Neurogenesis in G minor

Anne-Marie Marzesco , Felipe Mora-Bermudez & Wieland B Huttner

The number of neurons generated during embryonic development of the mammalian cerebral cortex depends on the number and kind of divisions that neural progenitors undergo. The initial neural progenitors, the neuroepithelial cells and the related radial glial progenitors derived from them are highly elongated cells with pronounced apical-basal polarity whose cell bodies occupy the ventricular zone.
