| Comparing baseline scans
during pain with scans taken after stimulation, when the patient had
become pain-free, revealed significant rCBF increases in the prefrontal

chronic pain | R. C. Kupers; J. M. Gybels; Albert Gjedde. Positron emission tomography study of a chronic pain patient successfully

condition, as compared to the neutral, increased rCBF in the right
