The Pathway For The Laminae

Ixchel (Informed)

As Lamina breathes in Ixchel is transformed the Neural pathways, the informed state goes to two different destinations. A world for the Lumine and a world for the Laminae. 

The neural tube is the embryonic structure that ultimately forms the central nervous system (CNS)—that is, the brain and spinal cord. It is one of the most critical structures in early development.

The neural tube develops from the neural plate, which is a thickened region of neuroectoderm

Neural induction signals from the notochord and organizer region (e.g., BMP inhibitors) cause ectodermal cells to become neural plate cells.

Formation process: neurulation

Neural plate formation – the neuroectoderm thickens along the dorsal midline

Neural groove formation – the center of the neural plate folds inward

Neural folds elevate – lateral edges of the plate rise

Neural tube closure – folds fuse at the midline, forming a hollow tube

Structure of the neural tube:

Neuroepithelial cells line the tube’s inner cavity (ventricular zone)

Patterning within the neural tube:

neural tube is patterned along two main axes:

Anterior–posterior (rostral–caudal)

Signals like FGFs, Wnts, retinoic acid determine brain vs spinal cord identity

Ventral (floor plate) → (Shh) → motor neurons

Dorsal (roof plate) → BMPs/Wnts → sensory neurons

Ectoderm → neural plate → neural groove → neural tube → brain & spinal cord
