Abstract:

Interoception, a process wherein the nervous system senses, interprets, and integrates signals originating from within the body to provide a moment-by-moment mapping of the body’s internal state across conscious and unconscious levels, is crucial for maintaining homeostasis. The interoceptive system exhibits a unique rhythm, and the disruption of this rhythm is a prominent feature of different mental disorders. Therefore, the role of interoception in mental health has gained increased attention from researchers. In this paper, we review the physiological and psychological mechanisms of interoceptive rhythm, and then summarize the empirical evidence on the interaction between interoceptive rhythm and mental health. Finally, we propose an integrative theory grounded in the free energy framework and predictive coding model, which provides a testable framework to quantify the potential mechanism through which interoceptive rhythm affects mental health.

摘要：

内感受是神经系统感觉、解释、整合来自身体内部的信号，从而在意识和无意识层面上提供关于身体内部实时映射的加工过程，在维持内稳态中扮演着关键角色。内感受系统展现出特有的节律性，内感受节律失常是多种精神障碍的显著特征，因此内感受在心理健康中的作用受到越来越多研究者的关注。本文首先阐述内感受节律的生理和心理机制，进而回顾内感受节律与心理健康相互影响的实证研究进展，最后在总结经典理论和理论发展的基础上，提出一个基于自由能量框架和预测编码模型的整合理论，该理论能够解释内感受节律影响心理健康的潜在机制，从而为回答内感受节律在维持内外稳态平衡和心理健康中的作用提供可检验的理论框架。
