| Abstract | The insular cortex is considered as a key region for the feeling emotion through interoception. Most studies reporting on the role of the insular cortex in the integration of interoception and emotion have used neuroimaging methods, but neuropsychological studies are limited. In the present study, we investigated the role of the insular cortex in emotion recognition in patients with tumors associated with the insular cortex by performing the heartbeat-counting and the facial expression recognition tasks before and after surgical resection. The results showed a significant association between changes in performance on the heartbeat-counting task before and after surgery and changes in sensitivity to angry and happy facial expressions. The results of this study indicate that resection of the insular region affects the recognition of emotions such as anger and happiness through interoception. |
