Abstract

The Transcranial Magnetic Stimulation (TMS) is a non-invasive stimulation process which induces an electric field in the brain, to excite or inhibit groups of neurons. However, the current technology reaches only the motor cortex, about 1.5 cm deep, thus greatly restricting the areas of stimulation. This paper proposes a new geometry of TMS coil to reach further internal brain structures, such as the basal ganglia, with improved focality.
