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

Spectral Diversity in Default Mode Network Connectivity Reflects Behavioral State.
TL;DR: Results show that DMN does not simply deactivate during task execution and suggest active recruitment while performing cognitively demanding paradigms, suggesting an important role for high-frequency fluctuations in functional integration.

The Endogenous Analgesia Signature in the Resting Brain of Healthy Adults and Migraineurs.
Yuval Argaman,Lee B Kisler,Yelena Granovsky,Yelena Granovsky,Robert C. Coghill,Elliot Sprecher,David Manor,David Manor,Irit Weissman-Fogel +8 more
TL;DR: Evidence is established for the relationship between the resting-state brain and individual responses in psychophysical pain modulation tests, in both migraine and healthy individuals, and the significant role of the default mode network in maintaining pain inhibition efficiency in heath and in the presence of chronic pain is emphasized.

Associative reinstatement memory measures hippocampal function in Parkinson's Disease
Melanie Cohn,Melanie Cohn,Irene Giannoylis,Maya De Belder,Jean A. Saint-Cyr,Mary Pat McAndrews,Mary Pat McAndrews +6 more
TL;DR: ARM is a sensitive measure of hippocampal memory function that is unaffected by attention or executive dysfunction in PD, and highlights the benefit of integrating cognitive neuroscience frameworks and novel experimental tasks to improve the practice of clinical neuropsychology in PD.

Spin-Echo Resting-State Functional Connectivity in High-Susceptibility Regions: Accuracy, Reliability, and the Impact of Physiological Noise
TL;DR: This work quantifies the sensitivity and specificity of SE and GE EPI for resting-state fMRI functional connectivity (fcMRI) mapping, using the 1000-brain fcMRI atlas as the pseudoground truth and suggests that SE-EPI should be increasingly adopted in the study of networks spanning susceptibility-affected brain regions, including those that are important to memory, language, and emotion.

TL;DR: In this paper, structural and functional alterations of the reward system and the neurobiology of craving in alcohol use disorder (AUD) were investigated, and it was found that increased OFC-NAcc functional connectivity was associated with increased craving.

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.
