What happens to the brain in weightlessness?

For anybody not a secret that NASA took on an impossible task: to send humans to Mars by 2030. Why? Because it is enough to understand that a typical trip would take from three to six months, and the crew will have to stay on the planet up to two years before the alignment of the planets will allow him to return home. This means that astronauts have to live in conditions of reduced (micro) gravity for three years at least — this greatly exceeds the current record for continuous stay in space, the Russian cosmonaut Valeriy Polyakov: 438 days.

In the early days of space travel, scientists worked hard to figure out how to overcome the force of gravity so that the rocket could like from a catapult to launch into space and to land people on the moon. Today gravity also remains on the agenda of science, but this time we are more interested in how reduced gravity affects the health of astronauts, especially their brains. In the end, we evolved to exist in earth’s gravity (1 g), but not in the weightlessness of space (0 g) or microgravity to Mars (0.3 g).

“Brain in a VAT”

So how does the brain cope with the microgravity environment? In short, very bad — however, information is limited. We know that astronauts face redden and swell in weightlessness is a phenomenon affectionately called “effect Charlie brown”. This happens mostly because the fluid, consisting mainly of the blood (cells and plasma) and cerebrospinal fluid shifting to the head, causing the face to become puffy and rounded, and his legs are thin.

These fluid shifts are also associated with “disease space” (similar to sea), headaches and nausea. Recently they were also associated with blurred vision because of pressure rise while increasing blood flow; the brain floats in the upper part of the skull, exerting pressure on him. Despite the fact that NASA believes the impairment and displacement of the brain the main risk to the health of any person on Mars, find out what causes it and how to prevent it, has not yet happened.

Professor of physiology and biochemistry Damien Bailey of the University of South Wales believes that certain parts of the brain end up with too much blood, because the blood accumulates nitric oxide is an invisible molecule that is usually there. The arteries that supply blood to the brain, relax, therefore, revealed stronger. As a result of this rise in blood flow blood brain barrier “shock” the brain becomes overloaded. Water slowly accumulates, the brain swells, pressure increases.

Imagine if the river overflows its banks. The most important thing in all this is that in some parts of the brain not getting enough oxygen. This is a big problem, which may explain the blurred vision and other effects that manifest themselves on the abilities of the astronauts to think, concentrate, reason and move.

A trip on the “vomit comet”

To test the idea, scientists must implement it in practice. But instead of asking NASA trip to the moon, they just decided to break free from the shackles of earth’s gravity, modeled weightlessness on a special plane called “the vomit comet”, the “vomit comet”.

Lifting into the air and then descending, the aircraft to carry up to 30 parabolic shapes per flight to simulate the feeling of weightlessness. The free fall lasts only 30 seconds, but the face manages to swell and in those half a minute.

Safely securing all equipment, the scientists measured among the eight volunteers, each of which made one trip each day for four days. They measured blood flow in different arteries, supporting brain, using a portable Doppler ultrasound makes high frequency sound waves bounce off circulating red blood cells. Also measured the level of nitric oxide in blood samples taken from veins of the forearm, as well as other molecules, including free radicals and specific brain proteins (which reflect structural brain damage) — they could tell whether you open the blood brain barrier by force.

Initial findings have confirmed exactly what was expected. The levels of nitrogen oxides increased after repeated “attacks” of weightlessness, and this coincided with the increase in blood flow, especially in arteries supplying the back part of the brain. The blood-brain barrier was opened, although no evidence of structural brain damage was not.

Now scientists plan to continue these studies with more detailed assessments of changes in blood and fluid in the brain using imaging techniques like magnetic resonance to confirm the results. They also want to consider the possibility of introducing countermeasures such as rubber pants, which create a negative pressure in the lower part of the body and help “pump” blood out of the brain of the astronaut — as well as drugs counteracting the increase nitric oxide. The results of such works can not only improve the health of astronauts in space travel, but also provide valuable information on why “gravity” is useful for the brain.

  1. Hey, how’s it going?

    I want to pass along some very important news that everyone needs to hear!

    In December of 2017, Donald Trump made history by recognizing Jerusalem as the capital of Israel Why is this big news? Because by this the Jewish people of Israel are now able to press forward in bringing about the Third Temple prophesied in the Bible

    Jewish Rabbis have publicly announced that their Messiah will be revealed in the coming years who will be a leader and spiritual guide to all nations, gathering all igions under the worship of one God

    Biblical prophecy tells us that this Jewish Messiah who will take the stage will be the antichrist who opposes and exalts himself above all that is called God or that is worshiped, so that he sits as God in the temple of God, showing himself that he is God (2 Thessalonians 2:4) For a time he will bring about a false peace, but Therefore when you see the ‘abomination of desolation,’ spoken of by Daniel the prophet, standing in the holy place (Matthew 24:15) then there will be great tribulation, such as has not been since the beginning of the world until this time, no, nor ever shall be (Matthew 24:21)

