The ectoderm is the outermost layer in the early embryo and is responsible for forming the nervous system as well as the skin and hair. This means that the precursor to the cells that will compose the nervous system would be found in the ectoderm layer. The blastula is an early stage of development before gastrulation, and while the endoderm and gastrula are important in forming other structures in the body, they would not be the precursor to the nervous system.
