Early Neural Timeline
Carnegie Stage	Event
8	(about 18 postovulatory days) neural groove and folds are first seen
9	three main divisions of the brain, which are not cerebral vesicles, can be distinguished while the neural groove is still completely open.
10	(two days later) neural folds begin to fuse near the junction between brain and spinal cord, when neural crest cells are arising mainly from the neural ectoderm
11	(about 24 days) the rostral (or cephalic) neuropore closes within a few hours; closure is bidirectional, it takes place from the dorsal and terminal lips and may occur in several areas simultaneously. The two lips, however, behave differently.
12	(about 26 days) The caudal neuropore takes a day to close. The level of final closure is approximately at future somitic pair 31 (corresponds to the level of sacral vertebra 2). Secondary neurulation begins, is the differentiation of the caudal part of the neural tube from the caudal eminence (or end-bud) without the intermediate phase of a neural plate.
13	(4 weeks) the neural tube is normally completely closed.
