Who does not hide under the pillow tutorial before the exam in the secret hope that the knowledge of the night will go to the head? In today's world, the ability to quickly learn and remember information is extremely important to achieve success in life, even at the end of the period of study at school or college. Currently, scientists are working to create techniques that allow information to digest in a dream. To do this, researchers are actively studying the processes that occur in the human brain. Recently, a series of experiments that showed how to relate the flow of electric waves and information processing in the brain …

In order to learn in a dream, the human brain uses millions of active neurons, which, like football fans, at the same time lifting his hands and creates a wave, accompanied by shouts of ole-ole, sending a powerful electric pulse which connects the individual cells together. Such brain electrical waves — a phenomenon typical of deep sleep phase. A team of scientists from different countries, according to magazine Spiegel, found that those people who are highly trainable and success in school, particularly characterized by long waves.

According to the author the study Reto Haber (Reto Huber) from the University of Wisconsin-Madison in the state (USA), slow brain waves on the basis of an electrical impulse to perpetuate the memory svezheusvoennoy information. In the experiment, 12 participants were offered computer tests. During the execution of tasks subjects had to click your cursor over a particular purpose. The program works is that while the task is changed independently computer cursor movement and taking part in the experiment, people had their own to compensate for these shortcomings. The results of the study were published in the scientific journal Nature.

Subsequently Haber using magnetic imaging measured the brain activity of participants in the experiment. The results showed that in the section of the brain that is responsible for solving the task of the subjects are of high electrical activity of brain waves. Moreover, those whose results were the best for a night of sleep showed the greatest streams of pulses.

Some researchers who study the nature of sleep, have suggested that nocturnal activity of the brain allows the brain to organize and process the received on the eve of knowledge. For example, the knowledge required or important to be preserved and enhanced, and those that are recognized redundant, will be erased. At present, the hypothesis that learning during sleep may be recognized as valid. In any case, the American scientists in October 2003 reported that during the control experiment the subjects recognize the words that talk vaguely reproduced computer after sleep better than without it. However, scholars have argued that the emergence of techniques allowing to acquire new knowledge in the process of sleep, as well as the consolidation of existing, requires a large number of different kinds of additional research capacity of the human brain.
