Abstract: Described herein are devices, systems and methods to enhance the magnetic perturbation of a neuronal (e.g., brain) target during Transcranial Magnetic Stimulation (TMS), thereby enhancing the induced current in the target. In general, these devices, systems and methods enhance the magnetic perturbation (dB/dt) of the target by mechanically moving a TMS electromagnet (e.g. coil) at a frequency of greater than 1 kHz.

Abstract: Efficient use of multi-coil arrays for magnetic nerve stimulation depends upon coordinating the coil polarity, the pulse phase and the pulse timing. Monophasic magnetic nerve stimulators produce more precise and predictable results in the stimulation of nerves than biphasic and polyphasic machines, but are less electrically efficient, and consequently limited in terms of pulse train speed. The present invention concerns the coordination of pulse polarity, phase, timing, and strength between multiple magnetic stimulation coils. The goal is to optimize the manner in which multiple coils may be used synergistically to control the activity of underlying neural tissue.
