- The neural plate is a key developmental structure that serves as the basis for the nervous system1. It is formed when ectodermal tissue thickens and flattens to become the neural plate, cranial to the primitive node of the embryonic primitive streak1. The neural plate is the source of the majority of neurons and glial cells of the CNS2. The neural groove forms along the long axis of the neural plate, and the neural plate folds to give rise to the neural tube2. When the tube is closed at both ends it is filled with embryonic cerebrospinal fluid2.

Wikipedia text under CC-BY-SA license Development of the nervous system - Wikipedia
The vertebrate central nervous system (CNS) is derived from the ectoderm—the outermost germ layer of the embryo. A part of the dorsal ectoderm becomes specified to neural ectoderm – neuroectoderm that forms the neural plate along the dorsal side of the embryo. This is a part of the early patterning of the embryo (including the invertebrate embryo) that also establishes an anterior-posterior …
