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

Sensitive Period for Cognitive Repurposing of Human Visual Cortex.
TL;DR: Comparing visual cortex function in individuals who lost their vision as adults (after age 17) to congenitally blind and sighted blindfolded adults shows cognitive repurposing of human cortex is limited by sensitive periods.
Journal ArticleDOI
Distinct Frontoparietal Networks Underlying Attentional Effort and Cognitive Control
TL;DR: Resting frontoparietal connectivity predicts performance on attention tasks that rely on cognitive control networks and that, under challenging conditions, other control regions dynamically couple with this network to initiate the engagement of cognitive control.
Journal ArticleDOI
From Synchrony to Asynchrony: Cerebellar-Basal Ganglia Functional Circuits in Young and Older Adults.
TL;DR: A shift in connectivity was found, from one of synchrony in YA, to asynchrony in OA, resulting in substantial age differences, and this findings significantly advance the understanding of cerebellar-basal ganglia interactions in the human brain.
Journal ArticleDOI
Attention to number: The convergence of numerical magnitude processing, attention, and mathematics in the inferior frontal gyrus.
Eric D. Wilkey,Gavin R. Price +1 more
TL;DR: There is a need to reframe existing models of the relation between number processing and math competence to include the interaction between attention and use of numerical information, or in other words “attention to number.”

Decreased Connectivity and Increased Blood Oxygenation Level Dependent Complexity in the Default Mode Network in Individuals with Chronic Fatigue Syndrome.
Zack Shan,Kevin Finegan,Sandeep Bhuta,Timothy Ireland,Donald Staines,Sonya Marshall-Gradisnik,Leighton R. Barnden +6 more
TL;DR: Activity in the default mode network (DMN) is more complex and less coordinated in CFS, suggesting brain network analysis could be potentially used as a diagnostic biomarker for CFS.

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.
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.
