Tonal music is characterized by a continuous flow of tension and resolution. This flow of tension and resolution is closely related to processes of expectancy and prediction and is a key mediator of music-evoked emotions. However, the neural correlates of subjectively experienced tension and resolution have not yet been investigated. We acquired continuous ratings of musical tension for four piano pieces. In a subsequent functional magnetic resonance imaging experiment, we identified blood oxygen level-dependent signal increases related to musical tension in the left lateral orbitofrontal cortex (pars orbitalis of the inferior frontal gyrus). In addition, a region of interest analysis in bilateral amygdala showed activation in the right superficial amygdala during periods of increasing tension (compared with decreasing tension). This is the first neuroimaging study investigating the time-varying changes of the emotional experience of musical tension, revealing brain activity in key areas of affective processing.
调性音乐的特点是紧张感与舒缓感的持续流动。这种紧张感与舒缓感的流动与期待和预测过程密切相关，并且是音乐诱发情感的关键调节因素。然而，主观体验到的紧张感与舒缓感的神经关联尚未得到研究。我们获取了对四首钢琴曲的音乐紧张感的连续评分。在随后的功能磁共振成像实验中，我们发现左侧眶额外侧皮质（额下回眶部）存在与音乐紧张感相关的血氧水平依赖信号增强。此外，对双侧杏仁核的感兴趣区域分析显示，在紧张感增强期间（与紧张感减弱相比），右侧杏仁核浅层有激活。这是第一项研究音乐紧张感情感体验随时间变化的神经影像学研究，揭示了情感处理关键区域的大脑活动。
