Construction and validation of a cerebral white matter hyperintensity probability map of older Koreans

open access: yesNeuroImage: Clinical, 2021
Background and purpose: Although two white matter hyperintensity (WMH) probability maps of healthy older adults already exist, they have several limitations in representing the distribution of WMH in healthy older adults, especially Asian older adults ...

White matter development in early puberty: a longitudinal volumetric and diffusion tensor imaging twin study.

open access: yesPLoS ONE, 2012
White matter microstructure and volume show synchronous developmental patterns in children. White matter volume increases considerably during development.

Vanishing white matter disease

open access: yesPaediatria Croatica, 2009
Vanishing White Matter Disease (VWMD) is one of the most prevalent inherited white matter disorders in childhood, with a large variety in the age of onset and rate of progression. The classical and most common type shows its onset between the ages of 2 and 6 years in children with initially normal motor and mental development.

White matter changes and confrontation naming in retired aging national football league athletes [PDF]

open access: yes, 2017
Using diffusion tensor imaging (DTI), we assessed the relationship of white matter integrity and performance on the Boston Naming Test (BNT) in a group of retired professional football players and a control group.

White Matter Regions With Low Microstructure in Young Adults Spatially Coincide With White Matter Hyperintensities in Older Adults

open access: yesFrontiers in Aging Neuroscience, 2019
Microstructural and macrostructural white matter damage occurs frequently with aging, is associated with negative health outcomes, and can be imaged non-invasively as fractional anisotropy (FA) and white matter hyperintensities (WMH), respectively.

Nuclear Mixing Meters for Classical Novae [PDF]

open access: yes, 2013
Classical novae are caused by mass transfer episodes from a main sequence star onto a white dwarf via Roche lobe overflow. This material forms an accretion disk around the white dwarf.

APPLICATION OF STEREOLOGICAL METHODS TO STUDY THE WHITE MATTER AND MYELINATED FIBERS THEREIN OF RAT BRAIN

open access: yesImage Analysis and Stereology, 2011
An efficient and unbiased stereological method was applied to estimate the white matter volume, the total volume, total length and mean diameter of the myelinated fibers in the white matter and the total volume of the myelin sheaths in the white matter ...

Association between gray/white matter contrast and white matter microstructural alterations in medication-naïve obsessive–compulsive disorder

open access: yesNeuroImage: Clinical, 2022
Intracortical myelin is involved in speeding and synchronizing neural activity of the cerebral cortex and has been found to be disrupted in various psychiatric disorders. However, its role in obsessive–compulsive disorder (OCD) has remained unknown.

Damage to Association Fiber Tracts Impairs Recognition of the Facial Expression of Emotion [PDF]

open access: yes, 2009
An array of cortical and subcortical structures have been implicated in the recognition of emotion from facial expressions. It remains unknown how these regions communicate as parts of a system to achieve recognition, but white matter tracts are likely ...
