The tired brain is capable to disconnect partially neurons

From St. Anna's Higher school in Pisa (Italy) and University of Wisconsin-Madison was possible to prove (USA) to researchers experimentally that the brain is capable to "disconnect" some zones to allow to them … to sleep, — transfers ScienceNews.

As it is known, earlier scientific assumed that the brain falls asleep completely as soon as will receive a signal from one centre. Experiments on rats have proved that at strong overfatigue and a sleep debt separate neurons  are capable to "fall asleep" at own discretion.

To estimate activity change neurons  rats, it in different sites of a cerebral cortex implanted to 20 electrodes. After that an animal prolonged the wakefulness period at four o'clock much. As a result in one of experiments it was found out that, despite external vivacity, 2 from 20 investigated neurons  were disconnected.
When an animal with "fallen asleep" neurons  suggested to pass "obstacle course" to get a delicacy, that, at outwardly normal activity, at them was observed coordination infringement. For comparison, at the slept rats complete control over muscles was observed.
Therefore, if you have suddenly found out that have forgotten keys which have put in a prominent place, or have missed by a sugar bowl, that, probably, it is necessary for you to sleep properly, and for this purpose only and it is necessary that a convenient bed, attress pad and good linen. The freshness and an aesthetics of the last as scientists are assured, too are very important for a high-grade dream.
