Background: Interoceptive signals related to changes in heartbeat, respiration, and gastric functioning continuously feedback to the brain. The interpretation of these signals influences several cognitive, affective, and motoric functions. Previous research has highlighted the distinction between the ability to accurately detect interoceptive information (i.e., interoceptive accuracy) and an individual's beliefs about his or her interoceptive abilities (i.e., interoceptive sensibility). Although numerous studies have delineated the neural substrates of interoceptive accuracy, less is known about the brain areas involved with interoceptive sensibility.

功能连接性与内感受性之间的关系

背景：与心跳、呼吸和胃功能变化相关的内感受信号不断反馈到大脑。这些信号的解释会影响一些认知、情感和运动功能。以前的研究强调了准确检测内感受信息的能力（即内感受准确性）和个人对其内感受能力的信念（即内感受敏感性）之间的区别。尽管许多研究已经描述了内感受准确性的神经基础，但对内感受敏感性所涉及的大脑区域知之甚少。
