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

TL;DR: Comparisons of brain activity measured by functional magnetic resonance imaging and behavioral parameters associated with movement, motivation, and cognitive control between 18 stable SCZ patients and 17 healthy control participants during a task that elicits intrinsic motivation suggest that, unlike HC, the neural activity in the LPFC fails to mediate between prediction of hedonic events and Cognitive control of action plans in SCZ, whereas the hedonics response is retained.

Cortical reorganisation of cerebral networks after childhood stroke: impact on outcome
Salome Kornfeld,Juan Antonio Delgado Rodríguez,Regula Everts,Alain Kaelin-Lang,Roland Wiest,Christian Weisstanner,Pasquale Mordasini,Maja Steinlin,Sebastian Grunt +8 more
TL;DR: This study is the first to combine resting state functional magnetic resonance imaging and transcranial magnetic stimulation in a paediatric population diagnosed with arterial ischaemic stroke and has the potential to uniquely contribute to the understanding of neuronal plasticity in the brains of healthy children and those with acute or chronic brain injury.

Alcohol Effects on Globus Pallidus Connectivity: Role of Impulsivity and Binge Drinking
Samantha J. Fede,Karina Possa Abrahao,Carlos R. Cortes,Erica N. Grodin,Melanie L. Schwandt,David T. George,Nancy Diazgranados,Vijay A. Ramchandani,David M. Lovinger,Reza Momenan +9 more
TL;DR: It is suggested that alcohol may interact with impulsive personality traits and drinking patterns to drive alterations in GPe circuitry associated with behavioral inhibition, possibly indicating a neural mechanism by which binge drinking could lead to impulsive behaviors.

Somatosensory network functional connectivity differentiates clinical pain phenotypes in diabetic neuropathy.
Kevin Teh,Iain D. Wilkinson,Francesca Heiberg-Gibbons,Mohammed Awadh,Alan Kelsall,Shillo Pallai,Gordon Sloan,Solomon Tesfaye,Dinesh Selvarajah +8 more
TL;DR: In this paper, the authors investigated whether different clinical pain phenotypes of diabetic polyneuropathy (DPN) are distinguished by functional connectivity at rest and found that individuals with the IR nociceptor phenotype had significantly greater thalamic-insular cortex (p false discovery rate [FDR] = 0.03) and reduced thalamus-somatosensory cortex functional connectivity.

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.

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.
