A study by Derbshire, Whalley and Oakley ((2008) carried out an fMRI analysis of the hypnotic and non-hypnotic modulation of fibromyalgia pain.
The blog article reports:
‘This is the first published study to use fMRI to examine the effects of hypnotic and non-hypnotic suggestion upon brain activity. Thirteen patients suffering from fibromyalgia, a chronic pain condition, were given the same suggestions to increase and decrease their pain while in an fMRI scanner before and after they were hypnotised. Suggestion in both conditions produced significant changes in both pain experience and brain activity in pain-related regions. These activations were of greater magnitude, though, when suggestions followed a hypnotic induction - providing evidence for the greater efficacy of suggestion following a hypnotic induction.’
The image to the left here, taken from the Hypnosis and Suggestion blog, shows brain activity in response to both ‘hypnotic’ and ‘non-hypnotic’ suggestion in the same patients. You can clearly see that there is activity in both states, and that formal hypnotic induction significantly increased this activity.
This piece of research is particularly exciting to me because it investigates the power of suggestion with and without what we might call hypnotic trance.
I always tell my clients that, quite apart from the wonderful work that we do together in hypnosis in a session and the work that I ask them to do in self-hypnosis between sessions, the way that they talk to themselves in their own minds throughout the day is also incredibly important.
As you can see from the ‘unhypnotised’ image above, suggestions alone appear to stimulate brain activity. When you are talking to yourself inside your own head, make those suggestions positive and progressive.
Of course, we could get into an interesting debate here about what a ‘hypnotised’ versus an ‘unhypnotised’ state actually consists of; or what the brain activity shown on the scans actually means.
But what is important from a therapeutic point of view here is that all suggestion seems to activatea areas of the brain. This may have implications not just for working with the manipulation of pain - as in this study - but for so many other areas of our lives.
