Transcranial magnetic stimulation (TMS) and neuroimaging studies suggest a functional link between the emotion-related brain areas and the motor system. It is not well understood, however, whether the motor cortex activity is modulated by specific emotions experienced during music listening. In 23 healthy volunteers, we recorded the motor evoked potentials (MEP) following TMS to investigate the corticospinal excitability while subjects listened to music pieces evoking different emotions (happiness, sadness, fear, and displeasure), an emotionally neutral piece, and a control stimulus (musical scale). Quality and intensity of emotions were previously rated in an additional group of 30 healthy subjects. Fear-related music significantly increased the MEP size compared to the neutral piece and the control stimulus. This effect was not seen with music inducing other emotional experiences and was not related to changes in autonomic variables (respiration rate, heart rate). Current data indicate that also in a musical context, the excitability of the corticomotoneuronal system is related to the emotion expressed by the listened piece.
经颅磁刺激（TMS）和神经影像学研究表明，情绪相关脑区与运动系统之间存在功能联系。然而，运动皮层的活动是否受到音乐聆听过程中特定情绪的调节还不是很清楚。在 23 名健康志愿者中，我们记录了 TMS 后产生的运动诱发电位（MEP），以研究在受试者聆听引发不同情绪（快乐、悲伤、恐惧和不快）、情绪中性的音乐和控制刺激（音阶）时皮质脊髓兴奋性的变化。在另一组 30 名健康受试者中，我们预先评估了情绪的质量和强度。与中性音乐和控制刺激相比，与恐惧相关的音乐显著增加了 MEP 的大小。这种效应在诱导其他情绪体验的音乐中没有出现，也与自主变量（呼吸频率、心率）的变化无关。目前的数据表明，即使在音乐环境中，皮质运动神经元系统的兴奋性也与所听音乐表达的情绪有关。
