What happens to the brain when it's in a weightless state? – Space – Science

When space travel is still in the baby's dream, scientists have tried to solve how to get the earth's gravitational force and launch a rocket in outer space. Although Gravity is still one of the most important issues in science today, researchers are now struggling to prevent the negative effect of microgravity on human health and especially on the brain. This is because a person has evolved into an environment with 1 g of gravitation. In the distribution there is 0G, but Mars – 0.3g

How does humanity affect microrevity? In short, it's bad. True, the information about it is quite limited. It is surprising that it is known to everyone that the astronaut face remains red and swollen in the unbalanced position. This phenomenon is referred to as the "Charlie Brown Effect" or "Swollen Head and Bird Siftrom". This is because in a weightless state all body fluids flow in the direction of the head, put their head on the head, but the legs become thin.

Body fluids are also associated with nausea and headache, as well as blurring from the eye, which is due to increased blood pressure in the brain, which they arise in the inside of the skull. The NASA sees the syndrome as the greatest threat to astronauts of the Mars mission, but it is still unclear how this can be prevented.

Professor Damian Bailey, in a Time-Powered Time, finds that some parts of the brain get too much blood due to gravity, because nitric oxide (an invisible molecules in the blood) that converts into the circulatory system leads to an enlargement of the Arteries and the so-called cerebral blood barrier overload, which are the brain to accumulate in water and increase stress. This syndrome may intensify the vision of the astronauts and adversely affect their cognitive and engine capabilities.

Journey in the Wowl Comet

To test this idea, an experiment is needed, in which eight volunteers, for four consecutive days, experienced a 30-second, simulated weightlessness at the "Woven Comet" aircraft. No-intelligence, researchers measured blood pressure in various arteries that bring blood to the brain, levels of nitric oxide in the blood, and brain is observed.

The results of the experiment demonstrated the initial hypothesis that the level of nitric oxide in the unweight increased in the blood, which resulted in an increase in blood flow to the brain, resulting in overloading the brain blood barrier. True, brain damage is not observed.

It is now planned to complement the research with more detailed information in order to validate all the proposed theories and begin to work on finding solutions.
