Show moreMultiple and rapid changes in brain development occur in infancy and early childhood that undergird behavioral development in core domains. The period of adolescence also carries a second influx of growth and change in the brain to support the unique developmental tasks of adolescence. This special section documents two core conclusions from multiple studies. First, evidence for change in brain-based metrics that underlie cognitive and behavioral functions are not limited to narrow windows in development, but are evident from infancy into early adulthood. Second, the specific evident changes are unique to challenges and goals that are salient for a respective developmental period. These brain-based changes interface with environmental inputs, whether from the child's broader ecology or at an individual level.The title for this Special Section is The Developing Brain: Evidence for Plasticity during Childhood and Adolescence, edited by Amanda E.
