Question

Quizplus · Accepted Answer

The prefrontal cortex undergoes rapid myelination and synaptic formation and pruning during the preschool and school years, which is important for higher-order cognitive functions like attention, working memory, decision making, and social cognition. While some myelination and synaptic pruning continue into early adulthood, it is not as rapid or pronounced as during the early childhood years. Myelination in the prefrontal cortex does not typically occur in midlife or beyond.
