Can sleep help the brain sort out what it s learned during the day?

The story begins in 1865, when the chemist Auguste Kekuler had a strange dream: he dreamed that a snake was biting its tail to form a ring. Like many organic chemists of the time, Kekuler was studying the structure of benzene.

It was this strange dream that helped him realize that benzene is a ring, and this dream was born out of his years of research on carbon-carbon bonds.

This Kekule-style approach to solving problems may be more or less familiar to many people. That's because when we sleep, our brains are still busy: processing the information we get during the day.

The brain combs through recently formed memories and consolidates, replicates, and integrates information to make it more useful. Sleep keeps memories free from other information and allows for more effective recall. Sleep not only strengthens memory, but also allows the brain to sift through recently formed memories and selectively retain them.

Before the 50s of the 20th century, scientists believed that our brains do not work when we sleep, that is, we forget because new information enters the brain and existing memories are driven out, while there is no information when we sleep so we do not forget much information.

It wasn't until 1953 that scientists Aserinsky and Kleitman published an article stating that the sleep cycle was 90 minutes, and that rapid eye movement (REM) occurred every 90 minutesDuring rem sleep, our brain waves are similar to when we are awake. In the following time, neuroscientists discovered that between the REM phase, that is, the slow-wave sleep phase, a large number of neurons are firing at a rhythm of 1-4 times per second. So the brain is not resting when the person sleeps.

It was in 1994 that our understanding of sleep and memory took a turning point, when a group of subjects were tested on a group of subjects to quickly distinguish objects, and it was found that sleep could make them perform better, and this disappeared when they were deprived of sleep. Subsequent experiments have shown that REM sleep and slow-wave sleep are equally important in this test.

In 2006, another study found that sleep has the ability to consolidate memory. First, they trained the subjects to memorize a pair of words in A-B mode, then put some of the subjects to sleep, after which all learned to memorize pairs of words in A-C mode, and unsurprisingly, the sleeping subjects remembered more groups of words in A-B modeIn the face of the interference of the A-C phrase, the sleeping subjects had a more stable memory of the A-B phrase, which indicates that sleep changed our memory and made it more resistant to interference.

The next study was even more interesting, as they found that sleep is not only good for consolidating memories, but also for filtering memories. Scientists show subjects a set of unpleasant or emotionally neutral **Subjects who tested their memories after sleep found that they had strong memories of emotional** subjects, and that they forgot otherwise.

Yes, sleep does help the brain organize knowledge.

When you sleep, your brain analyzes your newly formed memories to help solve problems and generate new information.

Yes, it can help the brain organize knowledge to a certain extent.

During sleep, the brain organizes, digests, and understands what it has learned.

Yes, that's why we always get an early break.

Sleep helps the brain rest properly.

Yes, it is possible to integrate the newly formed memories.

Think about it before you go to bed and see what you've learned, and you'll sort it out.

Yes, the brain will automatically tidy up at this time.

At this time, the brain automatically organizes the knowledge.

Hello, reviewing before going to bed will strengthen memory, it is very helpful for learning, people are not idle when they sleep, they are still working. "Human sleep is mainly regulated by the transmission of chemicals (neurotransmitters) between brain cells. The same in the state of learning.

Reading a book before bed will have an effect.

Generally speaking, 7-10 hours, each one varies, for example, I need about 9 hours.

In fact, sleep time does not have to be very du

Long means that the quality of sleep is very good! When a person dao

When you feel sleepy, you can take a nap to give your brain a full rest! For example, taking a nap during the lunch break every day will form a habit and you will be very energetic when you go to work!

Sleeping too long or too short can cause neurasthenia. Proper sleep is the key to maintaining vigorous energy.

Sleep for 7-8 hours.

8 hours But it's best to wake up naturally.
