The White Matter Query Language: A Novel Approach for Describing Human White Matter Anatomy [PDF]
, 2015 We have developed a novel method to describe human white matter anatomy using an approach that is both intuitive and simple to use, and which automatically extracts white matter tracts from diffusion MRI volumes. Further, our method simplifies the quantification and statistical analysis of white matter tracts on large diffusion MRI databases. This work

BundleSeg: A versatile, reliable and reproducible approach to white matter bundle segmentation [PDF]
arXiv, 2023 This work presents BundleSeg, a reliable, reproducible, and fast method for extracting white matter pathways. The proposed method combines an iterative registration procedure with a recently developed precise streamline search algorithm that enables efficient segmentation of streamlines without the need for tractogram clustering or simplifying ...

Dark Matter-admixed Rotating White Dwarfs as Peculiar Compact Objects [PDF]
, 2021 The discoveries of anomalous compact objects challenge our understanding of the standard theory of stellar structures and evolution. They serve as an excellent laboratory to search for new physics. Earlier studies on spherically symmetric dark matter-admixed compact stars could explain a handful of anomalies.

Brain White Matter: A Substrate for Resilience and a Substance for Subcortical Small Vessel Disease
Brain Sciences, 2019 Age-related brain white matter disease is a form of small vessel disease (SVD) that may be associated with lacunar and other small subcortical infarcts, cerebral microbleeds, and perivascular spaces.

Functional connectivity of white matter as a biomarker of cognitive decline in Alzheimer's disease.
PLoS ONE, 2020 ObjectiveIn vivo functional changes in white matter during the progression of Alzheimer's disease (AD) have not been previously reported. Our objectives are to measure changes in white matter functional connectivity (FC) in an elderly population ...

Characterization of White Matter Hyperintensities in Large-Scale MRI-Studies
Frontiers in Neurology, 2019 Background: White matter hyperintensities of presumed vascular origin (WMH) are a common finding in elderly people and a growing social malady in the aging western societies. As a manifestation of cerebral small vessel disease, WMH are considered to be a

Compression analysis of the gray and white matter of the spinal cord
Neural Regeneration Research, 2020 The spinal cord is composed of gray matter and white matter. It is well known that the properties of these two tissues differ considerably. Spinal diseases often present with symptoms that are caused by spinal cord compression.
