TMS-evoked long-lasting artefacts: a new adaptive algorithm for EEG signal correction

In the last twenty years, the combination of transcranial magnetic stimulation (TMS) and electroencephalography (EEG) has provided new insights into the investigation of brain dynamics (Ilmoniemi and Kičić, 2010). However, besides the potential of combining these two techniques, their simultaneous use produces different EEG artefacts of electrical and physiological nature. Electrical artefacts result from the voltage induced in the electrodes by the TMS pulse, which is several orders of magnitude larger than the physiological responses (Virtanen et al., 1999).
