When it comes to communication skills—maybe we’re born with it?

A study by Boston University researcher Jennifer Zuk found that the brain's organizational pathways, known as white matter, set a foundation for language learning abilities within the first year of life. This is reflected in children born with higher indications of white matter organization having better language skills five years later.
