What's with hypnosis? Scientists have studied this phenomenon 150 years, but they have never been able to figure out its true meaning. Some theorists believe that hypnosis opens the door to the subconscious, some people tend to think that trance is a psychological marginal state of not sleeping and waking, and some people simply call it pseudoscience. But there is no doubt that people are most likely to accept hints under hypnosis, which can make them do some even the most violent actions, because at that time, the brain and even the body began to help themselves. Whether hypnosis is true or not, some experts who study the marginal state of perception have solved some unknown mysteries through similar experiments.

When people are hypnotized, they will secrete more anesthetics.

Professor Gyanendez and Professor Rosenthal of Harvard Medical Center also found another incredible attribute of hypnosis: patients are in a trance, and fractures and surgical wounds can heal faster.

The first study invited 12 patients with ankle fractures to participate. Gé né ndez hypnotized six of them once a week for three months, and the other six only received general treatment. Another group of experts observed the patient's bone healing through X-ray fluoroscopy. They don't know who is hypnotized and who is not. The results show that hypnotized people leave two weeks earlier than those who receive general treatment.

Some biochemists think that this is the result of the influence of endorphins, and Razygrayev agrees with this view. Endorphin is an anesthetic synthesized in human body. It is said that patients will secrete more under hypnosis, thus alleviating the pain during the healing process. Because it can bring pleasure to people, there is a feeling of anodyne.

However, how to explain another experiment conducted by the United States not long ago? There, the success rate of artificial insemination for women under anesthesia is twice as high, which seems to be more than just an endorphin problem. But at present, hypnosis is not effective in treating mental illness, heart disease and infectious diseases.

Under hypnosis, human blood circulation will be improved.

Not only to explore the mystery of hypnosis, scientists have been trying to use hypnosis to treat diseases. The Swiss university of basel issued a statement saying that they have found a new method to treat pollen allergy, which is very effective. Their method is hypnosis.

The study was conducted for two years, and 66 patients with pollen allergy volunteered to be tested. In the first year, they were divided into two groups. The first group did not actually participate in the experiment in the first year, and continued to take those traditional anti-allergic drugs as usual. The second group, under the guidance of experienced neuropsychologists, hypnotized themselves for the purpose of getting rid of the main symptoms of * * *, while continuing to take general antiallergic drugs, but the dose was small. The effect of the first year is very obvious, but the seasonal symptoms of the second group of patients in bloom are not so obvious, and they are no longer frequent runny noses. In the second year, the people in the first group were hypnotized, and at the end of the "allergy season", they also admitted that their symptoms had eased.

Scientists believe that the symptoms of these people have been alleviated because the blood circulation of the human body has been improved under hypnosis, which has solved or partially solved the problem of love in the respiratory system.

However, although people who accepted the experiment said that similar methods were effective in treating allergies, they still lacked factual basis, which was only their self-feeling, not medical appraisal. And at the same time of hypnosis, you still have to take a small dose of anti-allergic drugs. Even some researchers who participated in this experiment admitted that they only proposed a method that could even help treat pollen allergy, and did not think that they had found a new treatment.

New research seeks scientific basis for hypnotic effect

After a series of exploratory experiments, scientists began to turn their research to rationality. Whether hypnosis is related to brain reaction has become the focus of their attention.

Scientists once asked people to hold bricks with both hands when doing experiments. The longer the better. People can only hold it for 5 minutes under normal circumstances, but even women can hold it for half an hour under hypnosis. Tomography shows that if the two hemispheres of the brain work at the same time under normal circumstances, only the right hemisphere responsible for emotion and artistic creativity is active in a trance state, which seems to "suppress" any attempt by the left hemisphere responsible for logic and intelligence, making people know that they are holding it foolishly.

Another new study proves that hypnosis can effectively avoid cognitive conflicts by changing the activities in specific areas of the brain.

The researchers used a classic method, asking subjects to tell the ink color of their handwriting. Faced with the word "green" written in blue ink, subjects often hesitate and make mistakes when answering "blue". If the same subjects look at the word again after hypnosis, they will regard the word as a meaningless symbol.

Reitz, a cognitive neuroscientist at Columbia University in new york, and his colleagues focused on the brain activity behind this result. In the initial behavioral research, the researchers found that those who were highly hypnotized judged more accurately when faced with the conflict between word meaning and color than those who were slightly influenced by hints.

Related brain imaging also shows that the affected brain areas include the area responsible for early visual processing and the anterior cingulate cortex, which is known to be related to people's attention, emotional control and self-regulation. The researchers reported their findings in the online edition of Proceedings of the National Academy of Sciences.

"The surprising thing about this explanation is that reading is regarded as an unconscious process," Ritz said. However, the fact is that a special hint subverts this process by changing the activity of the brain. He believes that this means that hypnosis can be used to activate and close specific brain regions.
