File:CNS active.jpg

This is a redrawn diagram illustrating the active migration of cells after the production of neuron or glial cells in the proliferative zone in the developing CNS. The later-generated cells bypass the earlier-generated cells and result in a location further away from the proliferative zone, resulting in an "inside-to-outside" spatiotemporal gradient. (A) The first neurons to leave to proliferative zone are shown as triangles and they form a corticle plate between the intermediate and the marginal zones. (B) The next neurons formed are shown as diamonds. They leave the proliferative zones, migrate across the intermediate zone to the top of the cortical plate by passing the first neurons. (C) The final neurons are shown as stars. The cells also migrate to the top of the cortical plate. V = Ventricular surface; VZ = ventricular zone; SZ = subventricular zone; IZ = intermediate zone; CP = cortical plate; MZ = marginal zone; P = pial surface
