岛叶皮层被认为是通过内感受感受情绪的重要区域。大多数报告岛叶在整合内感受和情绪中的作用的研究都使用了神经影像技术，例如功能性磁共振成像（fMRI）；然而，神经心理学研究有限。岛叶病变对情绪和内感受的影响尚未得到适当的研究。在这项研究中，我们通过比较与岛叶相关的神经胶质瘤或脑转移患者的术前和术后情况，研究了岛叶皮质在心脏内感受和识别面部表情情绪中的作用。尽管两个阶段之间的内感受准确性没有显着差异，但内感受准确性的变化与对愤怒和快乐表达的敏感性之间存在显着关联。术后阶段心跳计数任务的错误率增加与识别愤怒和快乐的准确性降低相关。由于大多数患者有左侧岛叶病变，因此将研究结果推广到右侧病变患者是未来的主题。据我们所知，这是第一项研究人类岛叶切除术后内感受和情绪变化的研究。研究结果表明，去除岛叶会通过内感受处理影响对愤怒和快乐等情绪的识别。(c) 2021 作者。由 Elsevier Ltd 出版。这是一篇遵循 CC BY-NC-ND 许可证 (http://creativecommons.org/licenses/by-nc-nd/4.0/) 的开放获取文章。
The insular cortex is considered an important region for feeling emotions through interoception. Most studies that report the role of the insula in integrating interoception and emotion have used neuroimaging techniques such as functional magnetic resonance imaging (fMRI); however, there are limited neuropsychological studies. The effects of insular lesions on emotion and interoception have not been suitably investigated. In this study, we examined the role of the insular cortex in cardiac interoception and recognizing emotions from facial expressions by comparing them pre-and post-operatively in patients with glial tumors or brain metastases associated with the insular lobe. Although no significant difference in interoceptive accuracy was observed between the two phases, there were significant associations between the changes in interoceptive accuracy and sensitivity to expressions of anger and happiness. An increased error rate in the heartbeat counting task in the post-operation phase was associated with a decreased accuracy in recognizing anger and happiness. Since most patients had left insula lesions, generalizability of the findings to patients with right lesions is a future subject. To the best of our knowledge, this is the first study to examine the change in interoception and emotion after insular resection in humans. The study results indicate that removal of the insula affects the recognition of emotions such as anger and happiness through interoceptive processing.(c) 2021 The Author(s).
