, researchers don’t know. Furthermore, it is unclear the impact of such reductions on the person. Scientists emphasize that these changes are reversible thanks to brain plasticity, but they must be taken into account when training astronauts.

The publication notes that a survey of 2026 adult residents of the UK, which was held Sapio Research in August, showed that a journey to Mars would take 50% men and 30% women. If we are talking about the flight one storeno, such a step would have agreed 30% of men and 20% women.
