    Scope: The impact of interoception on memory

     View Summary

    <p>Using interoception as a keyword, this chapter has summarized how changes in the internal physical state are encoded and how the processing of interoceptive information affects the memory of episodes and events. Interoceptive information processing is discussed frequently in the context of emotion in psychology. On the other hand, research studies and literature that have examined its relation to episodic memory are rare. However, changes in the internal physical state exist at the foundation of various concepts that have examined its relationship with memory. To understand the relationship more precisely, we focused on the following issues in this chapter: emotional arousal and bodily responses; effects of bodily responses on memory encoding; judgment related to memories and bodily response; and insular cortex and memory consolidation. Throughout the chapter, we presented the possibility that change in the physical state itself plays a role in latently supporting the encoding and recollection process.</p>

  • Paradoxical somatic information processing for interoception and anxiety in alexithymia

    Yuri Terasawa, Kentaro Oba, Yuki Motomura, Ruri Katsunuma, Hiroki Murakami, Yoshiya Moriguchi

    European Journal of Neuroscience (Wiley)  54 ( 11 ) 8052 - 8068 2021.11

    Research paper (scientific journal), Joint Work, Accepted,  ISSN  0953816X

     View Summary

    The concept of alexithymia has garnered much attention in an attempt to understand the psychological mechanisms underlying the experience of feeling an emotion. In this study, we aimed to understand how the interoceptive processing in an emotional context relates to problems of alexithymia in recognizing self-emotions. Therefore, we prepared experimental conditions to induce emotional awareness based on interoceptive information. As such, we asked participants to be aware of interoception under an anxiety-generating situation anticipating pain, having them evaluate their subjective anxiety levels in this context. High alexithymia participants showed attenuated functional connectivity within their ‘interoception network’, particularly between the insula and the somatosensory areas when they focused on interoception. In contrast, they had enhanced functional connectivity between these regions when they focused on their anxiety about pain. Although access to somatic information is supposed to be more strongly activated while attending to interoception in the context of primary sensory processing, high alexithymia individuals were biased as this process was activated when they felt emotions, suggesting they recognize primitive and unprocessed bodily sensations as emotions. The paradoxical somatic information processing may reflect their brain function pathology for feeling emotions and their difficulty with context-dependent emotional control.

  • Effects of insular resection on interactions between cardiac interoception and emotion recognition

     View Summary

    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.

    <p>Interoception is sensation for the internal state of the body. Changes in the internal state of the body, such as the activity of internal organs and associated sensations and pain, are the instances of this sensation. It has been rapidly recognized over the past two decades and has come to attract attention as one of the elements underlying various mental functions. This paper outlines the definition of interoception, the systems of manifestation and dynamic regulation of interoception, the neural basis of interoception and methods of assessment.</p>

  • Effect of subconscious changes in bodily response on thought shifting in people with accurate interoception

    Scientific Reports (Scientific Reports)  13 ( 1 ) 16651 2023.12

     View Summary

    Our thought states shift from one state to another from moment to moment. The relationship between the thought shifting and bodily responses is yet to be directly examined. This exploratory study examined the influence of cardiovascular reactivity and interoception—sensing an internal bodily state—on the shifting of thought states. Participants (N = 100, 70 women) completed two tasks: the heartbeat counting task (HCT) and the vigilance task (VT). We assessed their interoceptive accuracy through their performance on the HCT. The VT was a simple sustained attention task in which participants pressed a key when the target stimulus appeared and were asked to report their thoughts. We presented subliminal vibration stimuli to induce alterations in heart rate (i.e., vibration block). Results showed that participants with higher interoceptive accuracy reported more continuation of self-referential thought (about past episodes and future plans regarding themselves) during the vibration block than did those with lower interoceptive accuracy. These results suggest that individuals with higher interoceptive accuracy are more likely to be influenced by their subliminal bodily response, resulting in divergent attention from the task and intermittent self-referential thought.

     View Summary

    Interoception, the sense of the internal state of the body, plays an important role in anxiety disorders and other psychiatric disorders, as well as in neurological disorders that cause pain. This effect is likely to occur in situations where anticipatory processing is possible. However, the mechanisms behind these phenomena remain unresolved. We first conducted a study to develop an accurate autonomic index and showed that facial skin blood flow could be an appropriate marker to reflect the fine state of mind. The results of this study may be applied to the treatment of blushing disorder or other anxiety-related disorders. The results of other experiment for the patients with chronic cephalalgia showed that the interoceptive accuracy tended to be lower in the patients, suggesting that it relates to the intensity of pain felt, not the frequency of pain.

  • The effects of menstrual cycle and interoception on emotion recognition and regulation


    MEXT,JSPS, Grant-in-Aid for Scientific Research, Terasawa Yuri, Grant-in-Aid for Scientific Research (C), Principal investigator

     View Summary

    Emotions arise from an integrated understanding of interoception and environmental information. However, this process in the brain has not been fully elucidated. In this study, we focused on fluctuations in autonomic nervous system activity during the female menstrual cycle as an example of how changes in internal body states affect emotions in daily life. One participant was asked to participate in the experiment during the follicular and luteal phases, and data were collected for 34 participants. In each experiment, we assessed interoception, autonomic responses, and emotion recognition tendencies. In addition, fMRI imaging was performed at rest and during task performance. Participants who understood the connection between the body and emotions were shown to be potentially more sensitive to changes in their physical physiological state due to fluctuations in their menstrual cycle.
