Cerebral cortex - Development
The cerebral cortex develops from the neural plate, a specialised part of the embryonic ectoderm. The neural plate folds and closes to form the neural tube. From the cavity inside the neural tube develops the ventricular system, and from the epithelial cells of its walls, the neurones and glial cells. The most frontal part of the neural tube, the telencephalon gives rise to the cerebral hemispheres and the neocortex.
Most cortical neurones are generated within the ventricular zone close to the ventricles. Initially, progenitor cells in the ventricular zone divide symmetrically, producing two progenitor cells by mitotic cycle. Then, some progenitor cells begin to divide asymmetrically, producing one postmitotic cell that migrates and leaves the ventricular zone, and a daughter cell that continues to divide or that eventually dies. The postmitotic cells will become neurones.

Sneak-Peek of Global Oneness Community
Hi friend! The Global Oneness Community, the place for information and sharing about Oneness is not really launched yet (you will see there is still some clean up to do) ...but it is now open for a sneak-peek! And if you wish - please register and become one of the very first members to do so! Jonas
