Effect of hypnosis on brain activity
Hypnosis training
1 hour hypnosis training prior to fMRI:
1. Progressive musclerelaxation
2. Autobiographic safeplace
3. Gloveanalgesia (2 buckets with hot and cold water) combined with autobiographic memory of analgesia.
4. Transferring analgesia to test region
5. Posthypnotic cues for fMRI session
No training in hyperalgesia

Pain and traumatic events
Often relation between pain and mental stress /traumatic events (divorce, workloads and
-shifts, severe disease and death in close family)
Reduced activity at work and at home
Reduced participation in social life
Poor sleep
Less exercise
Large consumption of painkillers-many side effects
Increased use of health care system
Depression
