TMS (Transcranial Magnetic Stimulation) is a noninvasive method of stimulating nerve cells. This is based on electromagnetic induction that induces an electric field to the brain tissue using a time varying magnetic field. Furthermore, TMS can change the activity of the remote site locally, with neuronal activity. Magnetic stimulation by TMS, a number of studies have been conducted to explore the therapeutic potential of TMS in the treatment of various psychiatric diseases and the effect has been confirmed. Although TMS is widely used in neurophysiology and cognitive studies, it is not known yet which nerve cells are stimulated during TMS. Despite the large number of studies investigating the efficacy of TMS, there are still many uncertainties about the mechanisms that alter cortical activity and how it relates to therapeutic effects. In this research, for the study of unresolved items, we clarify the basic functional basis of TMS and explain cable theory in case of electromagnetic induction.
