The white matter is white because of the fatty substance (myelin) that surrounds the nerve fibers (axons). This myelin is found in almost all

Cerebral white matter lesions (WMLs) have been associated with cognitive dysfunction. Whether periventricular or subcortical WMLs relate differently to cognitive function is still uncertain. In addition, it is unclear whether WMLs are related to specific cognitive domains such as memory or psychomot … White matter constitutes nearly half of brain volume.1,2 Consisting of billions of myelinated axons that travel within and between the hemispheres to connect gray matter regions with each other, white matter occupies a central position that is important in both brain structure and function (Figure 1).

Changes in white matter as determinant of global functional decline in older independent outpatients: three year follow-up of LADIS 5 Apr 2021 The geodesic ray-tracing method has shown its effectiveness for the reconstruction of fibers in white matter structure.

The main function of white matter in the brain is to regulate the electrical signals in axons. 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. 2021-04-02 · Myelin gives the white matter its color. It also protects the nerve fibers from injury.

2020-06-07 · White matter's job is to conduct, process, and send nerve signals up and down the spinal cord. Damage to the white matter of your brain or spinal cord can affect your ability to move, use your sensory faculties, or react appropriately to external stimuli. Some people with damaged white matter suffer deficits in reflexive reactions.
