Kilohertz transcranial magnetic perturbation (ktmp) system

Abstract

A magnetic stimulation system includes a magnetic coil to generate an electric field of a magnitude having a desired effect on a brain, a voltage to current source to generate a current waveform having an amplitude and frequency to produce the electric field, and a controller to control the voltage to current source and to apply the current to the magnetic coil to provide perturbation of brain tissue using one or more periods of either continuously induced electric field with constant amplitude and frequency, or periods of electric field with at least one of amplitude and frequency modulation. A method of magnetically stimulating a brain includes placing a coil near a brain, and applying a current having an amplitude and frequency to the coil to produce an electric field having a desired effect on the brain, wherein the amplitude and frequency are applied using one of either one or more periods of continuously induced electric fields with constant amplitude and frequency, or periods of an electric field with at least one of either amplitude and frequency modulation.
