From neurons to neighborhoods: old and new challenges for developmental and behavioral pediatrics.

Rapidly advancing research in neurobiology and the behavioral and social sciences, coupled with dramatic changes in the social and economic circumstances under which families are raising young children, has created a highly dynamic context for early childhood policy, service delivery, and child rearing in the United States. A recent report from the National Research Council and the Institute of Medicine, presents a critical analysis of that complex knowledge base and a set of recommendations designed to close the gap between what we know and what we do to promote the healthy development of young children. This article examines the report through the lens of developmental and behavioral pediatrics and highlights both exciting opportunities and sobering challenges.
