Although the role of the insular cortex in representing bodily and emotional feelings has been recognized, whether the mid-posterior and anterior parts of the insula act differentially in the encoding and regulation of emotional feelings is still unclear. In this functional magnetic resonance imaging (fMRI) study, we examined the effects of the creative cognitive reappraisals versus the non-creative ordinary reappraisals on the activation pattern of the mid-posterior and anterior insular cortex during the processing of unpleasant pictures by comparing the neural correlates for processing these pictures before and after the application of cognitive reappraisals. We found significant anterior insular activation after the application of cognitive reappraisals, especially the creative ones, in contrast to the significant mid-posterior insular activation before the application of the cognitive reappraisals or after the application of the non-creative ordinary reappraisals. This finding supports the posterior-to-anterior progression hypothesis with the mid-posterior insular cortex being used for the encoding of primary emotional feelings and the anterior insular cortex being used for the encoding of regulated or modulated emotional feelings.
尽管岛叶皮质在表征身体感觉和情感方面的作用已得到认可，但岛叶中后部和前部在情感的编码与调节中是否发挥不同作用仍不清楚。在这项功能磁共振成像（fMRI）研究中，我们通过比较认知重评前后处理不愉快图片的神经关联，研究了创造性认知重评与非创造性普通重评对处理不愉快图片过程中岛叶中后部和前部皮质激活模式的影响。我们发现，应用认知重评后，尤其是创造性重评后，岛叶前部有显著激活，这与应用认知重评前或应用非创造性普通重评后岛叶中后部的显著激活形成对比。这一发现支持了从后向前发展的假说，即岛叶中后部皮质用于编码原始情感，而岛叶前部皮质用于编码经过调节或调制的情感。
