这项研究验证了一个假设，即情绪的识别将利用解剖学上可分离的大脑区域，这取决于刺激是静态的还是明确传达的有关行动的信息。我们在一个罕见的双侧脑损伤患者B中研究了这一假设，通过管理任务，评估识别和命名的情绪，从视觉和语言刺激，其中一些描绘的行动，其中一些没有。B。当情绪被显示为静态图像或被赋予单一的语言标签时，除了快乐，他们无法识别任何主要情绪。相比之下，除了厌恶这个显著的例外，他从动态的面部表情和描述动作的故事中正确地识别出了主要情绪。我们的研究结果与以下观点一致，即关于行动的信息是在枕顶和背侧额叶皮质中处理的，所有这些在B中都是完整的。的大脑。这些信息随后将与有关情绪的知识联系起来，情绪取决于映射躯体状态的结构，其中许多结构在B中也是完整的。的大脑。然而，这些躯体感觉结构中的一个，即丘脑，双侧受损，可能是B的原因。的一致受损识别厌恶（从静态和动作刺激）。B中损坏的其他结构。的大脑，包括双侧下颞叶、前颞叶和内侧额叶皮质，似乎是将静态刺激的感知与情绪识别联系起来的关键。因此，根据刺激的属性，有关情绪的知识的提取依赖于广泛分布的、部分不同的神经结构集。(C)2003 Elsevier Science（美国）。All rights reserved.
This study tested the hypothesis that the recognition of emotions would draw upon anatomically separable brain regions, depending on whether the stimuli were static or explicitly conveyed information regarding actions. We investigated the hypothesis in a rare subject with extensive bilateral brain lesions, patient B., by administering tasks that assessed recognition and naming of emotions from visual and verbal stimuli, some of which depicted actions and some of which did not. B. could not recognize any primary emotion other than happiness, when emotions were shown as static images or given as single verbal labels. By contrast, with the notable exception of disgust, he correctly recognized primary emotions from dynamic displays of facial expressions as well as from stories that described actions. Our findings are consistent with the idea that information about actions is processed in occipitoparietal and dorsal frontal cortices, all of which are intact in B.'s brain. Such information subsequently would be linked to knowledge about emotions that depends on structures mapping somatic states, many of which are also intact in B.'s brain. However, one of these somatosensory structures, the insula, is bilaterally damaged, perhaps accounting for B.'s uniformly impaired recognition of disgust (from both static and action stimuli). Other structures that are damaged in B.'s brain, including bilateral inferior and anterior temporal lobe and medial frontal cortices, appear to be critical for linking perception of static stimuli to recognition of emotions. Thus the retrieval of knowledge regarding emotions draws upon widely distributed and partly distinct sets of neural structures, depending on the attributes of the stimulus.
