A protein that helps brain development in early stages of life can prevent

"It is interesting that Notch , a protein plays a key role in the development of a people have an important function in the adult brain " .

" We discovered that if Notch activity is enhanced in the brains of fruit flies sleep, they are still conscious and continuous learning. They act as if they had an adequate sleep at night " .

Associate Professor Shaw and his colleagues tested the learning ability of the flies by putting a pair of negative stimuli (quinine, qualities that often flies away) with a positive stimulus (light that flies instinctively seek out).

When you have the opportunity to crawl into a dark pipe or a light pipe containing quinine, the flies can learn to curb the desire to choose their own light.

Like humans, flies a continuous decline in cognitive performance in a way typical day. The prolonged interrupted sleep caused the fly's ability to learn decreases.

Became interested in the protein Notch when his team found a lack of sleep in flies increases gene activity in a protein capable of inhibiting Notch .

They also found a similar situation in people with insomnia. They continue to study and detect when the inhibitor was "waste martial arts" and the activities of the protein Notch is enhanced, the flies can continue to learn both the lack of sleep.

See everything, but not everyone remembers

Those who are not worried about insomnia, can not get lucky with dreams. The result is the same - weakness and fatigue in the morning. In the dream of the day is processed information, which we perceive not only consciously but also unconsciously. In addition, the brain receives signals from the internal organs.

And if the body is some problem, the information is distorted and can affect dreams, make them chaotic. Painful condition interferes with the brain to work on the solution of psychological problems, all in his power to fight for the internal processes.

What determines what you will see a dream? Scientists can not say for sure yet. But suppose that during the night is ordering information, deposit it in the long term or short-term memory. In addition, not having to digest the information for the day, the brain, while you relax, try to solve some psychological problems.

No wonder they say: sleep on it. The next morning many of the problems are removed, because the brain had a night to think about them until the consciousness does not prevent him his instructions.

Sleep fact file

About one-third of our lives are spent sleeping, but very little is really known about it. We sleep in different stages. These range from light sleep, with periods of REM (Rapid Eye Movement) in between, during which we dream. The connection between REM sleep and dreaming was discovered in 1953. It usually begins about 90 minutes after falling asleep and occurs in bursts, totaling about two hours a night, or 20% of your total sleep time. New born babies can sleep for up to 21 hours out of 24. Children and teenagers need approximately 10 hours of sleep a night, while most adults need only 7-9 hours. Those over 65 need the least of all – about six hours. Older people also have deep sleep and less REM sleep than young people. Trains have a “dead man’s handle”, which must be held at all times. If the driver falls asleep and loses his grip, the train stops.
