The neural plate is a key developmental structure that serves as the basis for the nervous system. Opposite the primitive streak in the embryo, ectodermal tissue .

Neurulation refers to the folding process in vertebrate embryos, which includes the transformation of the neural plate into the neural tube.
With the primary neurulation begins the genesis of the nervous system.
The notochord exercises an inductive effect on the ectoblast that lies above it. It is distinguished by the appearance of columnar cells. In this lecture, we will first consider the induction of the neural plate and the formation of the neural tube, the rudiment of the central nervous system (CNS).

During gastrulation, signals derived from the dorsal mesoderm (organizer) induce the neural plate , making it distinct from the adjacent non-neural ectoderm. The differentiation of the presumptive neural plate , the neural plate and the neural tube have been investigated in the chick embryo by SEM, TEM and . Neural plate definition is – a thickened plate of ectoderm along the dorsal midline of the early vertebrate embryo that gives rise to the neural tube and neural . Other articles where Neural plate is discussed: animal development: Differentiation of the germinal layers: …layer thickens and becomes the neural plate , whose . Early subdivisions in the neural plate define distinct competence for inductive signals. Using three distinct reagents to inhibit Nodal signals, we show that Nodal signalling is required for neural plate patterning across the medial-lateral axis and that, . Numerous overlapping plug grafts were performed upon New-cultured chick . During neurulation, they change shape and produce an infolding of the neural plate (the neural fold) that then seals to form the neural tube. The different domains of cells thus established—epidermis, neural plate and notoplate—. Both cell motility that leads to columnarization of neural plate cells.
Neuron), produced by the nonneural ectoderm at border of the anterior and lateral neural plate , now introduces a novel signaling pathway . Development of the neural plate region at the Week embryonic disc stage. Dorsal view of the embryonic disc from the amniotic cavity side . We show that the movements of cells in the zebrafish neural plate are highly coordinated during the convergence and internalization . REGIONALIZATION OF THE PROSENCEPHALIC NEURAL PLATE. Annual Review of Neuroscience.
As the neural folds form, elevate and fuse to form the neural tube during neurulation, the two populations of NC cells are brought together.
Two organizing centres operate at long-range distances within the anterior neural plate to pattern the forebrain, midbrain and hindbrain. At the beginning of neurulation, the cells of the neural ectoderm thicken to form the neural plate. This thickening is induced by mesodermal .
