File:CNS passive.jpg

This is a redrawn diagram illustrating the passive migration of cells after the production of neuron or glial cells in the proliferative zone in the developing CNS. The older cells are displaced outward away from the proliferative zone by the newly produced cells and resulting in an "outside-to-inside" spatiotemporal region.

(A) The first neurons to leave to proliferative zone are shown as triangles. (B) The next neurons formed are shown as diamonds. They move away from the proliferative zones and displace the earlier generated ones. (C) The final neurons are shown as stars. These cells move away from the ventricular zone and displace both earlier generated cells.

V = Ventricular surface; VZ = ventricular zone; IZ = intermediate zone; CP = cortical plate; MZ = marginal zone; P = pial surface
