The concept that the perception of a stimulus as being painful requires activity in parts of the cerebral cortex has gained universal recognition within the past 10 years. 28 The large number of functional imaging studies in humans, appearing during that period, have greatly contributed to this development by showing consistent evidence for activation of various cortical areas by painful stimuli, including the primary and secondary somatosensory cortex, the insula, the anterior cingulate gyrus, and prefrontal cortical areas. Thus, the sense of pain—like all other senses— has a representation within the cerebral cortex. These imaging studies, however, did not reveal the pathways by which a p…
