Brain Research Reviews, 1999
Brain and spinal cord white matter are vulnerable to the effects of ischaemia. Reduction of the energy supply leads to a cascade of events including depolarization, influx of Na(+) and the subsequent reverse operation of the membrane protein the Na(+)/Ca(2+) exchanger which ultimately terminates in intracellular Ca(2+) overload and irreversible axonal ...

Impact of white matter hyperintensities on surrounding white matter tracts
Neuroradiology, 2018It is unclear how white matter hyperintensities disrupt surrounding white matter tracts. The aim of this tractography study was to determine the spatial relationship between diffusion characteristics along white matter tracts and the distance from white matter hyperintensities.Diffusion tensor 3-T MRI scans were acquired in 29 participants with white ...

White matter lactate – Does it matter?
Neuroscience, 2014About half of the human brain is white matter, characterized by axons covered in myelin, which facilitates the high speed of nerve signals from one brain area to another. At the time of myelination, the oligodendrocytes that synthesize myelin require a large amount of energy for this task.

Australian Feminist Studies, 2006
The author examines the responses to her book "Talkin' up to the White Woman: Indigenous Women and Feminism." She analyzes the nine out of almost 30 reviews written about her book which talks about power relations between white feminists and indigenous women.

Science, 2003
Scientists have long known that connections somehow go awry in the brains of people with schizophrenia. Now advances in imaging and gene technology are allowing them to trace the axons that connect from neuron to neuron and make up the brain9s white matter.

White matter pathology in phenylketonuria☆
Molecular Genetics and Metabolism, 2010Early-treated phenylketonuria (PKU) is associated with a range of neuropsychological impairments. Proposed mechanisms for these impairments include dopamine depletion and white matter pathology. Neuroimaging studies demonstrate high-signal intensity in the periventricular white matter in most PKU patients, which can extend into subcortical and frontal ...

Imaging of White Matter Lesions
Cerebrovascular Diseases, 2002Magnetic resonance imaging (MRI) is very sensitive for the detection of white matter lesions (WML), which occur even in normal ageing. Intrinsic WML should be separated from physiological changes in the ageing brain, such as periventricular caps and bands, and from dilated Virchow-Robin spaces.

"Vanishing white matter" (VWM) is a leukodystrophy caused by autosomal recessive pathogenic variants in the genes encoding the subunits of eukaryotic initiation factor 2B (eIF2B). Disease onset and disease course are extremely variable. Onset varies from the antenatal period until senescence. The age of onset is predictive of disease severity.

Learning objectives: To describe the clinical findings and MRI changes observed in patients with rapidly progressive leukodystrophy (ACER3-related), Jacobsen syndrome, X-linked adrenoleukodystrophy, metachromatic leukodystrophy, and vanishing white matter disease.
