1 Formation of the neural tube consists of 3 successive stages of development. 2  THE NEURAL PLATE results from thickening and differentiation of ectoderm overlying the notochord.3  The ectoderm of the plate is called neuroectoderm and will give rise to the central nervous system, consisting of the brain and spinal cord. The neural crests: when the neural folds fuse and, before the neural groove closes completely, some neuroectodermal cells detach themselves from the region where the neural tube borders on the ectoderm (lateral edges of the neural plate).
