Mattew walker, a researcher at the National Academy of Sciences and professor of neuroscience and psychology at the University of California, Berkeley, found that sleep quality will determine whether a child gets good grades or fails in the exam – a full 40% gap.
Over the past 10 years, research has found that people need to sleep after learning to preserve those new memories so that they won’t forget what they have learned.
Recently, Mattew Walker further found that before learning, people also need sleep to prepare the brain – just like a sponge. After it has dried out, it can be ready to absorb new information. If there is no sleep, the memory plate of people’s brain is like full of water and can’t absorb new information.
Mattew Walker’s research team specifically tested the effect of “staying up all night”.
The team found a group of people and divided them into two experimental groups: normal sleep group and sleep deprivation group.
People in the normal sleep group will sleep for 8 hours; People in the sleep deprivation group will stay in the laboratory and remain awake under complete supervision, without nap or coffee.
The next day, the research team put the participants into an MRI scanner and asked them to learn a series of new knowledge.
At the same time, the researchers will record snapshots of participants’ brain activity and then test their learning effect.
The test found that without sleep, the brain’s ability to produce new memories decreased significantly by 40%. It can be seen that the problem of insufficient sleep is perplexing the school-age population to a great extent.
To this end, the research team explored the causes of these learning disabilities in the brain.
On the left and right sides of the brain, there is a structure called “hippocampus”, which can be imagined as an information receiver of the brain. It is very good at receiving new files and saving them.
The hippocampus, located between the thalamus and the medial temporal lobe, is a part of the limbic system and is mainly responsible for the storage, conversion and orientation of long-term memory.
When you look at the hippocampus of people who sleep all night, you can see a lot of sound signals of learning activity. However, in those who do not get enough sleep, almost no obvious signal can be seen. In other words, lack of sleep will turn off people’s memory receiver and any new files will be ejected; New content can’t be written into memory.
Therefore, if people are deprived of sleep, they may encounter the above situation.
