Research shows how brain flexibility emerges in infants

Publishing their work in the Proceedings of the National Academy of Sciences (PNAS), the researchers show that brain regions with high neural flexibility appear consistent with the core brain regions that support cognitive flexibility processing in adults, whereas brain regions governing basic brain functions, such as motor skills, exhibit lower neural flexibility in adults, demonstrating the emergence of functionally flexible brains during early infancy. The research found that neural flexibility increased with age across the whole brain, and specifically in brain regions that control movement, potentially enabling infants to learn new motor skills.
