Space Travel Scientists’ brains shrunk in Antarctica Scientific news, scientific news, scientists’ brains A new study shows that the brains of 9 researchers have shrunk after 14 months in an exploration station in Antarctica.
A group of researchers who spent 14 months in Antarctica returned with smaller brains, according to a new study, according to the Daily Mail.

Eight scientists and a chef were staying at a research station off the coast of the icy continent. But looking at an empty landscape for a long time, living in a small structure with the same people for more than a year has put pressure on their brains.

MRI scans before and after the voyage showed that parts of their brains that are Space Travel involved in learning, emotion and memory became smaller during the voyage.

Meanwhile, the people who lived in the house did not experience any reduction in parts of the brain during the same period of time, and in fact, some parts of their brains had grown.

These findings are similar to scientists ‘discoveries about the effect of living in space on astronauts’ brains. Research has shown that astronauts’ brain capacity decreases after space travel, and changes in their brain’s electrical activity occur.

Various German universities and the University of Pennsylvania in the United States have conducted this research. The study shows that if different parts of the brain are not used, they will be destroyed.

Because the researchers

Because the researchers’ brains were not sufficiently stimulated during the voyage, parts of it Space Travel became weaker and smaller.

The same thing happens in the muscles of the human body.

“Watching a white desert may seem exciting at first, but it repeats itself over time,” said Alexander Provin, lead author of the study.

The researchers found that a part of the brain of Antarctic researchers called dentate gyrus, which processes and stores sensory information, was 10 percent smaller than average. Other parts of the brain, including the learning part, are reduced by about 5 percent.

As a result of this trend, the emotional intelligence of polar researchers may have diminished and their ability to communicate with each other was weakened. The researchers lived in Antarctica at Neumayer Station III. This station is located on a snow-covered ground.

Astronauts go to war against neurological diseases

Scientists are simulating the human brain on the International Space Station to identify and treat some of the deadliest neurological diseases.
According to the Club of Young Journalists, scientists have announced that they intend to grow a species of human brain cell on the International Space Station. The goal of scientists in culturing and growing human brain cells in the microgravity state is to study some neurological diseases and find treatments for them.

Researchers say that research into neurological diseases and their treatment can take years or even decades, and one of the reasons human brain cells are being simulated is to refrain from testing on living human brain cells, which is immoral.

In this study, scientists sent brain organoids to the International Space Station to study the effect of microgravity on them. According to scientists, the state of microgravity can affect the basic function of brain cells, including the formation of neural cell networks.

The human brain uses many neural networks or interconnected neural cells to transmit and process information received from the five human senses.

Brain organoids are small masses of brain cells that form functional neural networks and Space Travel divide into three-dimensional structures.

Scientists have recently begun using brain organoids in a wide range of research on the function of brain cells in space. Read more: Selected International Space Station images of Earth beauties

Organoids are very small white structures that can mimic the early stages of human brain cell growth and are a model for studying biological processes involved in neurological diseases and age-related diseases such as Alzheimer’s and dementia.

According to researchers, living in a microgravity state in space increases and accelerates the aging process and ultimately causes changes in the human body.

One of the changes that occur in the human body during life in space is the hardening of the walls of the arteries.

According to researchers, for example, people with Alzheimer’s disease last for decades, and usually in the age of 60 to 70 years, the symptoms of the disease appear in the body.

Scientific news, scientific news, neurological diseases
Using organoids in space requires the same amount of time, so scientists are looking for ways to reduce this time to study the effect of disease on brain cells over a shorter period of time in space.

The organoid model depicts only part of the brain cells but can also mimic and mimic other brain tissues. They are a tool for accessing the developmental stage of brain cells.

Organoids were first sent to the International Space Station in July this year. They lived for a month at that time and quickly began to multiply and grow into different types of cells. After about a month, the organoids were returned to Earth for further experiments.

Another thing that scientists intend to achieve by researching organoids is to study how to protect human health during long space travel.

Scientists want to find out whether organoids survive and thrive during long space travel, or if their lifespan is shortened.

The study of how organoids behave in microgravity space is important for long-distance space travel and will lead to new discoveries about the human brain.

Astronauts are exposed to various dangers when traveling deep in space. Like Hollywood sci-fi movies, these explorers can be threatened by threats such as space aliens, insane computers, and collisions with meteorites or space debris. But the greatest danger an astronaut can face is the unseen danger called space radiation.
The Earth’s atmosphere and magnetic field protect living things on the planet from cosmic Space Travel rays, according to Fiz. As astronauts emerge from this protective bubble, tiny, highly energetic particles called cosmic rays bombard their bodies. The most worrying effect of these particles on astronauts’ bodies is damage to their brains. According to experiments performed on mice, the radiation disrupts brain activity and impairs learning, memory, and mood.

damage to your brain

Space travel can cause serious, permanent damage to your brain

At present, due to the available technology, it is not possible to protect astronauts from space radiation. There has been a lot of research funded by NASA on astronauts, and there is evidence of brain damage from space radiation. These findings raise scientists’ understanding of the dangers and allow them to think of ways to deal with them.
