TMS
I checked the Discover magazine website and it looks like they don't go back that far.
Anyhow, I did a search or two and found the name of the device.....
It is called TMS-stands for Transcranial Magnetic Stimulation. I think the FDA is still testing it. Anyhow-it involves no drugs and is harmless-not a magic sure, but it seem to really help a significant percentage of people who have tried it.
