Scientists have found that fast-wave sleep and slow-wave sleep work differently, and the two states also alternate during sleep. Sleep rests the brain and cerebellum. Animals need to sleep, whereas plants without brains don't; Some organs in the human body, such as the liver, do not rest.
This suggests that sleep is a phenomenon specific to the whole brain, and that at least slow-wave sleep can allow the brain to repair the damage caused by free radicals. Free radicals are by-products of metabolism and can damage the body's cells. Other organs can repair this damage by giving up and replacing damaged cells, but the brain cannot do so, and can only put people into a state of sleep, especially slow-wave sleep, so that human tissues can use this rare "leisure time" to carry out "emergency repair" operations.

There is more than one place in the human body's sleep center, and there are three more important places:
1. The brainstem reticular ascending activation system, which is also the most important system, which is responsible for maintaining the wakefulness of the cerebral cortex. If there is an injury here, the patient will not be able to maintain normal consciousness and will fall into a coma. This system acts under the cerebral cortex to regulate sleep, and if the cerebral cortex issues inhibitory impulses to it, it will cause the person to fall asleep.
Clause. Second, in the hypothalamus, it can not only regulate sleep, but also participate in the body's endocrine system. If the patient's sleep is affected, insomnia and lack of sleep will produce a series of endocrine changes, which will typically cause an increase in appetite and increase the risk of obesity. Clause.
3. Located at the tail end of the brainstem, it is the location of the important respiratory and heartbeat centers of the human body. Part of the sleep regulation center is located in this area, which can increase the wakefulness activity of the cerebral cortex and shorten the sleep time. If it interferes with this area, it can cause the person to fall asleep quickly.

In the human brain, the sebaceous layer is part of the time that controls sleep, the cerebral hemispheres, on either side of the midbrain spine, between the cerebral hemispheres, and the hypothalamus.
The pre-event zone is related to sleep.
-
The brain controls sleep by the sleep center, which is located in the brainstem and hypothalamus, and there is a structure in the brain called the ascending reticular activation system, which will go to sleep if this system is suppressed by the action of the cerebral cortex.

The central nervous system in the brain controls sleep now! Once you are sleepy, the central nervous system will send a signal!

Hello, the process of changing the cerebral cortex from excitability to inhibition during sleep is not controlled by a specific brain location. Suggestion: After the brain is fully rested, it will work better, all positions of the brain need to rest, if it is in a state of excitement for a long time, it is sick.

Judging from the research results of modern brain science, there is no independent localization of functions in the brain, and the realization of various functions is not in one place of the brain, but the result of the interaction of multiple related regions.

Insomnia can keep you awake at night and listless! Many patients are only able to sleep with the help of medication, which is a painful feeling, why does it lead to such serious consequences? Many of them are dependent and unreasonable lifestyle habits caused by long-term medication, which only erupt after years of accumulation.
Some patients fall into anxiety and depression because of some changes in mood, so that it is difficult to fall asleep, and there is no way to quickly enter the sleep state. Once the drug is stopped, it will be difficult to fall asleep, or even sleepless all night, causing the condition to become more and more out of control, so drugs such as sleeping pills must be used with caution.
Number mistakenly believes that the organ that manages sleep is the brain. In fact, the organ that manages sleep is the "sleep center".
Is the sleep center in**?
It's not in the brain, it's in front of the hypothalamus, there's a sleep pacemaker, and there's an wake pacemaker in the back. The hypothalamus unites with the pineal gland to form the "intraneural organ", or the "object clock".
Pineal gland in**?
Between the cerebellum and cerebellum there is the third ventricle and thalamus. Behind the third ventricle there is a small pearly pineal gland. The pineal gland and part of the thalamus together form the sleep pacemaker, i.e., the physical clock system.
Our sleep-wake is managed by this system.

There are sleep control centers in the brainstem, but there are also various things that can affect the quality of sleep.

