Most of what we know â€” or think we know â€” about how kids learn comes from classroom practice and behavioral psychology. Now, neuroscientists are adding to and qualifying that store of knowledge by studying the brain itself.

Nearly two decades ago, a massive wave struck the Tokio Express, a container ship that had nearly 5 million Legos onboard. The colorful toy building blocks poured into the ocean. Today, they are still washing up on shores in England.
