Imagine you could throw the perfect bullseye, but you'd have to wear glasses to do it. That's a trade-off some space travelers may unwittingly make when they venture off the planet.
A study published Friday examined the brains of eight male Russian space travelers nearly seven months after they returned to the International Space Station from a long mission.
The researchers suggested that men were more likely to wander but had a slightly weaker view of the space travelers' brain discovering minor changes.
The lead author of the study, s." he said, "he has actually acquired some kind of new motor skills, like riding a motorcycle, like the business insider, Steven Gillings.
Researchers used a variety of MR to create 3D images of space travelers' brains.
An increasing amount of tissue involved in the scan has increased: part of the brain responsible for balance, co-operation, and currency (shown in the green in the video below).
But the scan also shows that people living in space can be with the near-sighted misery they see. Both these changes may be long-term.
Change in motor skills after space travel
Any human brain, whether it has been on the spot or not, can adopt new environments and experiences. For example, many players have acquired specific motor skills directly related to their sport.
..if you study MRI, where you compare ordinary people with athletes or people who actually use motor skills like dart players, for example, you have to work to modify the hepotes.
On average, russian space travelers spent six months on the space station in this study. Researchers expected space travelers to see temporary changes in the brain, but they were surprised to discover that the improved motor skills were still several months after they were back on Earth.
Brain changes, possibly resulting in blurred vision
Several previous studies have revealed that the microscopic stoics face physiological changes, including muscle and bone damage.
Space and space travelers exercise more than two hours a day to deal with this process in general. They may also feel dysentery or motion-sick while their bodies are adjusted to the vegetalisis environment.
One important difference between space and life in earth is that our blood and body fluids usually move against the bottom of gravity, while in space, the space men's physical fluids move up.
New studies show that microgravity causes the brain to move simultaneously. This results in the distribution of liquids in which the brain floats.
Jesus said his studies show that water can pile behind the eye, causing swelling. It can drag near the space, resulting in a condition called the neuron ocular syndrome attached to the space flight.
A 2012 survey showed that many NASA spacecraft found the same effect among 60 who were studying that they were less clearly looking at the spacecraft. NASA also changes the perspective of a space traveler only if the space-based glass of the prescription fly.
But Jesus said there is still much to learn about this phenomenon, especially because not all astronauts or space travelers return to Earth with a bad view, and most astronauts have only studied being a victim of vision in one eye. Restore their view soon after anything returned to Earth.
What's more, many Russian space travelers have a very sharp look to start with, even after they completed an identity in place, their approach is still more common than the average person.
The fact that we see small gaps probably means that all these people have some common effects that spend six months in space.
Scientists are still trying to determine its degree in which vision can be permanent.
An April study from the University of Texas shows that the swelling in the stoic stoics' brain persists one year after their return to earth. But Jesus said that there is no research to follow long-term how long the condition really stays out of it.
Overall, Including The Jillings, it is good news that their study did not raise any serious health effects associated with space travel.
In contrast, by previous studies, radiation in space can lead to neurulation, which can accelerate the development of Alzheimer's disease among the neurons.
