从面部表情中识别情感需要在大量神经结构中实现的各种心理过程。情绪感知的大脑侧化主要有两种理论：（1）右半球假说（RHH）和（2）效价特异性假说（VSH）。为了测试这些偏侧化模型，我们进行了一个大型的基于体素的荟萃分析，目前的功能性磁共振成像（fMRI）的研究，采用健康志愿者的情绪面孔范式。两名独立的研究人员进行了单独的全面PUBMED（1990年至2008年5月）搜索，以找到所有功能性磁共振成像研究，使用健康受试者的情绪面孔范式的变体。在最初确定的551项研究中，105项研究符合纳入标准。整个数据库由1785个脑坐标组成，产生1600名健康受试者的总体样本。我们发现没有支持的假设，整体右侧化的情绪处理。相反，在所有的情绪条件下，海马旁回和杏仁核，梭状回，舌回，楔前叶，枕下回和枕中回，后扣带回，颞中回，额下回和上级额回双侧激活（p = 0.001）。在左杏仁核的负面情绪处理过程中，大脑反应存在效价特异性偏侧化（p = 0.001）。显着的相互作用的方法和避免尺寸和前额叶反应进行了观察（p = 0.001）。(c)2009爱思唯尔爱尔兰有限公司保留所有权利。
Recognizing emotion from facial expressions draws on diverse psychological processes implemented in a large array of neural structures. Two major theories of cerebral lateralization of emotional perception have been proposed: (i) the Right-Hemisphere Hypothesis (RHH) and (ii) the Valence-Specific Hypothesis (VSH). To test these lateralization models we conducted a large voxel-based meta-analysis of current functional magnetic resonance imaging (fMRI) studies employing emotional faces paradigms in healthy volunteers. Two independent researchers conducted separate comprehensive PUBMED (1990-May 2008) searches to find all functional magnetic resonance imaging studies using a variant of the emotional faces paradigm in healthy subjects. Out of the 551 originally identified studies, 105 studies met inclusion criteria. The overall database consisted of 1785 brain coordinates which yield an overall sample of 1600 healthy subjects. We found no support for the hypothesis of overall right-lateralization of emotional processing. Conversely, across all emotional conditions the parahippocampal gyrus and amygdala, fusiform gyrus, lingual gyrus, precuneus, inferior and middle occipital gyrus, posterior cingulated, middle temporal gyrus, inferior frontal and superior frontal gyri were activated bilaterally (p = .001). There was a valence-specific lateralization of brain response during negative emotions processing in the left amygdala (p = 0.001). Significant interactions between the approach and avoidance dimensions and prefrontal response were observed (p = 0.001). (c) 2009 Elsevier Ireland Ltd. All rights reserved.
