Fehérállományi

Fehérállományi is a Hungarian term that translates to "white matter" in English. In neuroanatomy, white matter refers to the areas of the central nervous system (CNS) that are primarily composed of myelinated nerve fibers. Myelin is a fatty substance that insulates the axons of neurons, allowing for faster and more efficient transmission of nerve impulses. These myelinated axons are bundled together to form tracts, which connect different regions of the CNS. The white appearance of these areas is due to the high lipid content of myelin.

White matter plays a crucial role in communication within the brain and spinal cord. It acts as a highway system, transmitting signals between gray matter regions (which contain neuronal cell bodies) and between different parts of the brain. Diseases or injuries affecting white matter, such as multiple sclerosis or traumatic brain injury, can disrupt these communication pathways, leading to a variety of neurological symptoms. The study of white matter and its pathways, often through techniques like diffusion tensor imaging (DTI), is essential for understanding brain function and diagnosing neurological disorders.
