Schematic of the<unk>  as related to the Protomap Hypothesis (colored regions) of cortical development and evolution. Adapted from Rakic, 1995, 2009. VZ, ventricular zone; SVZ, subventricular zone; IZ, intermediate zone; SP, subplate; CP, cortical plate; MZ, marginal zone; RG,<unk>  glia; MN, migrating neuron; TR, thalamic<unk> ion; CC, cortico-cortical axons. E## represents post-conceptional age of macaque monkey. The<unk>  (RUH) is a conceptual theory of cerebral cortex development, first described by Pasko Rakic. The RUH states that the cerebral cortex develops during embryogenesis as an array of interacting cortical columns, or<unk> <unk> s', each of which originates from a transient stem cell layer called the ventricular zone, which contains neural stem cells known as<unk>  glial cells.
