Morphogenesis
... The neural plate begins to fold, forming the neural groove. Closure to form the neural tube begins in the future midbrain region, and then extends cranially and caudally. Neural crest cells migrate away from the site of closure and later take numerous roles within the body, forming peripheral neuron ...

Subventricular zone
The subventricular zone (SVZ) is a paired brain structure situated throughout the lateral walls of the lateral ventricles. It is composed of four distinct layers of variable thickness and cell density, as well as cellular composition. Along with the dentate gyrus of the hippocampus, the SVZ is one of two places where neurogenesis has been found to occur in the adult mammalian brain.
