The simplest answer is that deep TMS therapy affects a deeper part of the brain compared to its standard counterpart; in fact, it goes about twice as deep.

With regular TMS therapy, we rely on a two-coil device to deliver electricity through copper wires, creating a magnetic reaction. This reaction is strongest at the point where the coils touch. The magnetic spot is put on the dorsal lateral pre-frontal cortex, either the left or the right side depending on the nature of the patient’s depression. The magnetic pull stimulates an area of the brain comparable to an American silver dollar and as deep as 2 to 3 centimeters.

Deep TMS therapy, developed by a physicist in Jerusalem, differs considerably: In this process, the coils are designed in such a configuration that it enables the magnetic stimulation to reach as deep as 6 to 7 centimeters into the patient’s brain. It also affects the diameter of the affected area, covering a substantial amount of the brain with every pulse.
