Canadian scientists from the University of Western Ontario invited volunteers from around the world to participate in the largest study of the human brain to find out how lack of sleep affects its work.. This is reported by the Russian service of the Air Force.

“Everyone is familiar with the sensations that arise when there is a lack of sleep, but we know little about how such a lack affects the brain,” explains the scientific task of the head of the study, British neuroscientist professor Adrian Owen..

Scientists have to figure out how the brains of different groups of people work, depending on whether they get enough sleep or not.. Volunteers are invited to take a series of tests online to assess their logical thinking, linguistic skills and ability to make the right decisions.. The researchers believe that if they manage to recruit enough volunteers, they will be able to develop recommendations for the amount of sleep that ensures the most efficient brain function, according to Pannochka, an online publication for girls and women from 14 to 35 years old.. net Tests offered to volunteers are available on any device with an internet connection. For example, during one of them you need to click on the word below, corresponding to the color in which the word above is written. If the word at the top is " Everything seems simple, but the gray matter should work.

Another test becomes more difficult as the volunteer tries to find a pattern that does not match the features of the general series.. And the spatial planning test measures information processing skills that are used in everyday life..

These trials were offered to one group of volunteers who had to stay awake on university premises until 4 a.m., followed by four hours of sleep.. The results of most of them in the morning were significantly worse than the night before..

The brains of the subjects were scanned, and it turned out that after a sleepless night, its activity was noticeably reduced - much fewer processes were observed on the shooting.. What is the risk?

“It is possible that lack of sleep can significantly affect decision making.. It might be worth avoiding major decisions like buying a house or getting married without getting enough sleep, says Prof Owen..

It is well known that you should not drive a car without getting enough sleep, because the reaction is inhibited, and in general you can fall asleep at the wheel. However, much less is known about the subtle, but no less insidious consequences of everyday sleep deprivation.. Therefore, scientists are alarmed that modern people have less and less time to sleep.. It turns out that the development of civilization went against the laws of nature, according to which a person should spend a third of his life in a dream..
