neuromatrix theory

the theory that pain is produced by patterns of nerve impulses, or neurosignatures, that can be triggered not only by painful stimuli but also by other means, such as chronic stress. The theory attempts to account for such phenomena as phantom limb pain and chronic pain syndromes. See also gate-control theory. [proposed by Canadian psychologist Ronald Melzack (1929–  )]
