Research on the neural substrates of emotion has found evidence for cortical asymmetries for aspects of emotion. A recent article by Nicholls et al. has used a new imaging method to interrogate facial movement in 3D to assess possible asymmetrical action during expressions of happiness and sadness. Greater left-sided movement, particularly during expressions of sadness was observed. These findings have implications for understanding hemispheric differences in emotion and lend support to the notion that aspects of emotion processing might be differentially localized in the two hemispheres.
对情绪神经基础的研究已经发现了情绪各方面存在皮质不对称性的证据。尼科尔斯等人最近发表的一篇文章使用了一种新的成像方法对面部运动进行三维分析，以评估在表达快乐和悲伤时可能存在的不对称动作。研究观察到左侧运动更为明显，尤其是在悲伤表情期间。这些发现对于理解情绪的半球差异具有重要意义，并支持了情绪加工的各个方面可能在两个半球中存在差异定位的观点。
