[Functional imaging of pain: from the somatic response to emotions].

Functional brain imaging in subjects experiencing pain (real, observed or imagined) has led to considerable progress in our understanding of the role of the brain andpsyche in pain integration and control, as well as some forms of somatoform pain with no anatomical basis. This research is challenging not only the dichotomy between the soma and psyche, but also the concept of psychosomatic pain.