In fact, most of the human organs are in a state of rest when sleeping, but there are also organs that are constantly moving, such as the brain.
When people sleep, the brain is actually in a state of constant motion, which will be divided into several stages and emit different waves. Let's take a look at the stages.
Stage 1: Waves, waves, the person is awake, the body relaxes, the breathing and heart rate slows, the mind wanders, and the feeling is good (the state achieved by meditation and hypnosis).
Stage 2: The brain gradually tries to shut itself down at this stage, but the person is still awake and theoretically "asleep".
Stage 3 and 4: Deep sleep, the brain alternates back and forth in the state of "waves" and "δ waves", during deep sleep, the breathing heart rate reaches the lowest point of the day, the blood vessels swell, and the blood stored in the organs during the day flows to the muscle tissues, nourishing and repairing them.
Stage 5: Rapid eye movement sleep (REM), also known as dream sleep. At this stage, the frequency of brain waves is high, and it is at this stage that illogical dreams often occur in the morning.
Over time, the deeper the night, the longer the REM sleep and the shorter the deep sleep in each cycle.

Nowadays, there are more and more night owls, and many people go to bed late and have poor sleep quality, resulting in irritability, difficulty in concentrating, and deterioration in physical condition.
Why do people need to sleep.
When a person falls asleep, the brain does not stop working. When a person is asleep, the brain switches between REM sleep and slow-wave sleep. Sleep helps us remember our daytime experiences and consolidate our memories.
REM sleep is very important for emotional memory and procedural memory. Slow-wave sleep, on the other hand, helps us remember our experiences. During sleep, all of our experiences are replayed in the neurons of the hippocampus.
At the same time, sleep helps us effectively clean up the "garbage" in the brain, helping us to work and study better the next day. And keep the brain at its most active. Scientists have found in mouse experiments that sleep cleans the brain of toxins that accumulate during wakefulness, some of which have also been linked to neurodegenerative diseases.
During sleep, the space between brain cells increases, allowing toxic proteins to be excreted to help keep us safe from neurodegenerative diseases.
What the brain is doing during sleep.
Maintain a high level of activity, maintain a series of body functions, and allow people to recover their strength as soon as possible. At the same time, during sleep, cerebrospinal fluid can enter the brain faster, remove toxic proteins from the brain, and remove garbage. The brain will also reorganize all the information obtained during the day, further locking in what it has learned during the day, preventing further loss of information, and thus improving the person's ability to learn when he is awake.
And the brain selects and enhances experiential memories and experiences that are valuable to the individual. During the period of deep sleep, the brain will also rearrange the daily to-do list according to the importance of things, so that people can arrange them smoothly the next day. During the day, people's nerves and muscles are in a very tense state, and only after entering deep sleep, the brain turns off some motor neuron information, and it is relaxed.
What the body is doing during sleep.
In addition to some places to find a comfortable sleeping position, such as rolling over, other movements and behaviors may be performed, and these movements and behaviors are repeated by memory cells.
What are the muscles doing?
Katsushige Suzuki, a Japanese sports nutritionist, has found that growth hormone, which promotes muscle growth, is secreted during sleep. This growth hormone directs amino acids in the blood to muscle tissue, which allows it to create new muscle cells and repair damaged ones. At the same time, adequate sleep can also increase the level of catabolic hormone (a hormone), and the increase in the level of this hormone is also conducive to muscle growth.

Sleep is to ensure that our mental condition can always be good, and the brain is the most diligent organ of our body, when we sleep, the brain will clear waste products along the blood vessels between the brain and spine, and the brain will only be cleaned up when we sleep!

Sleep is to allow the brain and various organs of the body to get a rest and be repaired. Sleep gives the brain and various organs of the body a chance to 'recharge' after a long day's work. During sleep, the brain will integrate and store the day's activities and some knowledge, and will store part of the content in the hippocampus, which will become our long-term memory, and the other part of the content will be put aside, which is what we call forgetting.
So I think sleep is a process for the brain that is just integrating storage. But this process of processing long-term memory only occurs when you fall into deep sleep. So when you rest at night, be sure to let your brain fall into a deep sleep.

