We know that responsive relationships and language-rich experiences for young children help build a strong foundation for later success in school. The rapidly advancing frontiers of 21st-century biological sciences now provide compelling evidence that the foundations of lifelong health are also built early, with increasing evidence of the…

It is the belief of the National Scientific Council on the Developing Child that better public understanding of the rapidly growing science of early childhood and early brain development can provide a powerful impetus for the design and implementation of policies and programs that could make a significant difference in the lives of all children.…

This science brief reports on a study that identified the effects of different experiences on critical periods of learning during early brain development. The study found that the presence of corticosterone in a part of the brain called the amygdala determined whether a normally painful experience was learned as an attractive or fearful event.…

Recent advances in neuroscience show clearly how experience can change brain neurochemicals, and how this in turn affects the way the brain functions. As a result, early negative events actually get built into the growing brain's neurochemistry, altering the brain's architecture. Research is continuing to investigate how children with genetic…
