They are formed, from the outer layer of the three basic layers of the embryo (ectoderm, endoderm, and mesoderm in between) present in the first 10 days after the ovum fertilization...
It is quite curious, that the most evolutionized and specialized cells in our body, come fromthe very same layer that produce skin in the future human being...
The answer is ECTODERM layer of the embryo (the most superficial or backwards, depends on how you put it)

from the ectorderm. this is where the neural crest forms in early development. Neurons and most organs of the nervous system come from here.
