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

From State-to-Trait Meditation: Reconfiguration of Central Executive and Default Mode Networks.
Clemens C. C. Bauer,Susan Whitfield-Gabrieli,Susan Whitfield-Gabrieli,José Luis Díaz,Erick H. Pasaye,Fernando A. Barrios,Fernando A. Barrios +6 more
TL;DR: The gradual reconfiguration in DMN and CEN suggest a neural mechanism by which the CEN negatively regulates theDMN and is probably responsible for the long-term trait changes seen in meditators and reported psychological well-being.

Serotonergic Psychedelics LSD & Psilocybin Increase the Fractal Dimension of Cortical Brain Activity in Spatial and Temporal Domains
Thomas F. Varley,Thomas F. Varley,Robin L. Carhart-Harris,Leor Roseman,David K. Menon,Emmanuel Stamatakis +5 more
TL;DR: Evidence is found that the activity of the brain on psychedelics is more fractal than normal, and this is interpreted as supporting the theory that, psychedelic drugs are move the brain towards a more critical state.

Brain Functional Magnetic Resonance Imaging Highlights Altered Connections and Functional Networks in Patients With Hypertension.
Lorenzo Carnevale,Angelo Maffei,Alessandro Landolfi,Giovanni Grillea,Daniela Carnevale,Giuseppe Lembo +5 more
TL;DR: Resting-state functional magnetic resonance imaging is used to explore brain functional-hemodynamic coupling across different regions and their connectivity in patients with hypertension, as compared to subjects with normotension, and shows that hypertensive brains present a network of functional connectivity alterations that correlate with cognitive dysfunction and microstructural integrity.

Does brain functional connectivity contribute to musculoskeletal injury? A preliminary prospective analysis of a neural biomarker of ACL injury risk.
Jed A. Diekfuss,Dustin R. Grooms,Weihong Yuan,Jonathan Dudley,Kim D. Barber Foss,Staci Thomas,Jonathan D. Ellis,Daniel K. Schneider,James L. Leach,Scott Bonnette,Gregory D. Myer +10 more
TL;DR: Preliminary data indicate that those who do not later sustain an ACL injury exhibit a stronger functional connection between a cortical sensory-motor region and a cerebellar region responsible for balance and coordination.

Subcortical Glutamate Mediates the Reduction of Short-Range Functional Connectivity with Age in a Developmental Cohort
Carmen Ghisleni,Steffen Bollmann,Simon-Shlomo Poil,Daniel Brandeis,Ernst Martin,Lars Michels,Ruth L. O'Gorman,Peter Klaver +7 more
TL;DR: It is suggested that lower Glu mediates a reduction of local connectivity during human development as well as the potential role of Glu in synaptic pruning.

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.
