Quizplus · Accepted Answer

The increase in white matter in the brain from childhood to middle age is attributed to the continued growth of myelin. Myelin is a fatty substance that covers and insulates the axons of neurons, and it is essential for the efficient transmission of signals within the brain. As we age, myelin continues to grow in density and thickness, leading to an increase in white matter volume in the brain.
