Using positron emission tomography we explored brain regions activated during the perception of face expressions, emotional voices and combined audio-visual pairs. A convergence region situated in the left lateral temporal cortex was more activated by bimodal stimuli than by either visual only or auditory only stimuli. Separate analyses for the emotions happiness and fear revealed supplementary convergence areas situated mainly anteriorly in the left hemisphere for happy pairings and in the right hemisphere for fear pairings indicating different neuro-anatomical substrates for multisensory integration of positive versus negative emotions. Activation in the right extended amygdala was obtained for fearful faces and fearful audio-visual pairs but not for fearful voices only. These results suggest that during the multisensory perception of emotion, affective information from face and voice converge in heteromodal regions of the human brain.
我们使用正电子发射断层扫描技术，探究了在对面部表情、情感声音以及视听组合刺激进行感知时被激活的脑区。位于左侧颞叶皮质的一个汇聚区，对双峰刺激的激活程度高于仅视觉或仅听觉刺激。对幸福和恐惧情绪的单独分析显示，幸福配对时主要在左半球前部、恐惧配对时主要在右半球存在额外的汇聚区，这表明积极情绪与消极情绪的多感官整合存在不同的神经解剖学基础。仅恐惧声音未激活右侧扩展杏仁核，但恐惧面部和恐惧视听组合刺激激活了该区域。这些结果表明，在对情绪进行多感官感知过程中，来自面部和声音的情感信息在人类大脑的异模态区域汇聚。
