How is our self related to midline regions and the default-mode network?
Pengmin Qin,Georg Northoff +1 more
TLDR
The data suggest that the sense of self may result from a specific kind of interaction between resting state activity and stimulus-induced activity, i.e., rest-stimulus interaction, within the midline regions.Citations

Analysis of Brain Activity Using fMRI Data for Affective Evaluation of the Self and Others
TL;DR: In this paper, subjects were presented with adjectives describing positive, neutral, or negative characteristics and were asked to assess the extent to which these characteristics applied to the subject him or herself, or to a friend, a stranger, or an unpleasant person.
Journal ArticleDOI
The thickness of the ventral medial prefrontal cortex predicts the prior-entry effect for allocentric representation in near space
TL;DR: In this paper , a shape-label matching task was adopted to establish an SPE, combined with a spatial reference frame judgment task, to examine how the self-prioritization effect leads to preferential processing of near-space or egocentric representations.
Journal ArticleDOI
Seeing oneself through the eyes of another: A look at psychedelic insight
TL;DR: In this paper , a young man who was destroying his life with alcohol had a remarkable, unexpected change in perspective after drinking Robitussin in desperation, in which he felt he could see himself "objectively, from a third-party perspective".
Journal ArticleDOI
Self-evaluation of social-rank in socially anxious individuals associates with enhanced striatal reward function
TL;DR: For instance, this paper found that self-evaluation of high-power in social anxiety involves excessive striatal reward-related activation, and pinpointed the downregulation of VS-VMPFC activity within such selfevaluative context as a potential neural outcome for therapeutic interventions.
Journal ArticleDOI
Neural signal variability relates to maladaptive rumination in depression
TL;DR: In this article , the authors examined differences in BOLD signal variability (BOLDSD) related to rumination subtypes for the following regions of interest previously implicated in rumination: amygdala, medial prefrontal, anterior cingulate, posterior cingulated, and dorsolateral prefrontal cortices (dlPFC).

A default mode of brain function.
Marcus E. Raichle,Ann Mary MacLeod,Abraham Z. Snyder,William J. Powers,Debra A. Gusnard,Gordon L. Shulman +5 more
TL;DR: A baseline state of the normal adult human brain in terms of the brain oxygen extraction fraction or OEF is identified, suggesting the existence of an organized, baseline default mode of brain function that is suspended during specific goal-directed behaviors.
Journal ArticleDOI
AFNI: software for analysis and visualization of functional magnetic resonance neuroimages
TL;DR: A package of computer programs for analysis and visualization of three-dimensional human brain functional magnetic resonance imaging (FMRI) results is described and techniques for automatically generating transformed functional data sets from manually labeled anatomical data sets are described.
Journal ArticleDOI
The Brain's Default Network Anatomy, Function, and Relevance to Disease
TL;DR: Past observations are synthesized to provide strong evidence that the default network is a specific, anatomically defined brain system preferentially active when individuals are not focused on the external environment, and for understanding mental disorders including autism, schizophrenia, and Alzheimer's disease.

The human brain is intrinsically organized into dynamic, anticorrelated functional networks
Michael D. Fox,Abraham Z. Snyder,Justin L. Vincent,Maurizio Corbetta,David C. Van Essen,Marcus E. Raichle +5 more
TL;DR: It is suggested that both task-driven neuronal responses and behavior are reflections of this dynamic, ongoing, functional organization of the brain, featuring the presence of anticorrelated networks in the absence of overt task performance.

Functional connectivity in the resting brain: A network analysis of the default mode hypothesis
TL;DR: This study constitutes, to the knowledge, the first resting-state connectivity analysis of the default mode and provides the most compelling evidence to date for the existence of a cohesive default mode network.
