Neurodevelopment is a complex process that starts in humans as early as the second gestational week with neurulation
and continues through adolescence (Rice and Barone 2000).
Neural tube defects (NTDs) are multifactorial midline abnormalities that occur during the neurulation
process in embryogenesis.
These specialized cells arise at the time of neurulation
and migrate to their target sites in the body, where they give rise to very different cell types such as sensory neurons, glia, melanocytes, adrenal medulla and cranial cartilage/bones.
Cell surface beta 1,4-galactosyltransferase functions during neural crest cell migration and neurulation

Strategies of vertebrate neurulation
and a re-evaluation of teleost neural tube formation.
Cadmium exposure during neurulation
induces a higher incidence of neural tube defects (Robenson et al.
35) Claudins were started to express in epiblast after neurulation
and also expressed in endoderm (24) and liver.
Currarino syndrome is caused by abnormality in the canalization and retrogressive differentiation of caudal cell mass formed by secondary neurulation
INTRODUCTION: Development of central nervous system is a highly complicated process and is organized in the following steps: Primary neurulation
starts at 3-4 weeks of gestation, followed by prosencephalic development occurs at 2-3 months of gestation, neuronal proliferation starts at 3-4 months of gestation, and neuronal migration at the age of 3-5 months, followed by organization starts from 5 months of gestation to birth, and myelination after the birth will occur.
Neural tube defects--disorders of neurulation
and related embryonic processes.
Completion of implantation, gastrulation, and neurulation
are discussed before an interlude on, first, the mechanisms of normal and misdirected morphogenesis, and second, a general overview of fetal development and fetal healthcare needs.
