White Matter
White Matter
White matter is brain tissue made up of bundles of nerve fibers that connect different regions of the brain, appearing white because they are wrapped in a fatty substance called myelin.
Details
White matter refers to the areas in the brain and spinal cord densely packed with axons — the long projections of nerve cells — which are wrapped in a fatty substance called myelin (the myelin sheath), giving them their characteristic white appearance.
What Does White Matter Do?
Mindy is here to help you understand. If the brain's gray matter is the 'computer chip' that processes information, then white matter is the 'cable' connecting all those chips together. It helps the brain's many regions communicate quickly and accurately with one another.

White Matter and Mental Health
A Warm Word from Mindy
White matter is the precious connective tissue that allows our brain to work together as one unified team. Regular aerobic exercise, a healthy diet, sufficient sleep, and activities that involve learning new things all help maintain the health of your white matter.
💡 Real-Life Example
If you practice piano consistently, the white matter connecting the brain regions involved in finger movement becomes strengthened, and you may notice yourself becoming noticeably more skilled over time.
