The occurrence of mislocalizations was correlated with a detailed psychophysical examination in which sensory, motor and autonomic symptoms were assessed and support the concept of pain–induced reorganization in the somatosensory system of CRPS patients.

The pattern of cortical deactivation during allodynia may hint at a shift of activation from tonically active sensory systems, like visual and vestibular cortices, into somatosensory-related brain areas.

In complex regional pain syndrome (CRPS), functional imaging studies gave evidence for an important role of the central nervous system (CNS) in the pathogenesis of the disease, leading to an altered central processing of tactile and nociceptive stimuli and an altered cerebral organization of movement.

The fMRI findings showing the cortical reorganization in a patient with type 2 CRPS were compared and showed significantly increased abnormal cortical responses on the primary and secondary somatosensory areas and the distinct parietal association area on the contra-lateral side of the brain to the stimuli on the affected painful hand.

The findings suggest that the wide variety of symptoms encompassing the sensory and motor systems of patients with CRPS are associated with microstructural impairment of the secondary motor area, which receives sensory information and projects motor information.

Diminished perception of innocuous and noxious stimuli is associated with altered activity in many parts of the somatosensory pathway or other supraspinal areas, and cortical findings indicate a neurobiological component for at least part of the symptoms in patients presenting with nondermatomal somatoensory deficits.

Prefrontal activation is interpreted as a consequence of attention, cognitive evaluation, and planning of motor behavior in response to pain, and the lack of activation of the anterior cingulate contrasts with physiologic pain after C-nociceptor stimulation.
