Circuitry regulation of adult neurogenesis in the lateral ventricles and olfactory bulb (OB). (A) A sagittal section view of an adult rodent brain highlighting the lateral ventricles and OB. Also shown are the potential axonal projection to the OB. AON, anterior olfactory nucleus; PCTX, piriform cortex; hDB, horizontal limb of the diagonal band of Broca; RN, raphe nucleus; LC, locus coeruleus. (B) Potential inputs to subventricular zone/rostral migratory stream (SVZ/RMS) progenitors and OB interneurons. Color boxes indicate the laminar distribution of the axon terminals of these inputs. GL, glomerular layer; EPL, external plexiform layer; MCL, mitral cell layer; GCL, granule cell layer. (C) Integration of newborn neurons during adult OB neurogenesis. Shown is the summary of various inputs that appear in granule cells (GCs) and periglomular cells (PGCs) in the OB during adult neurogenesis at distinct developmental stages. OSN, olfactory sensory neuron; ETC, external tufted cells; SAC, short-axon cells.
