TLDR
The results suggest that brain activity during conscious REST is sustained by a large scale network of heteromodal associative parietal and frontal cortical areas, that can be further hierarchically organized in an episodic working memory parieto-frontal network, driven in part by emotions.About:

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.
Journal ArticleDOI
The precuneus: a review of its functional anatomy and behavioural correlates.
TL;DR: A useful conceptual framework is provided for matching the functional imaging findings with the specific role(s) played by this structure in the higher-order cognitive functions in which it has been implicated, and activation patterns appear to converge with anatomical and connectivity data in providing preliminary evidence for a functional subdivision within the precuneus.

TL;DR: Findings show that the baseline activity of the brain is consistent across subjects exhibiting significant temporal dynamics, with percentage BOLD signal change comparable with the signal changes found in task-related experiments.

Spatial registration and normalization of images
Karl J. Friston,John Ashburner,Chris D. Frith,Jean-Baptiste Poline,Jon D. Heather,Richard S. J. Frackowiak +5 more
TL;DR: A general technique that facilitates nonlinear spatial (stereotactic) normalization and image realignment is presented that minimizes the sum of squares between two images following non linear spatial deformations and transformations of the voxel (intensity) values.

Imaging Cognition II: An Empirical Review of 275 PET and fMRI Studies
Roberto Cabeza,Lars Nyberg +1 more
TL;DR: Analysis of regional activations across cognitive domains suggested that several brain regions, including the cerebellum, are engaged by a variety of cognitive challenges.

Emotion, Decision Making and the Orbitofrontal Cortex
TL;DR: The somatic marker hypothesis provides a systems-level neuroanatomical and cognitive framework for decisionMaking and the influence on it by emotion and the relationship between emotion, decision making and other cognitive functions of the frontal lobe, namely working memory is reviewed.

From sensation to cognition.
TL;DR: The destruction of transmodal epicentres causes global impairments such as multimodal anomia, neglect and amnesia, whereas their selective disconnection from relevant unimodal areas elicits modality-specific impairmentssuch as prosopagnosia, pure word blindness and category-specific anomias.
