Diffusion tractography offers enormous potential for the study of human brain anatomy.
However, as a method to study brain connectivity, tractography suffers from limitations, as it …

Since the realization that diffusion MRI can probe the microstructural organization and
orientation of biological tissue in vivo and non‐invasively, a multitude of diffusion imaging …

Modern neuroimaging techniques provide us with unique views on brain structure and
function; ie, how the brain is wired, and where and when activity takes place. Data acquired …

Diffusion-weighted magnetic resonance (MR) signals reflect information about underlying
tissue microstructure and cytoarchitecture. We propose a quantitative, efficient, and robust …

Multiple sclerosis is characterized by inflammatory demyelination and irreversible axonal
injury leading to permanent neurological disabilities. Diffusion tensor imaging demonstrates …

To meet ongoing cognitive demands, the human brain must seamlessly transition from one
brain state to another, in the process drawing on different cognitive systems. How does the …

Brain areas' functional repertoires are shaped by their incoming and outgoing structural
connections. In empirically measured networks, most connections are short, reflecting …

Here we introduce the concept of the local connectome: the degree of connectivity between
adjacent voxels within a white matter fascicle defined by the density of the diffusing spins …

Cognitive flexibility describes the human ability to switch between modes of mental function
to achieve goals. Mental switching is accompanied by transient changes in brain activity …

How does the organization of neural information processing enable humans' sophisticated
cognition? Here we decompose functional interactions between brain regions into …