Although we sleep for seven or eight hours a day, a person can only sleep effectively for two hours. So, as long as you ensure the quality of sleep, you don't need to sleep that long at all. As long as you close your eyes at noon and really fall asleep for 3 minutes, it is equivalent to sleeping for two hours; Sleeping for 5 minutes at night is equivalent to sleeping for 6 hours.
If you like to stay up late, then make up for sleep at these two times to ensure that you have a full day of energy and no sleepiness!
Or hypnosis on oneself can be equivalent to sleeping for several hours, but judging from the specific method of "sleeping for 5 minutes equals 6 hours", it is actually to emphasize the importance of sleep during the two periods of the meridian. Positive time and noon time are the best periods for sleep, and the quality of sleep is the best, which can achieve twice the result with half the effort. Generally based on the principle of taking a big nap at the time of the child and taking a nap at the middle time, sleeping "at the time of the child" can recuperate and recuperate, and sleeping at the "time of noon" can conform to the development of yang energy.
I hope you think about it carefully, correct your understanding, have a good rest, and hope it can help you.

Usually one hour of sleep is enough.

Sleep and wake up are made up of two systems in the brain, the "wakefulness system" and the "sleep system".
administrative. For those who sleep well, the stronger awake system supervisor during the day, let's keep.
16 hours of sobriety. After that, the power of the awake system decreases, and the weaker sleep system gradually takes over.
Advantage, let's maintain 8 hours of sleep.
Even when asleep, the waking system is still functioning, and it evaluates the one that is happening around it.
cut, such as the ticking of the clock, the temperature in the room, the quilt falling off, etc., and make these scenarios.
React. In addition, the system is more responsive to certain things, depending on what is happening at the moment.
The importance of the relationship depends. For example, the father who can't hear the thunderstorm in the middle of the night will be all will.
The cry of a small baby wakes up at once, and some people don't need an alarm clock to be able at some point.
get up and so on. That is, we are never really cut off from the outside world, ie.
It is time to fall asleep.
Some people seem to be born with a strong sleep system, no matter what's going on outside.
Coaxing, you can sleep "like a pig". On the contrary, some.
The human sleep system is very weak, otherwise the waking system is too strong, so that the sleep problem is more than that.
Others are sensitive. Fathers with more than two children should know that each child is unique.
sleep patterns, such as how long you need to sleep, whether you fall asleep easily, how well you sleep, etc.
Those who suffer from insomnia who have not slept well for a long time are likely to be born with an inherited one.
A less stable sleepy eye system. However, acquired sleep habits and behaviors play a role in long-term insomnia.
Acting in a more important role, so they can still use the techniques of this book to overcome insomnia.
It is the cerebellar region of the brain that innervates movement.
I think of course the brain is the dominant one, the brain controls the heart, the brain drives the nerves of the whole body, and the brain directs the heart, so the heart has good, evil, and beauty. The brain can think and dominate the truth, goodness and beauty in the heart.
The brain includes the telencephalon and diencephalon, and the telencephalon includes the left and right cerebral hemispheres. The telencephalon is the main part of the higher nervous system of the vertebrate brain, composed of the left and right hemispheres, and is the largest part of the brain in humans, and is the high-level nerve center that controls movement, produces sensations and realizes higher brain functions. The telencephalon of vertebrates is a thin-walled bulge at the tip of the neural tube when it is embryonic, and later develops into two hemispheres of the brain, mainly including three parts: cerebral cortex, cerebral medulla and basal nucleus.
In this process, many people feel that breaking their wrists can represent the whole strength, and they also think that fat people will win the championship, and thin people may not be able to win. The fat man actually wrestles all the strength and the whole process, and he may not be able to win the game. The most important thing is, of course, to look at the forearm muscles and the biceps deltoid muscles, which must be combined to win the wrist wrestling final. >>>More
