For a long time many scientists thought hypnosis is a little-known trick. After recent studies, the results of which indicate, that under the influence of hypnosis in the human brain there are certain changes, opinion about hypnosis has changed. As noted by David Spiegel, Doctor of the Department of Psychiatry School of Medicine, Stanford University (Stanford University School of Medicine), the United States, during hypnosis, some parts of the brain are relaxed, while others are beginning to function more actively. D. Spiegel believes his latest research can demonstrate the importance of hypnosis as a neurobiological phenomenon. Such a discovery is also able to attract the additional attention of the scientific community to study hypnosis.
Hypnosis is a form of psychotherapy, which is in the western part of the world long ago doctors used in various studies. It is worth noting that by the end do not understand the mechanism of action of hypnotic trance on human consciousness. Hoping to learn about hypnosis more D. Spiegel, together with his colleagues organised a study where participants were 57 healthy volunteers. Of these, 36 had a high level of susceptibility to hypnosis, while the rest (21 persons) were not very susceptible to it. All healthy volunteers were examined using magnetic resonance imaging - the method by which the investigating organs and tissue, using nuclear magnetic resonance phenomenon. Brain Scan party took place in three states: at the time of rest, while the memory of something that at the time of exposure to a hypnotic trance.
As a result, scientists have found that in healthy volunteers with high susceptibility to hypnosis during a hypnotic trance there were changes in the brain. At the same time, these changes disappeared after the man out of the trance. It should also be noted that in healthy volunteers with a low susceptibility to hypnosis revealed no changes in the brain during a hypnotic session.
So what are the changes in the brain occur in some participants during hypnosis? Firstly, the reduced activity of the anterior cingulate cortex. Cingulate is a part of the limbic lobe, which is operably linked to memory processes, attention, emotional manifestations, obtaining new knowledge. Secondly, an increasing number of connections between the prefrontal lobes and insula cortex. Insula helps a person to link the body and mind, and the prefrontal cortex is responsible for the planning and execution of tasks. Finally, reducing the number of connections between the dorslateralnoy part of the prefrontal cortex, and that part which is becoming more active in the times when a person is dreaming.
The researchers note that people under hypnosis are more focused, but at the same time is not very worried about what they do. They clearly follow the instructions, but they do not care assessment of their actions. The team hopes that the results of the study will help physicians in the treatment of various diseases. The researchers' work was published in the «Cerebral Cortex» magazine.
