How do you feel? Interoception: the sense of the physiological condition of the body.
TLDR
Functional anatomical work has detailed an afferent neural system in primates and in humans that represents all aspects of the physiological condition of the physical body that might provide a foundation for subjective feelings, emotion and self-awareness.Abstract:
As humans, we perceive feelings from our bodies that relate our state of well-being, our energy and stress levels, our mood and disposition. How do we have these feelings? What neural processes do they represent? Recent functional anatomical work has detailed an afferent neural system in primates and in humans that represents all aspects of the physiological condition of the physical body. This system constitutes a representation of 'the material me', and might provide a foundation for subjective feelings, emotion and self-awareness.read more

Interoceptive awareness in experienced meditators
Sahib S. Khalsa,David Rudrauf,Antonio R. Damasio,Richard J. Davidson,Antoine Lutz,Daniel Tranel +5 more
TL;DR: Compared to nonmeditators, meditators consistently rated their interoceptive performance as superior and the difficulty of the task as easier, which provides evidence against the notion that practicing attention to internal body sensations, a core feature of meditation, enhances the ability to sense the heartbeat at rest.

Altered Amygdala Resting-State Functional Connectivity in Post-Traumatic Stress Disorder
Christine A. Rabinak,Mike Angstadt,Robert C. Welsh,Amy E. Kenndy,Mark Lyubkin,Brian Martis,K. Luan Phan +6 more
TL;DR: These findings suggest that the aberrant amygdala and insula activation to fear-evocative probes previously characterized in PTSD may be driven by an underlying enhanced connectivity between the amygdala, a region known for perceiving threat and generating fear responses, and the insula, a area known for processing the meaning and prediction of aversive bodily states.

Descending modulation of pain: the GABA disinhibition hypothesis of analgesia.
TL;DR: Within the central nervous system, descending systems exist to endogenously modulate the authors' perception of pain and a descending PAG-RVM system forms the circuitry that underlies the physiological phenomenon of stress-induced analgesia (SIA).

Moral judgments recruit domain-general valuation mechanisms to integrate representations of probability and magnitude.
Amitai Shenhav,Joshua D. Greene +1 more
TL;DR: The present results suggest that complex life-and-death moral decisions that affect others depend on neural circuitry adapted for more basic, self-interested decision making involving material rewards.

Uncertainty during Anticipation Modulates Neural Responses to Aversion in Human Insula and Amygdala
Issidoros Sarinopoulos,Daniel W. Grupe,Kristen L. Mackiewicz,John D. Herrington,M. Lor,E. E. Steege,Jack B. Nitschke +6 more
TL;DR: Using functional magnetic resonance imaging, it is found that uncertainty-related expectations modulated neural responses to aversion and highlight the temporal dynamics of ACC, insula, and amygdala recruitment for processing aversion in the context of uncertainty.

The Principles of Psychology
TL;DR: For instance, the authors discusses the multiplicity of the consciousness of self in the form of the stream of thought and the perception of space in the human brain, which is the basis for our work.

Descartes' Error: Emotion, Reason, and the Human Brain
TL;DR: The authors argued that rational decisions are not the product of logic alone - they require the support of emotion and feeling, drawing on his experience with neurological patients affected with brain damage, Dr Damasio showed how absence of emotions and feelings can break down rationality.
