文摘
- •
We assessed repetition suppression in three TMS-induced responses; resting and active MEPs and corticospinal silent period.
- •
Repetition suppression was confirmed in resting MEPs in accordance with earlier studies.
- •
Active MEPs did not exhibit the phenomenon, SPs, on the other hand, lengthened in duration.
- •
Repetition suppression might result from increased activation of GABAergic interneurons influencing on the SP duration.
