White matter is a type of tissue found in the brain and spinal cord, primarily composed of myelinated axons. These axons are long projections of nerve cells that transmit signals between different parts of the nervous system. The myelin sheath, which surrounds these axons, gives white matter its characteristic color and helps speed up the transmission of electrical signals. White matter plays a crucial role in communication within the brain, connecting various regions and facilitating coordination of functions. It is essential for processes such as learning, memory, and motor control. Damage to white matter can lead to neurological disorders and impairments in cognitive and physical abilities.
