Sep 18, 2023 · White matter essentially acts as the brain's communication network, connecting different parts of gray matter and facilitating coordinated brain function. White matter in the brain consists of myelinated axons, which are nerve fibers covered by a fatty insulating layer called myelin.
Oct 30, 2023 · In the brain, white matter is situated beneath the gray matter of the cortex and connects various gray matter areas within the brain to each other. It contains three major groups of axons: association fibers, commissural fibers, and projection fibers.

Aug 16, 2017 · White matter is as integral to brain function as its gray neighbor; it is dynamic, involved in learning, and helps us to lay down skills and memories.
May 21, 2023 · White matter axons connect nerve cells (neurons). Myelin speeds up the signals between the cells, enabling the brain cells to quickly send and receive messages. It also provides insulation for the fibers, preventing the brain from short-circuiting.

May 4, 2022 · White matter disease is an umbrella term for damage to your brain’s white matter caused by reduced blood flow to the tissue. It can cause issues with memory, balance and mobility. People who have risk factors for cardiovascular disease also have a greater risk of developing white matter disease.
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 communication between different brain regions.
Nov 1, 2016 · Abstract. 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 recognized as equally critical for cognition.
