  journal={Nature Reviews Neuroscience},
Feelings are mental experiences of body states. They signify physiological need (for example, hunger), tissue injury (for example, pain), optimal function (for example, well-being), threats to the organism (for example, fear or anger) or specific social interactions (for example, compassion, gratitude or love). Feelings constitute a crucial component of the mechanisms of life regulation, from simple to complex. Their neural substrates can be found at all levels of the nervous system, from… 
Neurobiology of emotions: an update
An updated discussion about the neurobiology of processes relating to emotions is presented, focusing on the main neural structures that relate to emotions, the paths and circuits of greater relevance, and the implicated neurotransmitters and connections that possess neurovegetative control.

The atypical traits of the INS and the direct interactions between neural and non‐neural physiological compartments of the organism, neither of which is present in exteroceptive systems, plausibly explain the qualitative and subjective aspects of feelings, thus accounting for their conscious nature.
The Brain Stress Systems II: The Mind Level of Brain Operations
These mind-level operations affect all of those other processes in a top-down manner and can alter feelings of body state in powerful ways that incline the child either toward health and well-being or toward ill health and dis-ease.
Neural correlates of fear: insights from neuroimaging
The stereotyped expression of fear can thus be viewed as a special construc- tion from combinations of these processes, and an important motivator for understanding neural fear mechanisms is the debilitating clinical expression of anxiety.

Psychological Conflict and Physical Illness: A New Mind–Body Model
As organisms, human beings are integrations of matter, energy, and information. The present article offers a new vision regarding the nature of emotions and their influence on the physical body.

The Neuropsychology of Emotion and Emotion Regulation: The Role of Laterality and Hierarchy
It is proposed that, because emotion-regulation strategies are complex higher-order cognitive processes, the question appears to be not the lateralization of the entire emotional process, but the lateralized of the specific cognitive tools the authors use to manage their feelings, in a range of different ways.
Expressions of emotions across species


The Embodiment of Emotional Feelings in the Brain
It is shown that experience of core and body–boundary–violation disgust are dissociable in both peripheral autonomic and central neural responses and also that emotional experience specific to anterior insular activity encodes these different underlying patterns of peripheral physiological responses.
Neural basis of emotions
In modern neurobiological terms, emotions are complex programs of actions triggered by the presence of certain stimuli, external to the body or from within the body, when such stimuli activate
Subcortical and cortical brain activity during the feeling of self-generated emotions
The hypothesis that the process of feeling emotions requires the participation of brain regions that are involved in the mapping and/or regulation of internal organism states is tested, indicating the close relationship between emotion and homeostasis.

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.
Neural correlates of admiration and compassion
The study revealed a previously undescribed pattern within the posteromedial cortices (the ensemble of precuneus, posterior cingulate cortex, and retrosplenial region), an intriguing territory currently known for its involvement in the default mode of brain operation and in self-related/consciousness processes.
Persistence of feelings and sentience after bilateral damage of the insula.
This study investigates the proposal that the neural substrate of feeling states is to be found first subcortically and then secondarily repeated at cortical level in a patient whose insular cortices were destroyed bilaterally as a result of Herpes simplex encephalitis.
