Molecular genetics of neurulation.

Ciba Foundation symposium, 1994
The formation of the neural tube begins during gastrulation when ectoderm, an epithelial sheet on the outside of the embryo, is induced to form the neural plate. During the process of neural induction, the epithelium of the neural plate is regionalized along both the dorsoventral and anteroposterior axes of the embryo; this regionalization is likely to

Glycoconjugates in normal and abnormal secondary neurulation

Teratology, 1995
AbstractIn chick embrayos, the anterior greater portion of the neural tube develops by the folding, apposition, and fusion of the neuroectoderm. The smaller caudal portion that forms the secondary neural tube (lumbosacral and coccygeal regions) is derived from the tail bud, an aggregate of mesenchymal cells located at the caudal limit of the body. Tail

Multi-inference with Multi-neurules

2002
Neurules are a type of hybrid rules combining a symbolic and a connectionist representation. There are two disadvantages of neurules. The first is that the created neurule bases usually contain multiple representations of the same piece of knowledge. Also, the inference mechanism is rather connectionism oriented than symbolism oriented, thus reducing ...

Neurulation and Neural Tube Defects

2014
Neurulation has been extensively studied in amphibian, avian and mammalian embryos and occurs in four stages: formation of the neural plate, shaping of the neural plate, bending of the neural plate and closure of the neural groove. The rostral part of the neural tube develops into the brain, whereas the caudal part becomes the spinal cord.

Development of the Ectoderm: Neurulation

1971
The principal derivative of the ectoderm is nervous tissue or neural ectoderm. Its differentiation constitutes neurulation. The rest of the ectoderm is then called surface ectoderm.

Normal neurulation in amphibians.

Ciba Foundation symposium, 1994
How does cell behaviour accomplish neurulation in amphibian embryos? During neurulation, the neural plate (while preserving the same volume) doubles its length, triples its thickness, narrows 10-fold, greatly decreases its surface and rolls into a tube. Cells that compose the neural plate produce these changes in three ways.

MECHANISTIC INSIGHTS INTO SECONDARY NEURULATION

2009
The central nervous system is formed by a series of movements referred to as neurulation. There are two modes of neurulation, known as primary and secondary neurulation. Primary neurulation occurs in anterior regions and involves an epithelial folding process.
