Most people think that sleep is not enough, and for some people, there is half of ordinary people sleep. Dolphins sometimes only sleeps with half a brain. The mouse will die if you don't sleep in 3 weeks, and the male emperor can not sleep in a whole 3 months of hatchery. Sleep is a ubiquitous phenomenon in the animal industry - or even insects also sleep. We have 1/3 of the time in his life to sleep. Non-people know why we need to sleep, how to happen to sleep. We have become a very embarrassing thing for sleep lack of understanding. But our ignorance is not because we have no effort to study. There are dozens of statements for sleeping. These statements can be divided into four categories: rest and restoration, avoiding predator, storage energy, and information processing. Many researchers are more happy to admit that there are many roles in sleep, which may be correct. But they have no confirmation or negation. Sleeping problem is difficult to crack why sleep is a problem with such a difficult solution? A great barrier is its double nature. When we sleep, it is switched between two different states. The first kind is slow wave sleep, and features a slow-fluvous activity that occurs in the entire brain. The other is a fast eye activity sleep (REM), which is characterized by a brain activity, which is almost the same as the unsained EEG. Its exterior performance is also very obvious: the eye is fast, the muscles are in a few near paralyzed states (it is believed to prevent you from making a move). Rem appears in the early stages of evolution ---- reptiles, birds and mammals have such sleep state. It is also a very active and exciting state. Therefore, its role should be large. Anything about sleeping is not to ignore its existence. In fact, explaining that REM has always been the center of sleep research. Although a large number of researchers are still busy studying REM and Dream, some new theories about sleep function in recent years have pushing REM in the background, and believes that non-REM status is real sleep. These theories believe that REM is just a non-REM state auxiliary. Can these new ideas eventually crack this problem? New theoretical new exploration These theories have one of the sleep researchers of Stanford University Craig Herle. 6 years ago, he found that the radio wave activity in the non-REM sleep state has some abnormalities. When she carefully observed my ecommap, he saw some short and subtle activities, as if it was converted to the REM state but did not succeed. He found that these phenomena occur more and more frequently until the brain finally transferred to the REM state. That is to say, the pressure that enters the REM state appears to gather in a non-REM sleep state until the brain can no longer suppress it. Heler said it is likely to be a breakthrough discovery. Most of the theory about sleep state control assumes that there is an external switch to switch the brain in sleep from one state according to a predetermined schedule (typically 90 minutes). Both sleep conditions have enough time to play their own roles. However, the conversion that is unsuccessful to the REM state indicates that this change is controlled by additional mechanisms. It seems that it seems that the need for non-REM status generates entering the REM status ---- It is like a clear state in the finals. Further confirming that this theory is the fact that the time in a REM state is proportional to the previous non-REM state, the longer you are in a non-REM state, the more REM status may be required to recover ". According to this view, the REM state is reduced to a secondary position, just as the restoration phase after the brain works in a non-REM state. At the same time, there are still some views that do not completely push the secondary position in the back of the REM state.
Turkis, the computer neural biology laboratory of the Solk Institute, California, proposed a hypothesis that non-REM status also has a recovery and trimming role, which is related to the cravy activities of the awake state. " Constructive Project "---- Supplement Protein, enhanced protruding, embedding the susceptor into the cell membrane. In the process, you must be unconscious, so there will be no neurological activity to hinder it ---- just like construction workers working in the house, you need to move. When the brain completed some construction work, it did a temporary report to the REM state. In fact, the brain activates certain awake systems in a limited environment to test the results of work, see what else needs to do. Then it switch back to the non-REM status and continues to complete the construction work. These "non-REM rules" theories are in that they help explain why the brain will pass several non-REM status and REM status in the sleep, and why sleep always starts from a non-REM state. If both sleep states have their own independent features, they cannot explain how they are alternate. However, if the non-REM status determines the role of the REM state, then the Switching of the sleep state is much more meaningful. Other views of theoretists are, sleep is more than just a process of resting and recovery. They believe that sleep ---- especially REM status ---- plays an important role in brain processing information, classification and storage, even creative thinking. It is at least traceable to 1983 in the viewpoint of learning and memory in learning and memory. At that time, one of the discoveresses of DNA double helix structure James Watson proposed that the REM status was responsible for removing unwanted information and experience. Since then, this field study has been continuously developed, and many evidence shows that the REM status and "program memory" (learning how to complete complex tasks such as cycling, playing piano) are closely related. However, since the measurement found that the effect of non-REM state is getting bigger, the REM state has a less smaller, and the researchers have begun to play a major role in the information processing process. This is a big reversal. Trent University Sleep Laboratory, "Strengthening Memory" Association of Advocors of Sleep Theory: "Previous REM status has been considered important, and now slow wave sleep is constantly being improved." Especially Yes, the brain handles space memory when it is in slow wave sleep -, for example, a unfamiliar city recognizes. One experiment requires volunteers to recognize the direction in a virtual city with a steering wheel, while using positively transmitted computer tomography technology to imaging their brain. The results of the fault scan showed the active hippocampus regional activities in the brain. According to the previous experiment, it plays a key role in spatial knowledge learning. The subject then falls asleep, but the brain is still connected to the positively transmitted computer tomography. In slow wave sleep, the brain activities displayed in their hippocampus are the same as the brain activities in the study state, and their recognition capacity in the next morning has improved. Philip, Perie, who was conducted by this test, said: "Slow wave sleep is related to memory." The views learned in the sleep process are very attractive, and it is easier to accept the public. But not everyone think it is correct. There is such a small part of a strong opposition to think that sleep and memory have no relationship. It seems that before there is more evidence, even the most attractive sleep function theory can only be "unconfirmed" inference. Sleep exploration continues to improve, starting from modern sleep research to now, half a century has passed, is there any progress in interpreting sleep? To date, our understanding is progressing.
