Previous human imaging studies have revealed a network of brain regions involved in the
processing of allodynic pain; this includes prefrontal areas, insula, cingulate cortex, primary
and secondary somatosensory cortices and parietal association areas. In this study, the
neural correlates of the perceived intensity of allodynic pain in neuropathic pain patients
were investigated. In eight patients, dynamic mechanical allodynia was provoked and brain
responses recorded using functional magnetic resonance imaging (fMRI). Voxels in which …
