1. A Transcranial Magnetic Stimulation (TMS) system for stimulating a patient'"'"'s neuronal tissue while avoiding undesirable side effects on non-target regions adjacent to the magnet, the system comprising:
- a TMS electromagnet configured to apply Transcranial Magnetic Stimulation to the patient, wherein the TMS electromagnet includes a front face and a back face; and
a shielding enclosure for partially enclosing the TMS electromagnet, wherein the shielding enclosure is configured to prevent or limit the emission of a magnetic field into adjacent tissue from the back face of the TMS electromagnet.

Abstract
System and methods for Transcranial Magnetic Stimulation (TMS) are described in which regions adjacent (e.g., to the sides and behind the TMS electromagnet) are protected from the high magnetic fields emitted by the TMS electromagnet. Thus, adjacent muscle or neural structures are protected and undesirable side effects are avoid or minimized, allowing stimulation from previously unavailable sites such as the mouth and pharynx.

9. A Transcranial Magnetic Stimulation (TMS) system for stimulating a patient'"'"'s neuronal tissue while avoiding undesirable side effects on non-target regions adjacent to the magnet, the system comprising:
-
a TMS electromagnet configured to apply Transcranial Magnetic Stimulation to the patient, wherein the TMS electromagnet includes a back face and a front face; and a shielding enclosure configured to partially enclose the TMS electromagnet, wherein the shielding enclosure is formed of a high magnetic permeability material, and further wherein the shielding enclosure is configured to modify the magnetic field emitted by the TMS electromagnet to attenuate the magnetic field emitted through the shielding enclosure from the back face of the TMS electromagnet; wherein the shielding enclosure and TMS electromagnet are configured to be combined and placed within a patient'"'"'s mouth or pharynx. - View Dependent Claims (10, 11, 14, 15)

16. A method for Transcranial Magnetic Stimulation (TMS) of a neuronal target, the method comprising:
-
positioning a shielded TMS electromagnet in a patient'"'"'s mouth or pharynx, wherein the shielded TMS electromagnet comprises a TMS electromagnet partially surrounded by a shielding enclosure comprising a high magnetic permeability material configured to attenuate the magnetic field emitted through the shielding enclosure from the TMS electromagnet; and emitting an electromagnetic field from the front of the TMS electromagnet through the patient'"'"'s mouth or pharynx and into the brain to stimulate a neuronal target. - View Dependent Claims (17, 18, 19)
