    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.

  • Interoceptive training impacts the neural circuit of the anterior insula cortex

    Translational Psychiatry 14 ( 1 ) 206 2024.12

    　View Summary

    Interoception is the perception of afferent information that arises from anywhere and everywhere within the body. Recently, interoceptive accuracy could be enhanced by cognitive training. Given that the anterior insula cortex (AIC) is a key node of interoception, we hypothesized that resting functional connectivity (RSFC) from AIC was involved in an effect of interoceptive training. To address this issue, we conducted a longitudinal intervention study using interoceptive training and obtained RSFC using fMRI before and after the intervention. A heartbeat perception task evaluated interoceptive accuracy. Twenty-two healthy volunteers (15 females, age 19.9 ± 2.0 years) participated. After the intervention, interoceptive accuracy was enhanced, and anxiety levels and somatic symptoms were reduced. Also, RSFC from AIC to the dorsolateral prefrontal cortex (DLPFC), superior marginal gyrus (SMG), anterior cingulate cortex (ACC), and brain stem, including nucleus tractus solitarius (NTS) were enhanced, and those from AIC to the visual cortex (VC) were decreased according to enhanced interoceptive accuracy. The neural circuit of AIC, ACC, and NTS is involved in the bottom-up process of interoception. The neural circuit of AIC, DLPFC, and SMG is involved in the top-down process of interoception, which was thought to represent the cognitive control of emotion. The findings provided a better understanding of neural underpinnings of the effect of interoceptive training on somatic symptoms and anxiety levels by enhancing both bottom-up and top-down processes of interoception, which has a potential contribution to the structure of psychotherapies based on the neural mechanism of psychosomatics.

    <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>

  • Exploratory study of the relationship between predictive processing of the autonomic nervous system and symptoms of psychiatric disorders

    　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.
