Development of the nervous system Development of the nervous system refers to the processes that generate, shape, and reshape the nervous system of animals, from the earliest stages of embryogenesis to adulthood. The field of neural development draws on both neuroscience and developmental biology to describe and provide insight into the cellular and molecular mechanisms by which complex nervous systems develop, from the nematode and fruit fly to mammals.
