Question

Quizplus · Accepted Answer

Young brains are more plastic and sensitive to external stimulation partly because they have less myelin. Myelin is a fatty substance that insulates axons, speeding up signal transmission. Less myelin means slower signal transmission, allowing for more plasticity as the brain develops and learns from the environment.
