Abstract:
We present an overview on the technical, biophysical, and physiological fundamentals of transcranial magnetic stimulation (TMS). Starting with the stimulator technique and the active principle of TMS we illustrate the time course of a stimulation pulse and the spatial distribution of the induced fields. Based on threshold measurements transformation factors are given that allow the comparison of stimulation intensities using different stimulators. We discuss the comparability of technical parameters known from magnetic resonance imaging and TMS. Finally, we give an brief overview on putative further developments.
