Human<unk> . From a paper by Oscar Arias-Carrión, 2008 In an embryonic rat brain, GAD67-binding marker tends to concentrate in<unk> . An image from Popp et al., 2009. The<unk>  <unk>  is a region situated on the outside wall of each lateral ventricle of the vertebrate brain. It is present in both the embryonic and adult brain. In embryonic life, the<unk>  refers to a secondary proliferative<unk>  containing neural progenitor cells, which divide to produce neurons in the process of neurogenesis. The primary neural stem cells of the brain and spinal cord, termed radial glial cells, instead reside in the ventricular<unk>  (VZ) (so-called because the VZ lines the inside of the developing ventricles). In the developing cerebral cortex, which resides in the dorsal telencephalon, the<unk>  and VZ are transient tissues that do not exist in the adult. However, the<unk>  of the ventral telencephalon persists throughout life. The adult<unk>  is composed of four distinct layers of variable thickness and cell density as well as cellular composition. Along with the dentate gyrus of the hippocampus, the<unk>  is one of two places where neurogenesis has been found to occur in the adult mammalian brain. Adult<unk>  neurogenesis takes the form of neuroblast precursors of interneurons that migrate to the olfactory bulb through the rostral migratory stream. The<unk>  also appears to be involved in the generation of astrocytes following a brain injury.
