Hypnosis affects brain: new research

‘Hypnosis affects brain’, says new research. Apparently the brain shows ‘real effects’ from hypnosis that are not the same as relaxation. Here’s the story, first reported by BBC News:

Hypnosis has a “very real” effect that can be picked up on brain scans, say Hull University researchers.

An imaging study of hypnotised participants showed decreased activity in the parts of the brain linked with daydreaming or letting the mind wander.

The same brain patterns were absent in people who had the tests but who were not susceptible to being hypnotised.

One psychologist said the study backed the theory that hypnosis “primes” the brain to be open to suggestion.

Hypnosis is increasingly being used to help people stop smoking or lose weight and advisers recently recommended its use on the NHS to treat irritable bowel syndrome.

In the latest study, the team first tested how people responded to hypnosis and selected 10 individuals who were “highly suggestible” and seven people who did not really respond to the technique other than becoming more relaxed.

The participants were asked to do a task under hypnosis, such as listening to non-existent music, but unknown to them the brain activity was being monitored in the rest periods in between tasks, the team reported in the journal Consciousness and Cognition.

This shows that the changes were due to hypnosis and not just simple relaxation
