Approaching Pain's Layers Through Hypnosis (The Scientist)

Under the suggestive power of hypnosis, subjects can be convinced that they're feeling pain when no stimulus is given. Other subjects can be taught to control the amount of pain they feel, as with a dial. Appearing to work well in as many as 15% of people tested, hypnosis can tap into the brain's ability to produce and modulate pain as well as the maddening subjectivity of the experience. Using sophisticated brain imaging techniques in concert with the power of suggestion, scientists are getting closer to parsing the emotional and sensory aspects of pain.
