- Abstract
Emotion is assumed to facilitate the preparation of behavioral responses to environmental stimuli. In the present study, we examined whether emotional processing induced by spoken scenarios of positive and negative content, related to the self or to other people, modulates corticospinal excitability. Motor evoked potentials (MEPs) elicited by transcranial magnetic stimulation (TMS) in 20 volunteers indicated that processing of negative emotional content increased MEP amplitude, regardless of the perspective taken in the scenario. By contrast, positive emotional processing did not reliably alter MEP amplitude. These results provide the first TMS evidence that the auditory processing of emotionally negative information triggers action preparation.
