If you would like to see these superb research results "in print", look at the May '99 issue of the American Journal of Psychiatry.  Your local hospital may well have it, if they have even a tiny library with public access, because the journal is one of the most important in psychiatry.   

The cover, the lead editorial and the lead article are all devoted to this work by Helen Mayberg, M.D., and her colleagues at the Research Imaging Center and the Departments of Psychiatry, Neurology, and Radiology, University of Texas Health Science Center at San Antonio.  (Dr.  Mayberg has since moved on to the Rotman Research Institute in Toronto, Canada).
