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

Functional neuroanatomical evidence for the double-deficit hypothesis of developmental dyslexia
Elizabeth S. Norton,Jessica M. Black,Leanne M. Stanley,Hiroko Tanaka,John D. E. Gabrieli,Carolyn Sawyer,Fumiko Hoeft,Fumiko Hoeft,Fumiko Hoeft +8 more
TL;DR: The double-deficit hypothesis of dyslexia as discussed by the authors posits that both rapid naming and phonological impairments can cause reading difficulties, and that individuals who have both of these deficits show greater reading impairments compared to those with a single deficit.

Effect of Intrinsic Patterns of Functional Brain Connectivity in Moderating Antidepressant Treatment Response in Major Depression
Cherise Chin Fatt,Manish K. Jha,Manish K. Jha,Crystal Cooper,Gregory A. Fonzo,Gregory A. Fonzo,Charles South,Bruce D. Grannemann,Thomas J. Carmody,Tracy L. Greer,Benji T. Kurian,Maurizio Fava,Patrick J. McGrath,Phillip Adams,Melvin G. McInnis,Ramin V. Parsey,Myrna M. Weissman,Mary L. Phillips,Amit Etkin,Amit Etkin,Madhukar H. Trivedi +20 more
TL;DR: Functional connectivity patterns of brain regions between and within networks appear to play an important role in identifying a favorable response for a drug treatment for major depressive disorder.

Resting-state thalamic dysconnectivity in schizophrenia and relationships with symptoms.
Jamie Ferri,James M. Ford,Brian J. Roach,Jessica A. Turner,T.G.M. van Erp,James T. Voyvodic,Adrian Preda,Aysenil Belger,Juan R. Bustillo,Daniel S. O'Leary,Bryon A. Mueller,Kelvin O. Lim,Sarah McEwen,Vince D. Calhoun,Michele T. Diaz,Gary H. Glover,Douglas N. Greve,Cynthia G. Wible,Jatin G. Vaidya,Steven G. Potkin,Daniel H. Mathalon +20 more
TL;DR: Thalamic hyperconnectivity with sensory regions and hypoconnectivity with cerebellar regions in combination with their relationship to clinical features of SZ suggest that thalamic dysconnectivity may be a core neurobiological feature of Sz that underpins positive symptoms.
Journal ArticleDOI
LSD alters dynamic integration and segregation in the human brain.
Andrea I. Luppi,Robin L. Carhart-Harris,Leor Roseman,Ioannis Pappas,David K. Menon,Emmanuel Stamatakis +5 more
TL;DR: Increased small-worldness of brain networks predicts LSD-induced ego-dissolution and untethers functional connectivity from the constraint of structural connectivity, which bridge pharmacodynamics, subjective experience and brain dynamics.
Journal ArticleDOI
Effects of rTMS of Pre-Supplementary Motor Area on Fronto Basal Ganglia Network Activity during Stop-Signal Task
Takamitsu Watanabe,Ritsuko Hanajima,Yuichiro Shirota,Ryosuke Tsutsumi,Takahiro Shimizu,Toshihiro Hayashi,Yasuo Terao,Yoshikazu Ugawa,Masaki Katsura,Akira Kunimatsu,Kuni Ohtomo,Satoshi Hirose,Yasushi Miyashita,Seiki Konishi +13 more
TL;DR: A causal relationship between pre-SMA and GPi via STR during response inhibition is suggested, and direct evidence that the fronto basal ganglia network for response inhibition consists of multiple top-down regulation pathways in humans is added.

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.
