  • The Neural Basis of Interoception

    Terasawa Y., Brewer R., Interoception A Comprehensive Guide, 2024.01

    　View Summary

    The underlying neural substrates of interoception have been a topic of research interest from the conceptualisation of interoception. In fact, many of the (multiple) definitions of interoception have drawn upon our understanding of neural pathways and brain regions in order to distinguish interoception from other forms of perception, and discriminate between separate facets of interoception. In this chapter, we review early and contemporary research on the neural substrates of interoception. We describe the neural and humoral pathways from peripheral sensors in the body (chemoreceptors, humoral receptors, specialised mechanoreceptors and free nerve endings) to the brain, for example via cranial nerves and spinal visceral afferents projecting to the brainstem. We then summarise the limbic and cortical regions involved in interoception, such as the thalamus, anterior insula and anterior cingulate cortex. We also discuss recent evidence regarding the integration of interoeptive information, and interactions between afferent and efferent signals at different points throughout the interoceptive neural networks. We end the chapter with a discussion of outstanding questions and priorities for future research.

    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

    Terasawa Y., Motomura K., Natsume A., Iijima K., Chalise L., Sugiura J., Yamamoto H., Koyama K., Wakabayashi T., Umeda S.

    　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.

  • Altered interoceptive beliefs in alexithymia: Dissociating bias and precision using the heart rate discrimination task

    Acta Psychologica 270   107672 2026.10

    ISSN  00016918

    　View Summary

    Alexithymia has been widely associated with altered interoception, yet empirical findings remain inconsistent, partly because prior research has insufficiently examined the multidimensional components of interoception. This study aimed to provide a more comprehensive understanding of the relationship between alexithymia and interoception by independently examining the associations on interoceptive sensibility and interoceptive belief with alexithymia, while controlling for depression and trait anxiety. 86 undergraduate and graduate students completed questionnaires assessing alexithymia, interoceptive sensibility, depression, anxiety, and autistic traits. Interoceptive belief was measured using the Heart Rate Discrimination task, which provides psychophysical estimates of bias and precision in cardiac interoceptive judgements, alongside an exteroceptive condition. Results showed that alexithymia was selectively related to altered interoceptive belief. Difficulty describing feelings was associated with biased overestimation of cardiac activity, whereas externally oriented thinking was associated with reduced precision, indicating greater uncertainty in interoceptive belief. Path analysis further showed that reduced precision in interoceptive belief uniquely predicted externally oriented thinking, independent of depressive and anxiety symptoms. Interoceptive sensibility was evaluated using the Japanese version of the Multidimensional Assessment on Interoceptive Awareness. Results indicated that higher levels of alexithymia were associated with reduced adaptive interoceptive sensibility across multiple dimensions of bodily awareness. These findings suggest that while diminished interoceptive sensibility characterizes the subjective experience of alexithymia, altered interoceptive belief plays a more proximal role in its cognitive core, highlighting the importance of belief-based mechanisms in emotional inference.

    <p>本稿は，女性の月経周期に伴う感情変動のメカニズムを，身体内部の情報を知覚する「内受容感覚」という視点から検討することを目的とした．従来，月経前の黄体期における不安や抑うつ，易怒性といった精神症状は，性ホルモンの変動に伴う中枢および末梢の神経活動の変化と関連付けて考えられることが多かった．しかし，同一の生理的変化が生じていても症状の現れ方には著しい個人差がある．この個人差の要因として，身体の状態を知覚する内受容感覚の処理プロセスに着目した．女性50名を対象に，卵胞期と黄体期の2回にわたり，自律神経活動の測定，心拍カウント課題による内受容感覚の正確さの評価，および心理尺度（MAIA，STAI，PMDD評価尺度）を用いた調査を実施した．分析の結果，安静時の心拍数には周期による差は見られなかったものの，自身の身体に注意を向ける心拍カウント課題時において，黄体期は卵胞期よりも交感神経活動が有意に高まることが示された．心理的側面では，黄体期における状態不安の増大は，身体感覚と感情の関連性に敏感な傾向（MAIA―因子5：感情への気づき」）と強い正の相関を示した．さらに，卵胞期において心拍を正確に知覚できる個人ほど，PMDD症状を強く自覚していることが明らかとなった．以上の結果から，内受容感覚を通じた身体状態の受容・解釈プロセスが，月経に伴うネガティブ感情の変動の個人差に関与している可能性が示唆された．内受容感覚という視点の導入により，個々の女性が自身の身体信号をどのように受け止め，感情や思考と統合しているかを解明する鍵となることが期待される．</p>

