The key feature is the myelin coating. Myelin is a structure built from a mixture of lipids and proteins. It is responsible for axon protection and conducting nerve signals to the spinal cord. If the white matter is damaged, this can affect sensory functions, moving, and White matter tracts mediate the essential connectivity by which human behavior is organized, working in concert with gray matter to enable the extraordinary repertoire of human cognitive capacities. 2021-01-19 · The function of the white matter in the spinal cord is to convey information from the nervous systems to the brain, or from the brain to the systems. The spinal cord is made up of grey matter and white matter. A fatty material called myelin protects the fibers and gives white matter its color.

MS is predominantly a disease of the white matter in the CNS. About 95% of all lesions associated with MS occur in the white matter. White matter refers to areas of the central nervous system (CNS) that are mainly made up of myelinated axons, also called tracts. Long thought to be passive tissue, white matter affects learning and brain functions, modulating the distribution of action potentials, acting as a relay and coordinating By using two different cognitive functions we had the possibility to demonstrate some specificity of maturation (e.g., that maturation of a white matter region is more associated with development of one function and less with another). WM is most closely related to the function of the dorsolateral prefrontal cortex. The particular WM Patients with type 2 diabetes mellitus (T2DM) have a considerably high risk of developing dementia, especially for those with mild cognitive impairment (MCI). The investigation of the microstructural change of white matter (WM) between T2DM with amnesic MCI (T2DM-aMCI) and T2DM with normal cognition (T2DM-NC) and their relationships to cognitive performances can help to understand the brain 2012-10-30 · White matter lesions (WMLs) are associated with reduced cognitive function in older adults. However, whether their anatomical location moderates these associations is not well-established.

4 Oct 2019 White matter is a vital part of the human brain, but in functional magnetic resonance imaging (fMRI), it remains largely overlooked and

"White matter enables the brain to operate intact." In the normal brain, white matter appears to provide the essential connectivity, uniting different regions into networks that perform various mental operations. We know this because, when this connectivity is disrupted by disease or other damage to white matter, the result is often a dramatic disturbance of normal mental function. White matter is tissue in the brain composed of nerve fibers. The fibers (called axons) connect nerve cells and are covered by myelin (a type of fat). The myelin is what gives white matter its white color.

White matter disease targets small blood vessels deep inside white matter in the brain. In turn, these tiny arteries are then hardened, making it difficult for nutrients to access cells in the white matter.
