1. The apical surface area increases during neurulation , unlike amphibian embryos. 2. The formation of the neural tube from the ectoderm is called neurulation . 3. Later in development, neurulation causes the neurectoderm to form the neural tube. 4. Both chordin and epidermis specified tissue into neural tissue ( see neurulation ). 5. Additionally, she developed an in vitro model of early human neurulation events. 6. Pigment precursor cells ( gray circles ) remain equivalent until they align after neurulation . 7. A similar protein in mice is required for proper neurulation , and gut development. 8. During early embryonic development, paracrine / juxtacrine signaling of hCG induces blastulation and neurulation . 9. The sequence of stages from neural plate to neural tube and neural crest is known as neurulation . 10. Some evidence suggests memory is actually responsible for carrying out the development of the CNS during neurulation .
