Term

central nervous system formation

ID (Ontology)

GO:0021556 (Gene Ontology)

Definition

The process that gives rise to the central nervous system. This process pertains to the initial formation of a structure from unspecified parts. The central nervous system is the core nervous system that serves an integrating and coordinating function. In vertebrates it consists of the brain, spinal cord and spinal nerves.
