Neuroscience research has followed two distinct paths in investigating central neural mechanisms of pain and emotion. Theories of emotion and pain processing predict an interaction between pain and emotion, such that emotional states may serve to both increase or decrease pain. Theories of emotion view emotions as interpretations of bodily states and imply neuroanotomic relations between emotion and pain in the brain. Similarly pain neuromatrix theory predicts an affective dimension of pain experience that has been defined in terms of both pain unpleasantness and secondary affect, emphasizing the role of emotion in pain experience. In the present study, painful heat stimulation was applied to the face while simultaneously conducting whole brain imaging using functional magnetic resonance imaging (fMRI). In addition, personal episodes involving anger, fear, and neutral emotion were recalled during fMRI both with, and without, painful heat stimulation. The frontal cortex, cingulate cortex, and insula were shown to be involved in processing pain, anger, and fear, and these results compared favorably with findings in the literature. The results also demonstrated that simultaneous emotional episode recall modulated the patterns of brain activity involved in pain. Anger recall especially increased pain-related activity. This study allows greater understanding of the way that the brain's emotional processing networks for fear and anger are involved in the pain experience. Further application of these procedures to patients with chronic pain can aid understanding of the central pathological mechanisms involved.
