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

Distinct hippocampal functional networks revealed by tractography-based parcellation.
Areeba Adnan,Alexander J. Barnett,Alexander J. Barnett,Massieh Moayedi,Cornelia McCormick,Cornelia McCormick,Melanie Cohn,Melanie Cohn,Mary Pat McAndrews,Mary Pat McAndrews +9 more
TL;DR: The posterior hippocampal connectivity to memory processing regions, including the dorsolateral prefrontal cortex, parahippocampal, inferior temporal and fusiform gyri and the precuneus, predicted interindividual relational memory performance and provided important support for the integration of structural and functional connectivity in understanding the brain networks underlying episodic memory.

Acupuncture treatment modulates the corticostriatal reward circuitry in major depressive disorder
Zengjian Wang,Xiaoyun Wang,Jian Liu,Jun Chen,Xian Liu,Guangning Nie,Kristen Jorgenson,Ki Cheul Sohn,Ruiwang Huang,Ming Liu,Bo Liu,Jian Kong +11 more
TL;DR: The findings suggest that acupuncture may achieve treatment effects by modulating the corticostriatal reward/motivation circuitry in MDD patients.
Journal ArticleDOI
Altered resting-state frontoparietal control network in children with attention-deficit/hyperactivity disorder.
TL;DR: An aberrant connectivity of the frontoparietal control network in ADHD was associated with symptoms of impulsivity and opposition-defiance, as well as impaired response inhibition and attentional control, and the findings support potential integration of the disconnection model and the executive dysfunction model for ADHD.
Journal ArticleDOI
Transition of the functional brain network related to increasing cognitive demands
Karolina Finc,Kamil Bonna,Monika Lewandowska,Tomasz Wolak,Jan Nikadon,Joanna Dreszer,Włodzisław Duch,Simone Kühn,Simone Kühn +8 more
TL;DR: The results show that network modularity decreased with increasing cognitive demands, and this change allowed us to predict behavioral performance, and it was found that the default mode network (DMN) increased its connectivity to other networks while decreasing connectivity between its own regions.
Journal ArticleDOI
The matter of motivation: Striatal resting-state connectivity is dissociable between grit and growth mindset
TL;DR: Grit and growth mindset were associated with functional connectivity between ventral striatal and bilateral prefrontal networks thought to be important for cognitive-behavioral control and neurocognitive models of these non-cognitive skills were constructed.

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.
