Scientists discover how hypnosis affects the brain

Researchers from the University of Zurich have discovered that hypnosis changes brain activity and affects the neurochemical environment of certain brain regions.

The work was published in Scientific Reports.

Hypnosis is an altered state of consciousness in which a person can be susceptible to suggestion and changes in perception, memory, and sensations. In this state, a person may be more receptive to suggestions and behavioral changes while remaining conscious and maintaining self-control.

According to recent data, hypnosis affects the brain by changing activity in areas associated with attention and body awareness. This is confirmed by research results using various neuroimaging methods. In one such study, using functional magnetic resonance imaging, scientists identified changes in the activity of the cerebral cortex responsible for the perception of space and time.

During the studies, participants were asked to experience two levels of hypnosis: moderate relaxation and a deeper state called the Esdaile state. In both cases, high concentrations of alpha and theta rhythms were observed, characteristic of a state of deep relaxation accompanied by slowed breathing and heart rate.

Furthermore, the experimental results confirmed that hypnosis is not an imaginary state but represents a real change in brain function. This discovery became an important step in understanding how hypnosis can have therapeutic effects in treating pain, anxiety disorders, and other conditions.

However, scientists emphasize that the obtained results cannot be generalized to all people, and further research is needed for a deeper understanding of hypnosis mechanisms.
