White Matter-Gray Matter Correlation Analysis Based on White Matter Functional Gradient [PDF]

Brain Sciences
Background: The spontaneous fluctuations in functional magnetic resonance imaging (fMRI) signals of the brain’s gray matter (GM) have been interpreted as representations of neural activity variations.

Regional vulnerability of brain white matter in vanishing white matter

Acta Neuropathologica Communications, 2023
Vanishing white matter (VWM) is a leukodystrophy that primarily manifests in young children. In this disease, the brain white matter is differentially affected in a predictable pattern with telencephalic brain areas being most severely affected, while ...

White dwarfs and Galactic dark matter [PDF]

Mon.Not.Roy.Astron.Soc. 339 (2003) 817, 2002
We discuss the recent discovery by Oppenheimer et al (2001) of old, cool white dwarf stars, which may be the first direct detection of Galactic halo dark matter. We argue here that the contribution of more mundane white dwarfs of the stellar halo and thick disk would contribute sufficiently to explain the new high velocity white dwarfs without invoking

Section on Prospects for Dark Matter Detection of the White Paper on the Status and Future of Ground-Based TeV Gamma-Ray Astronomy [PDF]

arXiv, 2008
This is a report on the findings of the dark matter science working group for the white paper on the status and future of TeV gamma-ray astronomy. The white paper was commissioned by the American Physical Society, and the full white paper can be found on astro-ph (arXiv:0810.0444). This detailed section discusses the prospects for dark matter detection

White‐Matter Structural Connectivity and Alzheimer's Disease: A Mendelian Randomization Study [PDF]

Brain and Behavior
Background Alzheimer's disease (AD) and white‐matter structural connectivity have been linked in some observational studies, although it is unknown if this is a causal relationship.

Metachromatic leukodystrophy and transplantation: remyelination, no cross‐correction

Annals of Clinical and Translational Neurology, 2020
Objective In metachromatic leukodystrophy, a lysosomal storage disorder due to decreased arylsulfatase A activity, hematopoietic stem cell transplantation may stop brain demyelination and allow remyelination, thereby halting white matter degeneration ...

Ultra low-mass and small-radius white dwarfs made of heavy elements [PDF]

Front. Astron. Space Sci. 10 (2023) 1334642, 2023
Seven ultra low-mass and small-radius white dwarfs (LSPM J0815+1633, LP 240-30, BD+20 5125B, LP 462-12, WD J1257+5428, 2MASS J13453297+4200437, and SDSS J085557.46+053524.5) have been recently identified with masses ranging from $\sim$0.02 $M_\odot$ to $\sim$0.08 $M_\odot$ and radii from $\sim$ 4270 km to 10670 km. The mass-radius measurements of these

Association between Perivascular Spaces and Progression of White Matter Hyperintensities in Lacunar Stroke Patients. [PDF]

PLoS ONE, 2015
Perivascular spaces are associated with MRI markers of cerebral small vessel disease, including white matter hyperintensities. Although perivascular spaces are considered to be an early MRI marker of cerebral small vessel disease, it is unknown whether ...

Constraining dark matter interactions mediated by a light scalar with white dwarfs [PDF]

, 2022
Observations of white dwarfs in dark matter-rich environments can provide strong limits on the strength of dark matter interactions. Here we apply the recently improved formalism of the dark matter capture rate in white dwarfs to a general model in which dark matter interacts with the white dwarf ion components via a light scalar mediator.
