Language acquisition is of central importance to child development.Although this developmental trajectory is shaped by experience tc m350 postnatally, the neural basis for language emerges prenatally.Thus, a fundamental question remains: do structural foundations for language in infancy predict long-term language abilities? Longitudinal investigation of 40 children from infancy to kindergarten reveals that white matter in infancy is prospectively associated with subsequent language abilities, specifically between: (i) left arcuate fasciculus and phonological awareness and vocabulary knowledge, (ii) left corticospinal tract and phonological awareness, and bilateral corticospinal tract with phonological memory; controlling for age, cognitive, and environmental factors.Findings link white matter in infancy with school-age language abilities, suggesting that white matter organization in infancy neflintw-r6mpw sets a foundation for long-term language development.
