Scientists have identified the effect of norepinephrine on memory during sleep

Scientists have announced that the stress hormone norepinephrine (norepinephrine) causes the brain to wake up more than 100 times during a night’s sleep.

And the journal Nature Neuroscience notes that, according to scientists from the University of Copenhagen, these short periods of wakefulness do not harm the brain, but rather improve memory.

The researchers say: “Technically, a person wakes up because the activity of the brain in this short period is similar to its activity during the waking period. However, the sleeping person does not notice this.

To study the mechanism of sleep, the researchers conducted experiments on laboratory mice, and it became clear to them that their results also apply to mammals, as the experiments proved that short waves caused by norepinephrine “reboot” the brain, allowing it to save and update information. information he received earlier.
