Like every1 said notochord is from mesoderm. Notochord induces the formation of spinal cord but spinal cord itself is formed from neural tube which arises from the ectoderm.
notochord gives rise to the vertebrate backbone or spinal chord backbone, it is bone so it is mesoderm...nerve cord or neural tube arises from the ectoderm and thus develops into the CNS (central nervous system). hope that helps

CNS itself includes brain + spinal cord, so yes neural tube gives rise to both brain and spinal cord. Notochord doesn't form spinal cord, it just helps neural tube in spinal cord formation.
In addition to the above posts, the notochord turns into the vertebrate in HIGHER chordates while in LOWER chordates, the notochord is the basis of support.
