TLDR
A recent study shows that the fronto-parietal network, and subregions therein, alters its functional connectivity with nodes of other networks based on task goals, and serves as a code that can be transferred to facilitate learning novel tasks.About:

Applications of transcranial direct current stimulation for understanding brain function
TL;DR: It is explained how oscillatory tDCS can elucidate the role of fluctuations in neural activity, in both frequency and phase, in perception, learning, and memory.

TL;DR: Findings provide initial evidence that depression, and ruminative thinking in depression, are related to abnormal patterns of fluctuating communication among brain systems involved in regulating attention and self-referential thinking.

A Connectome Wide Functional Signature of Transdiagnostic Risk for Mental Illness
TL;DR: Initial evidence is provided that the transdiagnostic risk for common forms of mental illness is associated with patterns of inefficient connectome-wide intrinsic connectivity between visual association cortex and networks supporting executive control and self-referential processes, networks that are often impaired across categorical disorders.

TL;DR: Structural and resting-state functional magnetic resonance imaging scans from 482 healthy subjects are employed and the vertex-wise regional homogeneity of low-frequency fluctuations (2dReHo) and five measures of cortical morphology are computed to suggest that local functional homogeneity has neurobiological relevance that is likely determined by anatomical, developmental and neurocognitive factors.

TL;DR: A winner-take-all partitioning method is applied to resting-state fMRI data to generate novel functionally-constrained ROIs in the thalamus, basal ganglia, amygdala, hippocampus, and cerebellum, and it is demonstrated that combining these ROIs with established cortical ROIs recapitulates and extends previously described functional network organization.

TL;DR: In this article, the authors studied functional brain organization in healthy adults using resting state functional connectivity MRI and proposed two novel brain wide graphs, one of 264 putative functional areas, the other a modification of voxelwise networks that eliminates potentially artificial short-distance relationships.

TL;DR: It was found that the FPN's brain-wide functional connectivity pattern shifted more than those of other networks across a variety of task states and that these connectivity patterns could be used to identify the current task.

TL;DR: It is shown that multitasking performance, as assessed with a custom-designed three-dimensional video game (NeuroRacer), exhibits a linear age-related decline from 20 to 79 years of age, and is the first evidence, to the authors' knowledge, of how a CustomRacer can be used to assess cognitive abilities across the lifespan, evaluate underlying neural mechanisms, and serve as a powerful tool for cognitive enhancement.

Network attributes for segregation and integration in the human brain.
TL;DR: This review surveys a number of recent reports on network communities and hubs, and their role in integrative processes, which manifest in continuously changing patterns of functional interactions between regions, circuits and systems.
