Modeling of the induced electric field in deep magnetic stimulation in anatomical head models

Aim of this study is to characterize the E distributions due to the H1 coil, developed for the Deep Transcranial Magnetic Stimulation, in the brain of two realistic human models by computational electromagnetic techniques. Despite inter-individual differences, our results show that the dorsolateral prefrontal cortex is the region preferentially stimulated by H1 coil when they it is placed in the position on the scalp adopted in this study, with a broad and non-focal distribution. Moreover, the H1 coil spread also both in the prefrontal and medial prefrontal cortex and towards some deeper brain structures.
