Dissociation of structural and functional integrities of the motor system in amyotrophic lateral sclerosis and behavioral-variant frontotemporal dementia [PDF]

open access: yes, 2016
Background and Purpose: This study investigated the structural and functional changes in the motor system in amyotrophic lateral sclerosis (ALS; n=25) and behavioral-variant fronto-temporal dementia (bvFTD; n=17) relative to healthy controls (n=37 ...

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 ...

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 ...

Characterization of White Matter Hyperintensities in Large-Scale MRI-Studies

open access: yesFrontiers 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

Functional connectivity of white matter as a biomarker of cognitive decline in Alzheimer's disease.

open access: yesPLoS 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 ...

Crystallinity characterization of white matter in the human brain

open access: yesNew Journal of Physics, 2021
Human brain tissue is a heterogeneous material, consisting of soft outer grey matter tethered internally by stiffer cords of white matter. These white matter tracts conduct electrical impulses between grey matter regions, thereby underpinning neuronal ...

Brain White Matter: A Substrate for Resilience and a Substance for Subcortical Small Vessel Disease

open access: yesBrain 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.

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.
