The term central sensitization has been created to describe the neurobiological notion that those predisposed to somatization have an overly sensitive neural network. Somatization is the expression of mental phenomena as physical (somatic) symptoms. Disorders characterized by somatization extend in a continuum from those in which symptoms develop unconsciously and nonvolitionally to those in which symptoms develop consciously and volitionally.
