Sleep after learning enhances memory

    




Research aimed at understanding mechanisms of memory are one of the priority directions of modern medicine. It turned out that there are factors that can impair a person's memory, for example, hypertension. However, there are natural mechanisms that memory can be strengthened. And the easiest and most pleasant of them is a dream.

Experts of the international group of scientists from Beijing and new York research universities results of a scientific experiment proved that sleep consolidates new information in the brain of any living creature.

According to experts, if you sleep every time the human brain gets some new material, problems with memory will be less.

To be placed by the online edition of Science, scientists reveal the mechanisms of interaction of this type of holiday and fastening in the memory the new material. The secret is in the special mechanism of a miniature of dendritic "spines", which are specific membrane growths. These formations are responsible for creating between neurons new connections (synapses).

Scientists explain that the process of the emergence of this type of links is the fundamental basis of every process of remembering. The dream perfectly enhances growth activity of dendritic growths in the prefrontal brain region.

So there is a fresh consolidation of material into memory. And experts managed in the course of his academic work to consider in detail the mechanisms of the influence of sleep on the formation of long term memory.

Experiment conducted on genetically modified mice, have clearly shown how sleep affects the formation of fresh connections between neural processes of the brain. However, according to the author of the project Wen-WNA Gan, the same mechanisms work in the case of man.

Laboratory animals were taught to balance on a stick, the rotation of which happened every time with the new speed. Once dendritic "spikes" marked the beginning of growth, rodents were divided in two groups. Animals of the first group slept for seven hours each time, as soon as the next stage in learning. In the second group of required sleep was not.

Analysis of the state of the brain of rodents showed that in animals of the "group of sleep" dendritic growths and neural connections were an order of magnitude greater than in the group of mice that were deprived of sleep after mandatory training.
In practice, this means that the animals who were allowed to sleep after each stage of the learning process, were able to remember a much greater amount of new material.

It was also found that depending on the type of session, the experimental mice triggered the growth of the different branches of the neuron. This fact clearly shows the need for various information that the individual can develop versatile.
