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

Changes in Brain Function and Structure After Self-Administered Home Photobiomodulation Treatment in a Concussion Case.
TL;DR: After 8 weeks of PBM treatments, increased brain volumes, improved functional connectivity, and increased cerebral perfusion and improvements on neuropsychological test scores were observed, encouraging replication studies that could provide further validation for this non-invasive, non-pharmacological modality as a viable treatment option for TBI.

Karam,Marcelo M. Victor,Vitor Breda,Katiane L. Silva,Neivo da Silva,Claiton H.D. Bau,Eugenio H. Grevet,Luis Augusto Rohde,Luis Augusto Rohde +17 more
TL;DR: The results contribute to the further understanding on how MPH affects functional connectivity within DMN of male adults with ADHD and corroborate the hypothesis of ADHD being a delayed neurodevelopmental disorder.

TL;DR: Findings suggest that abnormalities in functional communication in a network encompassing right STG and associated brain regions are present before adolescence in at-risk children and may be a risk marker for psychosis.

Resting-state functional brain networks in adults with a new diagnosis of focal epilepsy
Batil Alonazi,Batil Alonazi,Simon Keller Keller,Simon Keller Keller,Nicholas Fallon,V.L. Adams,Kumar Das,Anthony G Marson,Vanessa Sluming +8 more
TL;DR: This study investigated whether patients with NDfE had altered connectivity in large‐scale functional networks using resting‐state functional MRI, and found that they did.
Journal ArticleDOI
Task-linked diurnal brain network reorganization in older adults: A graph theoretical approach
John A. E. Anderson,Saman Sarraf,Tarek Amer,Buddhika Bellana,Vincent Man,Karen L. Campbell,Lynn Hasher,Cheryl L. Grady +7 more
TL;DR: This study used graph theory to explore how time of day (TOD) affects the organization of brain networks in older adults across rest and task states and found that older adults tested in the morning and young adults did not differ on any graph metric.

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.
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.
