Conn: A Functional Connectivity Toolbox for Correlated and Anticorrelated Brain Networks
TLDR
The results indicate that the CompCor method increases the sensitivity and selectivity of fcMRI analysis, and show a high degree of interscan reliability for many fc MRI measures.Citations

TL;DR: It is suggested that unique brain-based abnormalities differentiate individuals with PTSD from TEHCs, differentiate individualsWith PTSD from those with PTSD+MDD, and demonstrate clinical utility in predicting levels of symptomatology and treatment response.

Neural correlates of working memory training: Evidence for plasticity in older adults.
Alexandru D. Iordan,Katherine A. Cooke,Kyle D. Moored,Benjamin Katz,Martin Buschkuehl,Susanne M. Jaeggi,Thad A. Polk,Scott Peltier,John Jonides,Patricia A. Reuter-Lorenz +9 more
TL;DR: Training increased task-related functional connectivity in older adults, both within the WM network and between this task-positive network and the task-negative/default-mode network.

The effect of distress on the balance between goal-directed and habit networks in obsessive-compulsive disorder.
Anouk van der Straten,Wieke van Leeuwen,Damiaan Denys,Hein J. F. van Marle,Hein J. F. van Marle,Guido van Wingen +5 more
TL;DR: Compulsivity in OCD is associated with altered connectivity between the goal-directed and default mode networks during psychological distress, which is positively correlated with compulsivity but not obsession severity.
Journal ArticleDOI
Pre-treatment graph measures of a functional semantic network are associated with naming therapy outcomes in chronic aphasia.
TL;DR: There is a meaningful and possibly prognostically-informative relationship between patients' functional network properties and their response to naming therapy, and group differences in local measures were identified in several regions associated with a variety of cognitive functions.
Journal ArticleDOI
Small Changes, But Huge Impact? The Right Anterior Insula's Loss of Connection Strength during the Transition of Old to Very Old Age.
TL;DR: It is shown that age-related changes in the intrinsically active functional architecture of the brain in the study group covering an age range from 65 to 85 years have the potential to impair older adult's performance of working memory tasks.

Collective dynamics of small-world networks
TL;DR: Simple models of networks that can be tuned through this middle ground: regular networks ‘rewired’ to introduce increasing amounts of disorder are explored, finding that these systems can be highly clustered, like regular lattices, yet have small characteristic path lengths, like random graphs.

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.

Complex brain networks: graph theoretical analysis of structural and functional systems
Edward T. Bullmore,Olaf Sporns +1 more
TL;DR: This article reviews studies investigating complex brain networks in diverse experimental modalities and provides an accessible introduction to the basic principles of graph theory and highlights the technical challenges and key questions to be addressed by future developments in this rapidly moving field.
Journal ArticleDOI
Functional connectivity in the motor cortex of resting human brain using echo-planar MRI.
TL;DR: It is concluded that correlation of low frequency fluctuations, which may arise from fluctuations in blood oxygenation or flow, is a manifestation of functional connectivity of the brain.

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.
