本研究使用愉快和不愉快的音乐来唤起情绪，并用功能磁共振成像(FMRI)来确定情绪处理的神经关联。不愉快的(永久不和谐的)音乐与愉快的(协和的)音乐相比，杏仁核、海马体、海马旁回和颞极被激活。这些结构以前被认为与具有(负)情绪效价的刺激的情绪处理有关；目前的数据表明，由这些结构组成的大脑网络可以在感知听觉(音乐)信息的过程中被激活。悦耳的音乐表现为额叶下回(IFG、下布罗德曼区(BA)44、BA 45和BA 46)、前上岛、腹侧纹状体、Heschl回和罗兰迪氏盖的激活。IFG的激活似乎反映了音乐句法分析和工作记忆操作的过程。罗兰迪克顶叶区域的激活可能反映了在感受到悦耳的曲调时镜像功能机制的激活。前额叶、前上岛和腹侧纹状体可形成运动相关的环路，用于在感知愉悦听觉信息的过程中形成发声的(运动前)表征。在所有上述结构中，除海马体外，在音乐刺激的呈现过程中，激活随着时间的推移而增加，这表明情绪加工的影响具有时间动力学；到目前为止，情绪的时间动力学在功能成像文献中主要被忽略。
The present study used pleasant and unpleasant music to evoke emotion and functional magnetic resonance imaging (fMRI) to determine neural correlates of emotion processing. Unpleasant (permanently dissonant) music contrasted with pleasant (consonant) music showed activations of amygdala, hippocampus, parahippocampal gyrus, and temporal poles. These structures have previously been implicated in the emotional processing of stimuli with (negative) emotional valence; the present data show that a cerebral network comprising these structures can be activated during the perception of auditory (musical) information. Pleasant (contrasted to Unpleasant) music showed activations of the inferior frontal gyrus (IFG, inferior Brodmann's area (BA) 44, BA 45, and BA 46), the anterior superior insula, the ventral striatum, Heschl's gyrus, and the Rolandic operculum. IFG activations appear to reflect processes of music-syntactic analysis and working memory operations. Activations of Rolandic opercular areas possibly reflect the activation of mirror-function mechanisms during the perception of the pleasant tunes. Rolandic operculum, anterior superior insula, and ventral striatum may form a motor-related circuitry that serves the formation of (premotor) representations for vocal sound production during the perception of pleasant auditory information. In all of the mentioned structures, except the hippocampus, activations increased over time during the presentation of the musical stimuli, indicating that the effects of emotion processing have temporal dynamics; the temporal dynamics of emotion have so far mainly been neglected in the functional imaging literature.
