Whereas the cerebral cortex has long been regarded by neuroscientists as the major locus of cognitive function, the white matter of the brain is increasingly

2019-08-06 · The primary function of the brain's white matter is to provide a pathway for connecting the different areas of the brain. Should this brain matter become damaged, the brain can rewire itself and establish new nerve connections between gray and white matter.

(rsfMRI) study showed that higher WMH burden is associ- ated with impaired brain function [10]. 30 Aug 2017 In a prior cross-sectional study of 563 cognitively normal middle-aged relatives, we found a high prevalence of early white matter hyperintensity 30 Oct 2014 Mandell and his team hypothesized that each tiny stroke might be small enough to cause only a minor loss of brain function. Neither the patient 30 Dec 2005 We derive a simple estimate of conduction delay in global connections as a function of the number of neurons. In the third section, we consider Function. The white matter is the tissue through which messages pass between different areas of gray matter within the nervous system.

Without healthy white matter, the brain cannot function in a proper manner 2. In addition to affecting a person's ability to think clearly and make decisions, white matter disease also causes dysfunction that affects motor abilities and bodily functions 2. Whereas the cerebral cortex has long been regarded by neuroscientists as the major locus of cognitive function, the white matter of the brain is increasingly Long thought to be passive tissue, white matter actively affects how the brain learns and functions. While grey 16 Oct 2019 For example, neural diseases that result in disruption of the transit of nerve signals originate from changes in the white matter.

2017-04-01 · By delineating a network that links brain function, white-matter integrity and risk-taking behavior, these results extend the observation that FA in the pathway connecting the insula to the nucleus accumbens is associated with activation in the nucleus accumbens and with risk taking (Leong et al., 2016). More evidence has been accumulated that damage to cognitive areas is widespread from white matter disease.

White matter gets its name from the insulation covering nerve fibers. Brain Bytes showcase essential facts about neuroscience.

Although diseased white matter impairs the nervous system much like broken, frayed or poorly operating cables impair a computer network, research was mostly focused on gray matter until Charles DeCarli came along.
