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: An exploratory analysis of the relationship between the brain's functional connectivity and intelligence scores derived from the Portuguese language version of the Wechsler Adult Intelligence Scale (WAIS-III) in a sample of 29 people, born and raised in Brazil found verbal comprehension was associated with global network efficiency, a new finding.

How feedback, motor imagery, and reward influence brain self-regulation using real-time fMRI.
Pradyumna Sepulveda,Ranganatha Sitaram,Mohit Rana,Cristian Montalba,Cristian Tejos,Sergio Ruiz,Sergio Ruiz +6 more
TL;DR: GF increased significantly their BOLD self‐regulation from day‐1 to day‐2 and GF,R showed the highest BOLD signal amplitude in SMA during the training, showing the varied influences of feedback, reward, and instructions on the brain.

TL;DR: Excessive connectivity within brain networks coupled to the DLPFC and MPFC, respectively, accompany cognitive deficits in persons at risk for schizophrenia, suggesting compensatory reactions in neural systems required for cognitive processing of attention and working memory tasks to brain changes associated with schizophrenia.

Intrinsic functional connectivity in late-life depression: trajectories over the course of pharmacotherapy in remitters and non-remitters

TL;DR: Functional connectivity changes differ depending on treatment response and can occur shortly after exposure to antidepressant medication, indicating that early changes in functional connectivity can occur after initial medication exposure.
Journal ArticleDOI
Thalamo-striato-cortical determinants to fatigue in multiple sclerosis.
TL;DR: The aim was to explore the thalamo‐striato‐cortical theory of central fatigue in multiple sclerosis patients with self‐reported fatigue and to expect altered brain activation in this network in MS participants while performing a complex cognitive task that challenged fatigue.

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.
Journal ArticleDOI
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.
