Explanation:
Detailed explanation-1: -Thus, the first step in neuron production involves increasing the size of the neural progenitor cell population. Neural progenitors are a mitotic population of cells, that is, they can divide to form new cells. Neurons are post-mitotic cells; once formed they are no longer capable of dividing and producing new cells.
Detailed explanation-2: -Early development In a process called neurulation, the neural folds curve upward and fuse to form the neural tube, which will eventually become the CNS.
