Additional 3-4 hours of sleep a day for only two days restored memories in fruit flies with a condition similar to Alzheimer's disease. This is reported by American scientists from the University of Washington School of Medicine in St. Louis.
The results of this discovery are important for a person, as the neural mechanisms that control sleep in fruit flies are similar to those that control sleep in humans.
Employees of the University of Washington conducted a scientific experiment with two-winged insects - fruit flies, the brain that regulates sleep cycles in the same way as the human brain.
The insects were divided into three groups, in each specialty "Switch off" the gene responsible for memory. In the first group there were deviations, symptoms that resemble Alzheimer's disease. In the second group there were problems in the formation ofmemories and the third group suffered from an overabundance of memories.
To find out the effect of sleep on the brain and, in particular, memory, Scientists have increased the duration of sleep for several hours. Such a move would restore the ability to form new memories in all the experimental insects despite the problems with the genes. According to scientists, extra hours of sleep activate cell communication that encode important memories and reduce the number of connections, responsible for unimportant information.
It should be noted that scientists have repeatedly proven that lack of sleep impairs the health and adversely affects the immune system, resulting in premature aging, obesity, diabetes, hypertension and depression. At the same time naps lasting only half an hour can reduce the level of stress in the body and enhance immunity.
Earlier, Swiss scientists have found that green tea extract also has a beneficial effect on the human brain and can improve working memory.
