自我被认为是建立在内感受加工的基础上的，心跳诱发的皮层活动是这一加工的神经生理标志。然而，关于心跳诱发的皮层反应与自我加工（包括外感受性和心理自我加工）之间的关系，研究结果并不一致。在这篇综述中，我们回顾了先前关于自我加工和心跳诱发的皮层反应之间关系的研究，并强调了不同的时空特征和涉及的大脑区域。我们认为，大脑状态传递了自我处理和心跳诱发的皮层反应之间的相互作用，从而解释了这种不一致。大脑状态是一种自发的大脑活动，它以一种非随机的方式高度和持续地变化，是大脑功能的基础，被提出为极高维度空间中的一个点。为了阐明我们的假设，我们回顾了大脑状态维度与自我加工和心跳诱发的皮层反应之间的相互作用。这些相互作用表明，自我加工和心跳诱发的皮层反应通过大脑状态进行中继。最后，我们讨论了研究大脑状态是否以及如何影响自我-心脏相互作用的可能方法。
The self has been proposed to be grounded in interoceptive processing, with heartbeat-evoked cortical activity as a neurophysiological marker of this processing. However, inconsistent findings have been reported on the relationship between heartbeat-evoked cortical responses and self-processing (including exteroceptive- and mental-self-processing). In this review, we examine previous research on the association between self-processing and heartbeat-evoked cortical responses and highlight the divergent temporal-spatial characteristics and brain regions involved. We propose that the brain state relays the interaction between self-processing and heartbeat-evoked cortical responses and thus accounts for the inconsistency. The brain state, spontaneous brain activity which highly and continuously changes in a nonrandom way, serves as the foundation upon which the brain functions and was proposed as a point in an extremely high-dimensional space. To elucidate our assumption, we provide reviews on the interactions between dimensions of brain state with both self-processing and heartbeat-evoked cortical responses. These interactions suggest the relay of self-processing and heartbeat-evoked cortical responses by brain state. Finally, we discuss possible approaches to investigate whether and how the brain state impacts the self-heart interaction.
