The experiment was conducted on rodents. Scientists gave the rodents snotvornoe and put them to bed in various poses. Using MRI during sleep were installed lymphatic pathways by which the various wastes are discharged from the brain that accumulate during wakefulness.
In the experiment it was found out that during sleep the brain is actively cleared, which explains the human need for daily sleep, the scientists concluded. In addition, it has been proven that sleeping on your side is the most useful to man. During the experiment, the rodents that slept in it on the side, showed high brain activity and the most effective cleaning function.
According to scientists, after the purification of waste the brain starts to work more productively.
