Summary
Volunteers placed a hand in hot water while their brains were scanned. Under hypnosis, they were given suggestions that the heat would feel more unpleasant, or less unpleasant — while the actual temperature stayed the same.
Their ratings of how unpleasant the pain was changed with the suggestion, and so did activity in the anterior cingulate cortex. The primary sensory cortex, which registers the raw sensation, did not change.
Key finding
Suggestion changed the emotional brain response to pain, not the sensory one.
Why this matters
How much something 'hurts' is partly about meaning. When we change the meaning held in the subconscious, the emotional charge of an experience can change too.
Research is summarised in plain language for a general audience. Hypnotherapy and energy healing are complementary approaches and are not a substitute for medical or psychiatric care.
