Mapping Brain Response to Pain in Fibromyalgia Patients Using Temporal Analysis of fMRI
Figure 4
Comparison of fibromyalgia patients with healthy subjects matched for subjective pain levels.
The statistical parametric map (SPM) adjusted for response duration shows the regions where patients receiving 4 kg/cm2 of pressure showed greater activation than control subjects receiving 6.8 kg/cm2. Display threshold, P<0.01, 10 voxels. L indicates left hemisphere. The names of the regions are shown in Table 4.
