Hypnose hat laut der Universität Zürich messbare Effekte im Gehirn
Original
Scientifically speaking, hypnosis is still largely a black box, wrote the University of Zurich (UZH) in a press release on Tuesday. However, studies by researchers at UZH now show that hypnosis actually changes something in the brain.
To demonstrate this, the neuroscientists at the UZH conducted studies using various imaging techniques. Each time, they selected 50 healthy people as test subjects. They were first put into a light state of hypnosis and then into a very deep state of hypnosis using the same spoken text.

AI-powered neurotechnologies raise hopes and fears for health and privacy in Geneva

Neurotechnologies integrating artificial intelligence (AI) can treat diseases such as Parkinson’s but they can also alter the brain and read the mind.
The studies found hypnosis leads to changes in certain areas of the brain that are important for attention and body perception. According to UZH, the corresponding areas were less active or their ability to connect was reduced. This could therefore mean that hypnosis reduced the subjects’ awareness of the body. At the same time, theta waves were increased, which are a sign of sleepiness and deep relaxation.
The researchers also observed significant neurochemical changes. A neurochemical modulator called myo-inositol was released significantly more during deep hypnosis. According to the researchers, this could be interpreted as reduced brain activity.
According to the researchers, further studies are needed to understand how hypnosis works.
