Mapping the Structural Core of Human Cerebral Cortex
TLDR
The spatial and topological centrality of the core within cortex suggests an important role in functional integration and a substantial correspondence between structural connectivity and resting-state functional connectivity measured in the same participants.

Mapping complex tissue architecture with diffusion spectrum magnetic resonance imaging
TLDR
Methods are presented to map complex fiber architectures in tissues by imaging the 3D spectra of tissue water diffusion with MR, showing correspondence between the orientational maxima of the diffusion spectrum and those of the fiber orientation density at each location.

Predicting human resting-state functional connectivity from structural connectivity
TLDR
Although resting state functional connectivity is variable and is frequently present between regions without direct structural linkage, its strength, persistence, and spatial statistics are nevertheless constrained by the large-scale anatomical structure of the human cerebral cortex.

Mapping Human Whole-Brain Structural Networks with Diffusion MRI
TLDR
Based on diffusion MRI, this work proposes an efficient methodology to generate large, comprehensive and individual white matter connectional datasets of the living or dead, human or animal brain, which enables us to study the basic and potentially complex network properties of the entire brain.

White matter maturation reshapes structural connectivity in the late developing human brain
TLDR
The strengthening of the correlation between structural and functional connectivity with age suggests that white matter connectivity in combination with other factors, such as differential modulation of axonal diameter and myelin thickness, play an increasingly important role in creating brain-wide coherence and synchrony.

Understanding diffusion MR imaging techniques: from scalar diffusion-weighted imaging to diffusion tensor imaging and beyond.
TLDR
To fully understand how diffusion MR imaging works, it is helpful to be familiar with the physical principles of water diffusion in the brain and the conceptual basis of each imaging technique.

Resting-State Functional Connectivity Emerges from Structurally and Dynamically Shaped Slow Linear Fluctuations
TLDR
A dynamic mean field model is derived that consistently summarizes the realistic dynamics of a detailed spiking and conductance-based synaptic large-scale network, in which connectivity is constrained by diffusion imaging data from human subjects, and it is demonstrated that FC emerges as structured linear fluctuations around a stable low firing activity state close to destabilization.

Resting-brain functional connectivity predicted by analytic measures of network communication
TLDR
It is found that both search information and path transitivity predict the strength of functional connectivity among both connected and unconnected node pairs at levels that match or significantly exceed path length measures, Euclidean distance, as well as computational models of neural dynamics.
