Deep transcranial magnetic stimulation (Deep TMS) is a non-invasive technique for excitation of large populations of neurons in the brain.
Use
Deep TMS uses the basic principles of transcranial magnetic stimulation (TMS) but expands them from the use of a single focal stimulation source to a summation of several simultaneous operating elements. The brain regions affected directly by this technique are determined by the shape of the TMS coil. Standard TMS coils induce direct stimulation of superficial brain areas, while Deep TMS coils (H-coils) induce summation of fields, allowing deeper penetration of the brain. To affect different areas of the brain (depending on the targeted disorder), specific versions of H-coils are installed within a helmet placed on the subject's head.
Deep TMS coils have been studied in healthy humans and people with major depressive disorder, autism, bipolar disorder, auditory hallucinations, and schizophrenia.
History
The technology was developed by Abraham Zangen and Yiftach Roth starting in 2001 and a patent was filed by the United States National Institutes of Health. In January 2013, the United States Food and Drug Administration permitted a manufacturer to market a Deep TMS device that was indicated for the treatment of depressive episodes in adult patients suffering from major depressive disorder who failed to achieve satisfactory improvement from previous anti-depressant medication treatment in the current episode.
