Three Core Concepts in Early Development - Center on the Developing Child at Harvard University

Here is a series of three short videos from the Center on the Developing Child at Harvard University on the early development of the brain. Pretty basic information, but also a nice primer on early neural development.

Three Core Concepts in Early Development

Center on the Developing Child at Harvard University

Healthy development in the early years provides the building blocks for educational achievement, economic productivity, responsible citizenship, lifelong health, strong communities, and successful parenting of the next generation. This three-part video series from the Center and the National Scientific Council on the Developing Child depicts how advances in neuroscience, molecular biology, and genomics now give us a much better understanding of how early experiences are built into our bodies and brains, for better or for worse.

Video #1: Experiences Build Brain Architecture

The basic architecture of the brain is constructed through a process that begins early in life and continues into adulthood. Simpler circuits come first and more complex brain circuits build on them later. Genes provide the basic blueprint, but experiences influence how or whether genes are expressed. Together, they shape the quality of brain architecture and establish either a sturdy or a fragile foundation for all of the learning, health, and behavior that follow. Plasticity, or the ability for the brain to reorganize and adapt, is greatest in the first years of life and decreases with age.

Video #2: Serve & Return Interaction Shapes Brain Circuitry

One of the most essential experiences in shaping the architecture of the developing brain is "serve and return" interaction between children and significant adults in their lives. Young children naturally reach out for interaction through babbling, facial expressions, and gestures, and adults respond with the same kind of vocalizing and gesturing back at them. This back-and-forth process is fundamental to the wiring of the brain, especially in the earliest years.  

Video #3: Toxic Stress Derails Healthy Development 

Learning how to cope with adversity is an important part of healthy development. While moderate, short-lived stress responses in the body can promote growth, toxic stress is the strong, unrelieved activation of the body's stress management system in the absence of protective adult support. Without caring adults to buffer children, the unrelenting stress caused by extreme poverty, neglect, abuse, or severe maternal depression can weaken the architecture of the developing brain, with long-term consequences for learning, behavior, and both physical and mental health.
