White matter fiber tracking directed by interpolating splines and a methodological framework for evaluation

Frontiers in Neuroinformatics, 2013
Image-based tractography of white matter (WM) fiber bundles in the brain using diffusion weighted MRI (DW-MRI) has become a useful tool in basic and clinical neuroscience.

DTI‐ALPS Primarily Reflects White Matter Diffusion Dispersion and Microstructural Heterogeneity in Neurodegeneration: Insights From Multi‐Modal MRI

Human Brain Mapping, Volume 47, Issue 14, October 1, 2026.
In a 100‐patient memory‐clinic cohort, DTI‐ALPS was evaluated along with diffusion and microstructural metrics. DTI‐ALPS correlated strongly with mode of anisotropy and orientation dispersion index, and moderately with T1/FLAIR ratio and diamagnetic susceptibility, indicating that DTI‐ALPS mainly reflects white‐matter diffusion complexity rather than ...

Charting the Normal Development of Structural Brain Connectivity in Utero Using Diffusion MRI

Human Brain Mapping, Volume 47, Issue 14, October 1, 2026.
This study proposes new methods to study the development of the structural connectivity in utero using diffusion‐weighted MRI. The methods are applied on data from around 200 fetal brains to chart how the structural connectome develops between 22 and 37 gestational weeks.

Adjugate diffusion tensors for geodesic tractography in white matter [PDF]

, 2015
One of the approaches in diffusion tensor imaging is to consider a Riemannian metric given by the inverse diffusion tensor. Such a metric is used for geodesic tractography and connectivity analysis in white matter. We propose a metric tensor given by the

Spherical-deconvolution informed filtering of tractograms changes laterality of structural connectome

NeuroImage
Diffusion MRI-driven tractography, a non-invasive technique that reveals how the brain is connected, is widely used in brain lateralization studies.

Investigating the Neural Bases of Egocentric Spatial Reference Frame After Right‐Hemisphere Stroke: Brain Lesions and Disconnectome Analyses of Subjective Straight Ahead and Longitudinal Body Axis Misperception

Human Brain Mapping, Volume 47, Issue 14, October 1, 2026.
The figure illustrates distinct neural substrates for egocentric body reference after right‐hemisphere stroke. SSA distortions are linked to right fronto‐parietal lesions and posterior corpus callosum disconnections, whereas LBA distortions involve temporo‐occipital damage and inferior longitudinal fasciculus disconnections, emphasising a functional ...

Individualised Structural and Functional Frontostriatal Connectivity Mapping in Adult ADHD

Human Brain Mapping, Volume 47, Issue 14, October 1, 2026.
We identified compromised structural and functional frontostriatal connectivity in adults with attention deficit hyperactivity disorder via individualised connectivity mapping. ABSTRACT Abundant research from early neurocognitive models to recent mega‐analyses has highlighted the central role of frontostriatal circuits in attention deficit ...

Intramuscular Fat as a Biomarker of Muscle Health: Strengths, Limitations and Open Challenges

Journal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 5, October 2026.
ABSTRACT Intramuscular fat (IMF), also known as myosteatosis, refers to the accumulation of lipids within and around skeletal muscle fibres. Excess IMF is increasingly recognised as a sign of poor muscle quality, linked to reductions in strength, power and mobility, and associated with adverse outcomes in metabolic disease, osteoarthritis ...

Delivery and Attitude Modulate Shared Neural Processing of Speech Through Distinct Frequency Channels

Psychophysiology, Volume 63, Issue 10, October 2026.
ABSTRACT Listeners' brains align when they attend to the same speech, but what determines how strongly they align is not well understood. We asked whether that alignment tracks the communicative relation between a listener and a message, manipulating it from the speaker's side and from the listener's, and bounding the account with a manipulation that ...

Individual differences in white matter microstructure reflect variation in functional connectivity during action choice. [PDF]

, 2007
The relation between brain structure and function is of fundamental importance in neuroscience. Comparisons between behavioral and brain imaging measures suggest that variation in brain structure correlates with the presence of specific skills[1-3 ...
