The Robustness of White Matter Brain Networks Decreases with Aging
Journal of Integrative NeuroscienceBackground: White matter (WM) is a principal component of the human brain, forming the structural basis for neural transmission between cortico-cortical and subcortical structures.

Alzheimer’s Research & TherapyBackground White matter hyperintensities (WMH) are considered hallmark features of cerebral small vessel disease and have recently been linked to Alzheimer’s disease (AD) pathology. Their distinct spatial distributions, namely periventricular versus deep

Improved functional MRI activation mapping in white matter through diffusion-adapted spatial filtering [PDF]
arXiv, 2019 Brain activation mapping using functional MRI (fMRI) based on blood oxygenation level-dependent (BOLD) contrast has been conventionally focused on probing gray matter, the BOLD contrast in white matter having been generally disregarded. Recent results have provided evidence of the functional significance of the white matter BOLD signal, showing at the ...

Crystallinity characterization of white matter in the human brain [PDF]
arXiv, 2020 White matter microstructure underpins cognition and function in the human brain through the facilitation of neuronal communication, and the non-invasive characterization of this structure remains a research frontier in the neuroscience community. Efforts to assess white matter microstructure, however, are hampered by the sheer amount of information ...

Considerations for the optimization of induced white matter injury preclinical models
Frontiers in Neurology, 2015 The white matter injury in relation to acute neurologic conditions, especially stroke, has remained obscure until recently. Current advances in the imaging technologies in the field of stroke have confirmed that white matter injury plays an important ...

A Unique Analytical Solution of the White Matter Standard Model using Linear and Planar Encodings [PDF]
arXiv, 2018 Diffusion-weighted magnetic resonance imaging in brain white matter probes tissue microstructure and allows for the estimation of compartmental diffusion parameters. Recently, it became apparent that traditional single-direction diffusion encodings are not fully sufficient to resolve the white matter compartmental diffusivities.

Neurobiology of Sleep and Circadian Rhythms, 2016 Sleep apnea has been related to brain changes such as atrophy. However, which component of sleep apnea, the apnea-hypopnea index (AHI), nocturnal oxygen desaturation or arousals, can explain this association is unclear.

The white dwarf luminosity function [PDF]
, 2016 White dwarfs are the final remnants of low- and intermediate-mass stars. Their evolution is essentially a cooling process that lasts for $\sim 10$ Gyr. Their observed properties provide information about the history of the Galaxy, its dark matter content and a host of other interesting astrophysical problems.
