Cerebrospinal fluid removes toxins, such as amyloid beta protein, which causes Alzheimer's disease. This kind of cleaning can only be carried out after sleeping, which makes people wake up with a fresh brain. When you don't sleep, cerebrospinal fluid doesn't have enough opportunities to enter. In addition, the researchers also found the relationship between EEG activity and cleaning process, that is, EEG guides the movement of liquid. This achievement has just entered the field of science. The author said excitedly: This is a step closer to revealing the relationship between Alzheimer's disease and sleep.
To our complete surprise, someone can really prove that EEG can make liquids flow, just like rowing boats. So, so, sleep more and don't stay up late. If you can't finish brainwashing, you may really become stupid. Why can I brainwash only when I am asleep? When you fall asleep, your brain will go through several different stages: from shallow sleep to unconscious deep sleep, and then to rapid eye movement sleep, which is a state of easy dreaming. This new study focuses on the non-rapid eye movement stage, which is not the time for dreaming, but it is also a very important stage for the brain to maintain memory.
In fact, 20 13 studies have proved that toxins such as amyloid β protein in the brain of rats will be cleared during sleep. Brain cleaner is called cerebrospinal fluid. The question is, how did it get rid of it? Why can I remove it only when I sleep? Scientists conducted an experiment, in which 13 people put on EEG caps and slept on an MRI machine. EEG shows what kind of sleep a person is in. Magnetic resonance imaging measures blood oxygen levels and shows how much cerebrospinal fluid flows in and out. Then we found a wonderful phenomenon: for a long time, the blood oxygen concentration in the brain has changed obviously. In other words, blood will flow out of the brain on a large scale and periodically.
