Koch G. The new era of TMS-EEG: Moving towards the clinical practice // Clinical neurophysiology: official journal of the International Federation of Clinical Neurophysiology. — 2019. — Т. 130. — №5. — С. 791.

After its introduction by the seminal works of Cracco et al. (1989) and Ilmoniemi et al. (1997), recording of TMS evoked brain responses by EEG is increasingly gaining consideration as a powerful tool to investigate key physiological aspects of neuronal activity in the human cortex. 

While, in the past, this technique was extremely challenging and its use was constrained to a few experimental laboratories, the advent of novel advanced amplifiers with high sampling rates and the development of TMS-compatible EEG electrodes that minimized the TMS-induced artifacts has made the spread of this fascinating method possible for studying brain activity at numerous clinical research centers around the world. 

In this issue of Clinical Neurophysiology, a panel of experts in the use of TMS-EEG provide an extensive overview on the recent advances, highlighting the clinical utility of TMS-EEG (Tremblay et al., 2019). In particular, TMS-EEG is viewed as a reliable method for studying neurophysiological markers of healthy brain function, and the potential diagnostic and prognostic utility in clinical populations is discussed.
