Magnetic Resonance Imaging - MRI
For a long time, research had no explanation of what happens in the brain during hypnosis. Even today, this is still not fully understood. Since about 10 years it can be observed with a magnetic resonance imaging (MRI), which brain areas are active during hypnosis. MRI studies have shown that the anterior cingulate cortex is activated during hypnosis. This controls our attention. At the same time, the prefrontal cortex, which is responsible for critical thinking and planning, is rather "dampened.
