Abstract

In this paper, we present a numerical simulation of transcranial magnetic stimulation in a real 3D child head model by employing a realistic figure-of-eight coil. The induced electric fields were calculated by impedance method and the results were compared with those obtained in an adult head model. It was found the electric fields present the maximum values in the scalp for both child and adult head models. While the electric fields decay quickly in child brain than that in adult brain. The TMS efficacy is reduced in child head compared to that in adult head.
