Neural Development
The complex biological process through which the nervous system grows, matures, and forms functional neural circuits that enable cognitive capabilities and behavioral functions.
Overview
Neural development represents the fundamental biological process underlying cognitive and behavioral capabilities, encompassing the growth, organization, and refinement of neural circuits from early embryonic stages through adolescence and beyond. This process provides the physical substrate for brain maturation and enables the emergence of cognitive development.
