Several brain areas that constitute the neural matrix of pain can be activated by noxious stimuli and by pain-relevant cues, such as pictures, facial expressions, and pain-related words. Although chronic pain patients are frequently exposed to pain-related words, it remains unclear whether their pain matrix is specifically activated during the processing of such stimuli in comparison to healthy subjects.
