Interoception can be broadly defined as the sense of signals originating within the body. As such, interoception is critical for our sense of embodiment, motivation, and well-being. And yet, despite its importance, interoception remains poorly understood within modern science. This paper reviews interdisciplinary perspectives on interoception, with the goal of presenting a unified perspective from diverse fields such as neuroscience, clinical practice, and contemplative studies. It is hoped that this integrative effort will advance our understanding of how interoception determines well-being, (...) and identify the central challenges to such understanding. To this end, we introduce an expanded taxonomy of interoceptive processes, arguing that many of these processes can be understood through an emerging predictive coding model for mind–body integration. The model, which describes the tension between expected and felt body sensation, parallels contemplative theories, and implicates interoception in a variety of affective and psychosomatic disorders. We conclude that maladaptive construal of bodily sensations may lie at the heart of many contemporary maladies, and that contemplative practices may attenuate these interpretative biases, restoring a person’s sense of presence and agency in the world.

The Buddhist technical term was first translated as ‘mindfulness’ by T.W. Rhys Davids in 1881. Since then various authors, including Rhys Davids, have attempted definitions of what precisely is meant by mindfulness. Initially these were based on readings and interpretations of ancient Buddhist texts. Beginning in the 1950s some definitions of mindfulness became more informed by the actual practice of meditation. In particular, Nyanaponika's definition appears to have had significant influence on the definition of mindfulness adopted by those who developed (...) MBSR and MBCT. Turning to the various aspects of mindfulness brought out in traditional Theravāda definitions, several of those highlighted are not initially apparent in the definitions current in the context of MBSR and MBCT. Moreover, the MBSR and MBCT notion of mindfulness as ‘non-judgmental’ needs careful consideration from a traditional Buddhist perspective. Nevertheless, the difference in emphasis apparent in the theoretical definitions of mindfulness may not be so significant in the actual clinical application of mindfulness techniques. (shrink)

The Bayesian brain hypothesis provides an attractive unifying framework for perception, cognition, and action. We argue that the framework can also usefully integrate interoception, the sense of the internal physiological condition of the body. Our model of entails a new view of emotion as interoceptive inference and may account for a range of psychiatric disorders of selfhood.
