Early Brain Development and Public Health.

Early brain development research is important to public health professionals for understanding early development and strengthening systemic supports for young children's healthy brain growth. This overview describes basic processes of early brain development, including prenatal development and the "fetal programming" of brain and behavior, neural proliferation and the essential influence of experience in the creation of neural networks, the maturational timing of different brain systems and their behavioral consequences, the myelination of neural pathways and its influence on children's action and thinking, and the capacity of the brain to create new neural connections throughout life, which contributes to its continuing adaptability to new experiences. The implications of this research for public health and for strengthening support for early brain development are considered throughout this discussion.