    More importantly, the power that runs the world wants to put a RFID microchip in our body making us total slaves to them This chip matches perfectly with the Mark of the Beast in the Bible, more specifically in Revelation 13:16-18:

    He causes all, both small and great, rich and poor, free and slave, to receive a mark on their right hand or on their foreheads, and that no one may buy or sell except one who has the mark or the name of the beast, or the number of his name

    Here is wisdom Let him who has understanding calculate the number of the beast, for it is the number of a man: His number is 666

    Referring to the last days, this could only be speaking of a cashless society, which we have yet to see, but are heading towards Otherwise, we could still buy or sell without the mark amongst others if physical money was still currency This Mark couldn’t be spiritual because the word references two different physical locations If it was spiritual it would just say in the forehead RFID microchip implant technology will be the future of a one world cashless society containing digital currency It will be implanted in the right-hand or the forehead, and we cannot buy or sell without it Revelation 13:11-18 tells us that a false prophet will arise on the world scene doing miracles before men, deceiving them to receive this Mark Do not be deceived! We must grow strong in Jesus AT ALL COSTS, DO NOT TAKE IT!

    Then a third angel followed them, saying with a loud voice, “If anyone worships the beast and his image, and receives his mark on his forehead or on his hand, he himself shall also drink of the wine of the wrath of God, which is poured out full strength into the cup of His indignation He shall be tormented with fire and brimstone in the presence of the holy angels and in the presence of the Lamb And the smoke of their torment ascends forever and ever; and they have no rest day or night, who worship the beast and his image, and whoever receives the mark of his name” (Revelation 14:9-11)

    People have been saying the end is coming for many years, but we needed two key things One, the Third Temple, and two, the technology for a cashless society to fulfill the prophecy of the Mark of the Beast

    We all know God exists Why? Because without Him, we couldn’t prove anything at all Do we live our lives as if we cannot know anything? No So why is God necessary? In order to know anything for certain, you would have to know everything, or have revelation from somebody who does Who is capable of knowing everything? God So to know anything, you would have to be God, or know God

    A worldview without God cannot account for the uniformity and intelligibility of nature And why is it that we can even reason that God is the best explanation for this if there is no God? We are given reason to know or reject God, but never to know that He does not exist

    It has been calculated by Roger Penrose that the odds of the initial conditions for the big bang to produce the universe that we see to be a number so big, that we could put a zero on every particle in the universe, and even that would not be enough to use every zero What are the odds that God created the universe?

That the Bible makes 10 times more creation claims than all major holy books combined with no contradictions, while these other books have errors in them?

    Jesus came to pay a debt that we could not; to be our legal justifier to reconcile us back to a Holy God; only if we are willing to receive Him: For the wages of sin is death (Romans 6:23)

    God so loved the world that He gave us His only begotten son, so that whoever believes in Him, through faith, shall not perish, but have everlasting life Jesus says if we wish to enter into life to keep the commands! The two greatest commands are to love God with all your heart, soul, strength, and mind; and your neighbor as yourself All the law hang on these commands We must be born of and lead by the Holy Spirit, to be called children of God, to inherit the kingdom If we are willing to humble ourselves in prayer to Jesus, to confess and forsake our sins, He is willing to give the Holy Spirit to those who keep asking of Him; giving us a new heart, leading us into all truth!

    Jesus came to free us from the bondage of sin The everlasting fire was prepared for the devil and his angels due to disobedience to God’s law If we do the same, what makes us any different than the devil? Jesus says unless we repent, we shall perish For sin is the transgression of the law We must walk in the Spirit so we may not fulfill the lusts of the flesh, being hatred, fornication, drunkenness and the like Whoever practices such things will not inherit the kingdom (Galatians 5:16-26) If we sin, we may come before Jesus to ask for forgiveness (1 John 2:1-2) Evil thoughts are not sins, but rather temptations It is not until these thoughts conceive and give birth by our own desires that they become sin (James 1:12-15) When we sin, we become in the likeness of the devil’s image, for he who sins is of the devil (1 John 3:8); but if we obey Jesus, in the image of God For without holiness, we shall not see the Lord (Hebrews 12:14)

    The oldest igion in the world is holiness through faith (James 1:27) What igion did Adam and Eve follow before the fall? Jesus, Who became the last Adam, what igion does He follow? Is He not holy? He never told us to follow the rituals and traditions of man but to take up our cross and follow Him (Luke 9:23) There are many false doctrines being taught leading people astray This is why we need the Holy Spirit for discernment Unlike igion, holiness cannot be created It is given to us from above by the baptism of the Spirit Jesus is more than a igion; He is about having a personal ationship with the Father Start by reading the Gospel of Matthew, to hear the words of God, to know His character and commandments Follow and obey Jesus, for He is the way, the truth, and the life!
