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

DPABI: Data Processing & Analysis for (Resting-State) Brain Imaging.
TL;DR: The newly developed toolbox, DPABI, which was evolved from REST and DPARSF is introduced, designed to make data analysis require fewer manual operations, be less time-consuming, have a lower skill requirement, a smaller risk of inadvertent mistakes, and be more comparable across studies.
Journal ArticleDOI
Anticorrelations in resting state networks without global signal regression
TL;DR: The results suggest that anticor Relations observed in resting-state connectivity are not an artifact introduced by global signal regression and might have biological origins, and that the CompCor method can be used to examine valid anticorrelations during rest.

GRETNA: a graph theoretical network analysis toolbox for imaging connectomics
Jinhui Wang,Jinhui Wang,Xindi Wang,Mingrui Xia,Xuhong Liao,Alan C. Evans,Yong-Min He,Yong-Min He +7 more
TL;DR: It is demonstrated that human brain functional networks exhibit efficient small-world, assortative, hierarchical and modular organizations and possess highly connected hubs and that these findings are robust against different analytical strategies.

Robust prediction of individual creative ability from brain functional connectivity
Roger E. Beaty,Yoed N. Kenett,Alexander P. Christensen,Monica D. Rosenberg,Mathias Benedek,Qunlin Chen,Andreas Fink,Jiang Qiu,Thomas R. Kwapil,Michael J. Kane,Paul J. Silvia +10 more
TL;DR: A whole-brain network associated with high-creative ability comprised of cortical hubs within default, salience, and executive systems—intrinsic functional networks that tend to work in opposition is identified, suggesting that highly creative people are characterized by the ability to simultaneously engage these large-scale brain networks.

Resting-state networks link invasive and noninvasive brain stimulation across diverse psychiatric and neurological diseases.

TL;DR: It is found that although different types of brain stimulation are applied in different locations, targets used to treat the same disease most often are nodes within the same brain network as defined by resting-state functional-connectivity MRI.

Persistent default-mode network connectivity during light sedation.
Michael D. Greicius,Vesa Kiviniemi,Osmo Tervonen,Vilho Vainionpää,Seppo Alahuhta,Allan L. Reiss,Vinod Menon +6 more
TL;DR: A direct comparison found that there was significantly reduced functional connectivity in the posterior cingulate cortex during conscious sedation, confirming that low‐frequency oscillations in the DMN persist and remain highly correlated even at reduced levels of consciousness.

Effects of model-based physiological noise correction on default mode network anti-correlations and correlations
Catie Chang,Gary H. Glover +1 more
TL;DR: It was observed that the low-frequency respiratory volume and cardiac rate regressors used within the physiological noise correction algorithm displayed significant (but not total) shared variance with the global signal, and constitute a model-based alternative to correcting for non-neural global noise.
Journal ArticleDOI
Undirected graphs of frequency-dependent functional connectivity in whole brain networks
TL;DR: The partial coherency spectrum between a pair of human brain regional fMRI time-series depends on the anatomical distance between regions: long-distance edges represent conditional dependence between bilaterally symmetric neocortical regions and between regions of prefrontal and parietal association cortex in the same hemisphere, are predominantly subtended by low-frequency components.

Dissociable Connectivity within Human Angular Gyrus and Intraparietal Sulcus: Evidence from Functional and Structural Connectivity
Lucina Q. Uddin,Kaustubh Supekar,Hitha Amin,Elena Rykhlevskaia,Daniel A. Nguyen,Michael D. Greicius,Vinod Menon +6 more
TL;DR: Functional and structural connectivity analyses provide evidence for functional heterogeneity of cytoarchitectonically defined subdivisions within IPL and offer a novel framework for synthesis and interpretation of the task-related activations and deactivations involving the IPL during cognition.

Alterations of resting state functional connectivity in the default network in adolescents with autism spectrum disorders
Shih Jen Weng,Jillian Lee Wiggins,Scott Peltier,Melisa Carrasco,Susan Risi,Catherine Lord,Christopher S. Monk +6 more
TL;DR: The findings indicate that adolescents with ASD show weaker connectivity in the default network than previously reported in adults with ASD, and shows that weaker connectivity within thedefault network is associated with specific impairments in ASD.
