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

Modulation of sensorimotor circuits during retrieval of negative Autobiographical Memories: Exploring the impact of personality dimensions

Published in: Neuropsychologia, Volume 110, February 2018, 190-196 Abstract “Autobiographical Memory (AM) retrieval refers to recollection of experienced past events. Previous Transcranial Magnetic Stimulation (TMS) studies have shown that presentation of emotional negative stimuli affects human motor cortexexcitability resulting in larger motor evoked potentials (MEPs). Up to date no TMS studies have been carried out in order to investigate the effect of personal memories with negative emotional value on corticospinal excitability. In this study we hypothesized that negative AM retrieval will modulate corticomotor excitability and sensorimotor integration as determined by TMS neurophysiological parameters. Furthermore, we investigated whether TMS responses during retrieval of negative AM are associated with… Read More
