Examination of the Influence by the Stimulation Coil Arrangement and the Shape of the Stimulation Object in the Transcranial Magnetic Stimulation Using a Model

Abstract

The magnetic stimulation is the way of stimulating the nervous and muscle tissue with the electric field induced by the stimulation coil and is widely used in the evaluation of the nervous system and the field of the exercise physiology. The focality and the deep stimulation efficiency of the magnetic stimulation are affected by the coil arrangement and shape of the stimulated object since the induced electric field distribution is varied by them. In this study, we used the 5 layers head model and estimated the induced electric field distribution by calculation. As the result, the induced electric field distribution is mostly affected by the boundary between different tissues which have different conductivities.
