During early development of the vertebrate embryo, a longitudinal groove on the neural plate gradually deepens and the ridges ... The neural tube gives rise to both brain and spinal cord. The anterior (or 'rostral') portion of the neural tube initially ... formation of the neural tube is called neurulation. At this stage, the walls of the neural tube contain proliferating neural ...
They fold, along a shallow neural groove which has formed as a dividing median line in the neural plate. This deepens as the ... Neurulation refers to this folding process whereby the neural plate is transformed into the neural tube, and this takes place ... The neural plate that has formed as a thickened plate from the ectoderm, continues to broaden and its ends start to fold ... This is enabled by the folding of the embryo which pushes the tubes into the thoracic cavity. Also at the same time that the ...

These two grooves in the neural folds transform into optic vesicles with the closure of the neural tube. The optic vesicles ... Development of the optic vesicles starts in the 3-week embryo, from a progressively deepening groove in the neural plate called ... Several layers such as the neural tube, neural crest, surface ectoderm, and mesoderm contribute to the development of the eye. ... The eye is essentially a derivative of the ectoderm from the somatic ectoderm and neural tube, with a succession of inductions ...
In embryonic development, all mammalian brains begin as smooth structures derived from the neural tube. A cerebral cortex ... The gyri are part of a system of folds and ridges that create a larger surface area for the human brain and other mammalian ... with deepening indentations and ridges developing on the surface of the cortex. Changes in the structure of gyri in the ... It is generally surrounded by one or more sulci (depressions or furrows; SG: sulcus). Gyri and sulci create the folded ...