    　View Summary

    我が国では気分障害の患者数が非常に多く，その原因となるメカニズム解明が求められている．実際，さまざまな療法では症状の改善が見られない「ノンリスポンダー」も一定数含まれる．その背景には，自律神経の応答性に個人差がある点，および自らの心臓の動きなどの自律神経活動の変化をどれだけ正確に感じ取ることができるかを示す指標である「内受容感覚」にも個人差がある点が関与している．また生活環境内には，気圧の変化など，自律神経活動を大きく作用する要因がある．そこで本研究では，気圧変化が気分変化とどのような関係にあるかについて，「心ー脳ー身体ー環境」の4者関係の複雑なメカニズム解明を通して明らかにする予定である．
    本研究は，精神疾患における気分のゆらぎと身体化の原因について，生活環境要因と心理的要因の効果を統合的に分析することを目的としている．気分の揺らぎはさまざまな原因によって起こる上に，身体化の背景には非常に複雑な要因が関わるため，身体生理機能・中枢神経機能に加え，主観的指標・客観的指標の両者を用いた心理的機能に着目する必要がある．今年度は，気圧の変化およびそれに対する内受容感覚に着目した実験を実施した．具体的には，身体化のなかでも慢性疼痛に深く関与されると考えられる気圧変化の影響について，健常者および身体症状症の症例を対象とした研究を実施した．特に，さまざまな部位に痛みが生じている患者に対して，複数の質問紙による主観報告を確認し，意思決定や感情処理のバイアスかあるか，痛み閾値に特殊性が見出されるか，痛みの感じ方に違いはあるか，などの側面について徹底的な解析を行い，さらに気圧変化時の自律神経動態について詳しく調べた．また自律神経に変化が生じていない状態および生じている状態における内受容感覚を詳細に調べ，主観・客観の両側面から多角的な実験データが取得できた．正確な感知が困難である気圧の変化に対する予測的反応性に着目し，自律神経の反応性をパターン別に分析し，それらの違いがどのような要因によって説明できるかを統合的に解析した．今後も，この実験と解析を継続し，総合的な観点から気分のゆらぎや痛みが生起されるメカニズムについて調べる．
    身体症状症研究については，当初，倫理審査審査に時間を要していたが，今年度は順調にリクルートが進み，順調なデータの取得ができている．臨床研究はさまざまな要因によって実験が計画通りに進まないことが多いが，本研究はその点では非常に順調に実験が進められており，データ解析も計画通りに進行している．このペースで次年度の研究も進める予定である．今後は対照となる健常者の実験も同時並行で進めることで，研究の遅れが出ないように工夫する．
    上述のとおり，本研究の遂行は順調であり，今後は患者群に加え，健常群対象の実験も同時並行で進める予定である．データが安定している部分については，積極的に学会での発表などを行い，専門家の意見を広く取り入れ，データの解釈に活かしていく予定である．

    　View Summary

    In this study, we analyzed how autonomic function is altered by insular gyrus removal. Furthermore, by directly stimulating the insular cortex during awake surgery, measuring ECG, heart rate and blood pressure changes, and performing a heartbeat detection task, the aim of this study was to elucidate the neural basis of autonomic functional activity in the insular cortex and establish a next-generation awake brain surgery method to identify autonomic function, preserve function and restore function over time.
    The performance of direct stimulation and heartbeat detection tasks, as well as their relationship to the surgical site, was investigated in a statistical analysis. Analysis is currently underway in 13 patients who were able to be enrolled, and it has been found that cardiac output tends to decrease as a result of the decrease in systolic blood pressure and increase in peripheral vascular resistance caused by insular stimulation.
