Wikipedia
Neuroblast
In vertebrates, a neuroblast or primitive nerve cell is a postmitotic cell that does not divide further, and which will develop into a neuron after a migration phase. In invertebrates such as Drosophila, neuroblasts are neural progenitor cells which divide asymmetrically to produce a neuroblast, and a daughter cell of varying potency depending on the type of neuroblast. Vertebrate neuroblasts differentiate from radial glial cells and are committed to becoming neurons. Neural stem cells, which only divide symmetrically to produce more neural stem cells, transition gradually into radial glial cells. Radial glial cells, also called radial glial progenitor cells, divide asymmetrically to produce a neuroblast and another radial glial cell that will re-enter the cell cycle.This mitosis occurs in the germinal neuroepithelium (or germinal zone), when a radial glial cell divides to produce the neuroblast. The neuroblast detaches from the epithelium and migrates while the radial glial progenitor cell produced stays in the lumenal epithelium. The migrating cell will not divide further and this is called the neuron's birthday. Cells with the earliest birthdays will only migrate a short distance. Those cells with later birthdays will migrate further to the more outer regions of the cerebral cortex. The positions that the migrated cells occupy will determine their neuronal differentiation.

neuroblast
A neuroblast is a type of stem cell from which the neurons of the nervous system are produced. They represent an intermediate stage in cell differentiation, being derived from neuroepithelial cells and giving rise to mature neurons. They play a crucial role in the growth and development of the nervous system in both vertebrates and invertebrates.

Neuroblast
A neuroblast is a dividing cell that will develop into a neuron often after a migration phase. Neuroblasts differentiate from neural stem cells and are committed to the neuronal fate. The main difference between a neuroblast and a neuron is the ability to divide; neuroblasts can still undergo mitosis, whereas neurons are postmitotic. Neuroblast are mainly present as precursor of neurons during the embryonic development. They are also described as one of the cell type of adult neurogenesis, a process that occurs in the adult mammalian brain. They migrate throughout the whole brain and differentiate into olfactory bulb interneurons. Those neuroblasts have been extensively characterized as they could represent a way to achieve brain regeneration if redirected to sites of lesion. In humans, neuroblasts produced by stem cells in the adult subventricular zone migrate into damaged areas after brain injuries. However, they are restricted to the subtype of small interneuron-like cells, and it is unlikely that they contribute to functional recovery of striatial circuits. The characterisation of neuroblasts and their development in Drosophila melanogaster was widely achieved by Chris Doe, Corey Goodman and Mike Bate.
