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

Impaired insight into illness and cognitive insight in schizophrenia spectrum disorders: Resting state functional connectivity
Philip Gerretsen,Mahesh Menon,David C. Mamo,Gagan Fervaha,Gary Remington,Bruce G. Pollock,Ariel Graff-Guerrero +6 more
TL;DR: Increased connectivity in DMN and SRN with the left angular gyrus and insula may represent neural correlates of impaired clinical insight in schizophrenia spectrum disorders, and is consistent with the literature attributing impaired insight to left hemisphere dominance.
Journal ArticleDOI
Primate homologs of mouse cortico-striatal circuits
Joshua H. Balsters,Joshua H. Balsters,Valerio Zerbi,Jerome Sallet,Nicole Wenderoth,Rogier B. Mars,Rogier B. Mars +6 more
TL;DR: The results suggest that the connectivity patterns for the nucleus accumbens and cortico-striatal motor circuits (posterior/lateral putamen) were conserved across species, making them reliable targets for cross-species comparisons.
Journal ArticleDOI
Resting-State Functional Connectivity in Individuals with Down Syndrome and Williams Syndrome Compared with Typically Developing Controls
Jennifer N. Vega,Timothy J. Hohman,Jennifer R. Pryweller,Elisabeth M. Dykens,Tricia A. Thornton-Wells +4 more
TL;DR: A global difference in between-network connectivity in individuals with neurodevelopmental disorders compared with controls is suggested and that such a difference is exacerbated across many brain regions in DS.
Journal ArticleDOI
Cannabis analgesia in chronic neuropathic pain is associated with altered brain connectivity
Libat Weizman,Lior Dayan,Silviu Brill,Hadas Nahman-Averbuch,Talma Hendler,Giris Jacob,Haggai Sharon +6 more
TL;DR: The results suggest that the ACC and DLPFC, 2 major cognitive-emotional modulation areas, and their connections to somatosensory areas, are functionally involved in the analgesic effect of THC in chronic pain.

Resting state connectivity immediately following learning correlates with subsequent sleep-dependent enhancement of motor task performance
Michael D. Gregory,Michael D. Gregory,Yigal Agam,Chindhuri Selvadurai,Amanda Nagy,Mark Vangel,Matthew A. Tucker,Matthew A. Tucker,Edwin M. Robertson,Edwin M. Robertson,Robert Stickgold,Robert Stickgold,Dara S. Manoach +12 more
TL;DR: The findings demonstrate that physiological processes immediately after learning correlate with sleep-dependent performance improvement and suggest that the wakeful resting brain prepares memories of recent experiences for later consolidation during sleep.

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.
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.
