TRANSCRANIAL MAGNETIC STIMULATION SYSTEM AND METHODS
First Claim
1. A coil for magnetic stimulation of a target area, the coil positionable on a body part, the coil comprising:
- a base portion comprising at least one member for providing electrical current flow in a direction tangential to the target area, said base portion positioned at a first level with respect to the target area;
a protruding return portion for carrying returning current in a direction opposite the target area, said protruding return portion in electrical communication with said at least one member and positioned at a second level with respect to the target area, the second level located at a distance above the first level; and
a contacting return portion for carrying returning current in a direction opposite the target area, said contacting return portion in electrical communication with said at least one member and positioned substantially in the first level and spaced at a distance from the target area.

Abstract
A system and methods for transcranial magnetic stimulation, the system including a helmet, a positioning portion, a stimulator and a cooling system, are disclosed. The helmet includes a coil for deep brain magnetic stimulation. The coil has a base portion, and return portions, which may include a protruding return portion and a contacting return portion. The coil is designed to minimize unintended stimulation of portions of the brain, while reducing accumulation of surface charges. The coil is stimulated at several locations and/or at different times so as to focus the electrical field on a specific deep neuronal structure.
