Abstract

Transcranial magnetic stimulation (TMS) is a non-invasive method for stimulating the cortical neurons in the brain. The eddy current distribution is induced by the time-varying magnetic field of the magnetic coil used in the TMS. The brain neurons can be excited by the eddy current stimulation. The figure-of-eight coil in the TMS is used for the focal stimulation. The brain site beneath the central point of the figure-of-eight coil is conventionally determined as the stimulating site. However, it is difficult to find the optimal position to be stimulated by changing the coil. In this study, we propose an optimization method of the current distribution using a magnetic substance, without varying the coil’s position. We verify our method by a computer simulation.
