Sherry,
Sorry how late I'm jumping in here on the conversation (been very busy at the hospital). However, I can confirm that study is being done on whether magnetic fields could be useful in the treatment of depression and other emotional disorders. I've spoken personally with at least one neurologist at the University of Florida who is looking into the possibility. Seems they are using magnets similar to those used in MRI, but with even higher Tesla strength (if I remember correctly), and that can be focused on small areas. One of the advantages UF has is they have access to the the high energy magnet lab being developed at Florida State University in Tallahassee. I had heard others were looking into the possibilities, but wasn't familiar with the work at Pennsylvania. Thanks for bringing it up.
