Fixed memory is boosted when you sleep while shaking

by Oleksandr Pidvalnyi

It is shown in two new papers published in the journal Current Biology for biology that not only improves the quality of sleep but also boosts the fixation of memory when experiencing the movement of "shaking" during sleep it was done. Two research findings done on humans and mice are a new approach to treatment of insomnia.

The first research published in Current Biology is an experiment conducted on humans. Mr. Laurence Bayer, a biologist at the University of Geneva in Switzerland who studied, defines "good sleep" in this case as "falling asleep and experiencing a deep sleep all night" about.


Like Mr. Bayer, Sophie Schwartz of the University of Geneva conducted an experiment to monitor sleep at laboratories for 18 healthy young people to ascertain the effect of "sleeping while shaking". On the first night we asked the subjects to sleep without doing anything to get them used to the experiment, one night in the next two nights "in a gently swaying bed" and the same bed for the other night " "There was no shake" and I had you sleep.

As a result, the subjects showed that they fell asleep more quickly when the bed was shaking, and once they got to sleep, there was no eye movement and the time of non-REM sleep increased, leading to a deeper sleep.

Next, the researchers investigated how useful a good sleep is in fixing memory. In order to investigate how long memory fixation is done, subjects had a pair of words remembered. The pair of words I remembered in the evening of the previous day were adjusted as to how accurately the subject remembered in the morning of the next day and it was shown that the memory was fixed when there was a shake during sleep It is said that it was done.

In addition, researchers discovered that the shaking and sleeping creates brain waves indicating non-REM sleep. From these data, the researchers see that shaking sleep synchronizes the neural activity of the thalamic and cortical network, which plays an important role in sleep and memory fixation.

In another study conducted by Konstantinos Kompotis of the University of Zurich and others, experiments were conducted on mice about the shaking during sleep. Researchers rocked the cage during sleeping of the mouse, the optimal vibration for the mouse was four times faster than that of humans, but even in the mouse, the time until the shaking falls asleep is shortened and the sleeping time is lengthened It was indicated that it was shown. However, evidence that the mouse was sleeping deeper is not shown.

Researchers who considered "rhythmic stimulation to the vestibular system that is responsible for the balance of the body in the relationship between sleep and tremors are involved" also investigated mice in which otoliths do not function. As a result, it is said that mice in which otoliths do not function are not affected by shaking during sleep.

Mr. Bayer and Mr. Perrault said the two studies "show new findings on neurophysiological mechanisms underlying the fact that the sleeping shaking is effective." These studies will be a new approach to insomnia, mood disorders, and sleeplessness and memory loss experienced by elderly people. For that purpose, the researchers show that it is essential to investigate to understand the structure of the brain more accurately.
