在看电影时，大脑将视觉信息和音乐声整合成一个连贯的记忆。多感觉整合可以导致情绪的诱发，其中声轨效价可能具有调节性影响。在这里，在功能性磁共振成像扫描期间，向22名参与者（13名女性）展示浪漫喜剧中的动态接吻场景。接吻的场景要么伴随着快乐的音乐，要么伴随着悲伤的音乐，要么没有音乐。来自跨通道研究的证据激发了一个预定义的三区域网络，用于多感觉情绪整合，包括梭状回（FG），杏仁核（AMY）和前上级颞回（aSTG）。在这个网络中的相互作用进行了研究，使用动态因果模型的有效连接。这揭示了快乐和悲伤音乐的双线性调制，对FG和AMY到aSTG的连接具有抑制作用。非线性动态因果模型显示aSTG对梭状核-杏仁核连接的抑制性门控效应。总之，梭状核杏仁核耦合强度调制通过反馈通过aSTG作为区域的多感觉整合的情感材料。这种机制是情绪特异性的，在悲伤的音乐中更为明显。因此，音轨效价可能会调节电影中的情绪诱导差异改变预处理的视觉信息的杏仁核。
While watching movies, the brain integrates the visual information and the musical soundtrack into a coherent percept. Multisensory integration can lead to emotion elicitation on which soundtrack valences may have a modulatory impact. Here, dynamic kissing scenes from romantic comedies were presented to 22 participants (13 females) during functional magnetic resonance imaging scanning. The kissing scenes were either accompanied by happy music, sad music or no music. Evidence from cross-modal studies motivated a predefined three-region network for multisensory integration of emotion, consisting of fusiform gyrus (FG), amygdala (AMY) and anterior superior temporal gyrus (aSTG). The interactions in this network were investigated using dynamic causal models of effective connectivity. This revealed bilinear modulations by happy and sad music with suppression effects on the connectivity from FG and AMY to aSTG. Non-linear dynamic causal modeling showed a suppressive gating effect of aSTG on fusiform-amygdalar connectivity. In conclusion, fusiform to amygdala coupling strength is modulated via feedback through aSTG as region for multisensory integration of emotional material. This mechanism was emotion-specific and more pronounced for sad music. Therefore, soundtrack valences may modulate emotion elicitation in movies by differentially changing preprocessed visual information to the amygdala.
