Lack of sleep is a good learning

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.
