Figure 2: Schematic presentation of interkinetic nuclear movements in the ventricular zone (VZ). Nuclei of RGC are found at the upper surface of the VZ during S phase (S). The nuclei of the cells undergoing mitosis (M phase) are located close to the ventricle, where they complete anaphase (A) and telophase (T). Nuclei in G1 and G2 phases are found in intermediate positions.
