MOSCOW (Reuters) – Russian scientists at the Institute of Biomedical Problems of the Russian Academy of Sciences have discovered that long-distance flights could cause serious changes in the psyche of astronauts caused by radiation. cosmic.
The scientists' experiments on rats consisted of leaving one group under the conditions of the Earth and a second set in the Nuclotron unit of the Institute of High Energy Physics, thus creating conditions similar to those that would meet astronauts on Mars. These rats were exposed to a radiation dose such as that recorded by the Kyorocyte probe on the red planet.
Experiments have shown that radiation has not really affected the brain of rats, but their psychology has been altered, with abnormal changes in their behavior, such as excessive anxiety, hyperactivity, movements and avoidance of open spaces.
Based on these modifications, the researchers concluded that changes in the serotonin cycle in the body of these rats.
"The study of molecular changes in the work of radiation-related neurons will help understand how to protect Martian astronauts and prevent changes in their psyches and other negative consequences," the researchers explain.
