Changes

Development of the brain begins with a series of expansions of the neural tube at the cranial end, giving rise to the internal spaces of the brain, the ventricles and aqueducts. The initial expansion of the neural tube is in the mesencephalon area, or mid brain area. This is then followed by expansions in the rhombencephalon (hind brain) and in the proencephalon (forebrain).
