  1. White matter

    White matter is one of the two components of the central nervous system and consists mostly of glial cells and myelinated axons that transmit signals from one region of the cerebrum to another and between the cerebrum and lower brain centers. White matter tissue of the freshly cut brain appears pinkish white to the naked eye because myelin is composed largely of lipid tissue veined with capillaries. Its white color is due to its usual preservation in formaldehyde. The other main component of the brain is grey matter, which is composed of neurons. A third colored component found in the brain that appears darker due to higher levels of melanin in dopaminergic neurons than its nearby areas is the substantia nigra. Note that white matter can sometimes appear darker than grey matter on a microscope slide because of the type of stain used. White matter, long thought to be passive tissue, actively affects how the brain learns and functions. Whilst grey matter is primarily associated with processing and cognition, white matter modulates the distribution of action potentials, acting as a relay and coordinating communication between different brain regions.

Examples of white matter in a Sentence

  1. Deodatta V. Shenai-Khatkhate:

    Human brain provides us an amazing example of organizational teamwork. You see, the left and right halves of human brain do function slightly differently, and yet they don't work independently or in an isolation or even in a never-ending competition as the myth goes. The two halves always work seamlessly together as a unique system; offering a perfect teamwork between the logical and the intuitive, between the analytical and the creative. The Corpus Callosum, the main nerve bundle or the white matter that joins the two halves, facilitates and synergistically coordinates the communication between these different parts of the brain to ensure the effective functioning of human body. In my view, this is a classic example of teamwork and coordination, created by none other than the Supreme Power to enlighten us.
