Association of the N100 TMS-evoked potential with attentional processes: A motor cortex TMS–EEG study

Published in: Brain and Cognition, Volume 122, April 2018, 9-16 Abstract “The most thoroughly studied transcranial magnetic stimulation (TMS)-evoked electroencephalogram (EEG) potential (TEP), N100, is often defined as a measure of cortical inhibition. We explored the association of the N100 amplitude with attention in 51 young healthy adults. Navigated TMS with simultaneous EEG registering was applied over the left primary motor cortex at the intensity of 110% of the resting motor threshold. Attention was assessed with the Paced Auditory Serial Addition Test (PASAT). We found a negative Pearson correlation (p = .023, r = −0.317) between the left centroparietal N100 amplitude and the PASAT score. Of… Read More
