چکیده :

n this paper, we examine the effectiveness of thetemporal interference method through simulations and experi-ments on phantom models. In this method, the electrodes areplaced on the scalp, and no physical damage is done to thesubject. In contrast to other non-invasive stimulation methods inwhich a large part of the brain might be under the influence ofthe stimulation, the TI method not only has the ability to focus thestimulation at a specific point (with a certain resolution), but alsoit can move the stimulated spot. In the simulations, we study thecurrent interference pattern inside the human head model, andwe use the Hodgkin–Huxley model to map action potentials in oursimulations. Moreover, we study the effect of different parameterson how to move the stimulation spot. Our simulation results areverified against experimental measurements on a phantom.
