Here is a link to a post from mayoclinic.com about TMS and how it works. I am curious about who the authors are for this article, I posted about the article that first introduced me to TMS and that article came out of the Mayo Clinic.
Mayoclinic.com
Explores the science and clinical applications of central neuromodulation techniques including transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS).
