In the brain found "switch" that causes animals and people to sleep so long
Source:In theory, a person can sleep for 2 days simple effects on the brain
In mice, has an interesting ability — when they lack food, they hibernate. While their body temperature is greatly reduced, and the heart begins to beat slower, which together leads to a slow metabolism. Thanks to this dream, rodents can ride out the times when they have no access to food, and Wake up in a better day. Unfortunately, in humans this ability is not, although it would definitely not hurt. In such a dream could leave patients waiting for donor organs, thousands of lives would have been saved. Maybe in a few decades this possibility still appears, because the scientists have found a brain area which is responsible for the transfer of the body in such a dream.
Sleeping animals
Ability to go into hibernation called numbness or corpora. This ability was seen in mice, woodchucks, hedgehogs and many other animals. The state, in which leave these creatures can be compared . However, unlike normal sleep, the stupor leads to a significant decrease in body temperature and slowing of the processes occurring inside the body. Animals do not react to external stimuli and do not feel hunger, so that they can relax in a difficult time.
According to observations of scientists, fall into a deep sleep completely different animal. These include bears, hedgehogs, squirrels, bats and a huge number of insects. From grizzly bears hibernation lasts up to 200 days.
parts of the brain
The Search part of the brain that is responsible for the transfer of animals in a state of torpor, engaged scientists from the U.S. and Japan. According to research , they conducted an experiment in which took part a few mice. With the help of chemicals, the researchers activated these different parts of the brain to record every activity has helped them devices for monitoring the electrical phenomena in organisms. Into the abdominal cavity of rodents has been built-in sensors which caught the change of temperature. The scientists decided that if the activation of a particular brain area of the animal body will be colder — so they found the same "sleep switch".
After several attempts, the desired area of the brain was finally found. They found the hypothalamus, which is very small in size and located in the lower part of the brain. When you activate a group of cells, referred to as the Q-neurons lab mice become less active, the body temperature dropped to 30 degrees Celsius, and breathing became shallow. It became very clear that for the condition of torpor in the animals meet the above Q-neurons.
the location of the hypothalamus in the human brain
After the stimulation of nerve cells, the laboratory mouse has been in hibernation for 48 hours. Two days later they started to come around and eventually started to behave normally. In any case, scientists have checked up, whether there were they during this time, the tissue damage of internal organs — was that all is well. Consequently, all processes which are started by scientists, was a natural, and organisms of the mice were ready for them.
If mice have nothing to eat, they hibernate
the tomorrow People
Now the question remains — is there a brain area in humans? And if there is, can you stimulate and get people to fall into a daze? It may seem that between mice and humans have nothing in common. However, at the molecular level, we have very many similar traits and that is why many medicines and cosmetics are first tested it on laboratory mice.
It is hoped that researchers will not abandon his scientific work and eventually find out for sure whether you can get people to sleep with the help of brain stimulation. This technology would be very useful, because in the future astronauts will have to fly to a distant planet, the way to which takes a very long time. Immersed in a state of torpor, they would be able to save much food and reserve forces to conduct research in a completely different world.
During long space flights, astronauts will sleep. And it's great!
This is a very interesting and useful experiment, isn't it? Such research is very much about one of them I wrote at the end of 2019. Then the scientists of the U.S. state of Virginia taught mice to control tiny cars. More information about this experiment can be read .
