In transcranial magnetic stimulation, special coils create a fluctuating magnetic field that then generates a weak electrical field that can travel through the scalp and skull noninvasively. The electrical signal activates neurons in targeted parts of the brain—a complex electrical network itself. (Credit: Joseph Xu, Michigan Engineering Communications & Marketing)


The headpiece design is a big departure from today's figure 8-shaped devices made of just two coils. The researchers knew that in order to send a sharper signal, they'd have to change the shape of the fluctuating magnetic field the coils produce.
