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

Dissociable Intrinsic Connectivity Networks for Salience Processing and Executive Control
William W. Seeley,Vinod Menon,Alan F. Schatzberg,Jennifer Keller,Gary H. Glover,Heather A. Kenna,Allan L. Reiss,Michael D. Greicius +7 more
TL;DR: Two distinct networks typically coactivated during functional MRI tasks are identified, anchored by dorsal anterior cingulate and orbital frontoinsular cortices with robust connectivity to subcortical and limbic structures, and an “executive-control network” that links dorsolateral frontal and parietal neocortices.
Journal ArticleDOI
From inflammation to sickness and depression: when the immune system subjugates the brain
TL;DR: In response to a peripheral infection, innate immune cells produce pro-inflammatory cytokines that act on the brain to cause sickness behaviour, which can lead to an exacerbation of sickness and the development of symptoms of depression in vulnerable individuals.
Journal ArticleDOI
How do you feel--now? The anterior insula and human awareness.
TL;DR: New findings suggest a fundamental role for the AIC (and the von Economo neurons it contains) in awareness, and thus it needs to be considered as a potential neural correlate of consciousness.

Saliency, switching, attention and control: a network model of insula function
Vinod Menon,Lucina Q. Uddin +1 more
TL;DR: It is suggested that this framework provides a parsimonious account of insula function in neurotypical adults, and may provide novel insights into the neural basis of disorders of affective and social cognition.
Journal ArticleDOI
Meeting of minds: the medial frontal cortex and social cognition.
David M. Amodio,Chris D. Frith +1 more
TL;DR: This work reviews the emerging literature that relates social cognition to the medial frontal cortex and proposes a theoretical model of medial frontal cortical function relevant to different aspects of social cognitive processing.

fMRI of thermal pain: effects of stimulus laterality and attention.
TL;DR: Brain activity was studied by fMRI in 18 healthy subjects during stimulation of the thenar eminence of the hand with either warm (non-painful, 40 degrees C) or hot (painful) stimuli using a contact thermode to discuss the role of the insula in thermosensation and attention.

Forebrain mechanisms of nociception and pain: analysis through imaging.
TL;DR: An animal model for investigating stimulus-induced rCBF responses in the rat is developed and it is shown that there is a progressive and selective activation of somatosensory and limbic system structures in the brain and brainstem following the subcutaneous injection of formalin.
Book ChapterDOI
The emotional motor system.
TL;DR: This survey gives an overview of the pathways belonging to the so-called emotional motor system or the third motor system as defined by Holstege, and the similarities and differences with the core, median and lateral paracore areas of the CNS asdefined by Nieuwenhuys.

TL;DR: In this article, the authors explored the central neural structures underlying perception of dyspnea in healthy subjects by restraining ventilation below spontaneous levels while holding arterial oxygen and carbon dioxide levels constant.
