[Perspective on Emotion from Allostasis Mediated by Interoception].

Feeling emotional responses, such as heartbeat and respiration, influence subjective feeling of emotion. The role of interoception as a link in this relationship has been the focus of much attention. The predictive coding model is suggested for understanding the mechanism of interoception, and the model is also closely related to allostasis. This paper introduces a perspective on emotion from the allostasis mediated by interoception.
