Unravelling the Intrinsic Functional Organization of the Human Striatum: A Parcellation and Connectivity Study Based on Resting-State fMRI
TL;DR: This study applies unsupervised clustering algorithms to parcellate the human striatum based on its functional connectivity patterns to other brain regions without any anatomically or functionally defined cortical targets, showing similar striatal parcellation patterns between the present and prior studies.
Journal ArticleDOI
Towards precise brain stimulation: Is electric field simulation related to neuromodulation?
Daria Antonenko,Axel Thielscher,Guilherme B. Saturnino,Semiha Aydin,Bernd Ittermann,Ulrike Grittner,Agnes Flöel +6 more
TL;DR: The findings corroborate previous reports on tDCS-induced neurophysiological modulations and further advance the understanding of underlying mechanisms by providing first empirical evidence for the association of the injected electric field and neuromodulatory effects.
Journal ArticleDOI
Neural Processes in the Human Temporoparietal Cortex Separated by Localized Independent Component Analysis
TL;DR: The results show that the TPJ in both hemispheres hosts multiple neural processes with connectivity patterns consistent with well developed specialization and lateralization.

Abnormal reward circuitry in anorexia nervosa: A longitudinal, multimodal MRI study
Jiook Cha,Jaime S. Ide,F. DuBois Bowman,Helen Blair Simpson,Jonathan Posner,Joanna E. Steinglass +5 more
TL;DR: The findings from this longitudinal, multimodal neuroimaging study offer converging evidence of atypical fronto‐accumbal circuitry in AN.

Brain differences between persistent and remitted attention deficit hyperactivity disorder
Aaron T. Mattfeld,Aaron T. Mattfeld,John D. E. Gabrieli,Joseph Biederman,Thomas J. Spencer,Ariel Brown,Amelia Kotte,Elana Kagan,Susan Whitfield-Gabrieli,Susan Whitfield-Gabrieli +9 more
TL;DR: The neurobiological dissociation between the persistence and remittance of attention deficit hyperactivity disorder may provide a framework for the relation between the clinical diagnosis, which indicates the need for treatment, and additional deficits that are common, such as executive dysfunctions.

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.
