Abstract

In this study the effects of a realistic head geometry and coil position on the spatial distribution of induced electric field, under TMS, have been investigated using statistical modalities such as RDM, MAG and CC. It has also been observed that the secondary electric field, caused by the asymmetry of the geometry, leads to a dramatic drop in E-field magnitude, deviation in field focality and accelerates its decay. The results show that the head geometry and coil position play a significant role in shaping the spatial distribution of induced electric field.
