Just one sleepless night leads to a malfunction of the brain

Just one sleepless night can make the brain unstable, causing a sudden gap, during which attention is turned off and the possibility of visual perception, according to publication Daily Mail.

Dr. David Dindzhes and his colleagues at the University of Pennsylvania conducted a study and found that sleep-deprived brains spontaneously switches from wakefulness to sudden periods of impaired attention.

This is a phenomenon scientists have been compared with a voltage drop in the electrical circuit. The cause of failures in the human brain, deprived of sleep are instantaneous stopping of blood flow in certain areas of the brain, recorded by professionals MRI scanner.

The experiment was carried out brain scans from 24 people. The subjects were asked to perform simple tasks requiring high visual attention, first in the day when they get adequate sleep, and then - after a sleepless night.

Watching people, Dr. Dindzhes concluded that not enough sleep and wakefulness change the periods of inattention occur very quickly. "Imagine you're sitting in a room and watch a movie with the lights on. When the brain is stable, the light stays on all the time. But in the" sleepy "brain, the lights suddenly turned off
