Neuronal Chain Gangs: Homotypic Contacts Support Migration into the Olfactory Bulb
face of the brain and across the paths of radial glia, the orientation of their movements is defined as tangential. Stanford, California 94305 Some classes of migrating neurons in other areas of the developing brain are found in close apposition to axon A great deal of attention in the field of developmental neurobiology is presently focused on the rodent olfac-tracts and appear to use an axono...
متن کاملNeuronal migration from the forebrain to the olfactory bulb requires a new attractant persistent in the olfactory bulb.
Interneurons in the olfactory bulb (OB) are generated not only in the developing embryo but also throughout the postnatal life of mammals from neuronal precursor cells migrating from the anterior subventricular zone (SVZa) of the mammalian forebrain. We discovered that the OB secretes a diffusible activity that attracts these neuronal precursor cells. The attractive activity is present in speci...
متن کاملNeuronal organization of olfactory bulb circuits
Olfactory sensory neurons extend their axons solely to the olfactory bulb, which is dedicated to odor information processing. The olfactory bulb is divided into multiple layers, with different types of neurons found in each of the layers. Therefore, neurons in the olfactory bulb have conventionally been categorized based on the layers in which their cell bodies are found; namely, juxtaglomerula...
متن کاملAbnormal neuronal migration changes the fate of developing neurons in the postnatal olfactory bulb.
Neuronal precursors are continuously integrated into the adult olfactory bulb (OB). The vast majority of these precursor cells originates from the subventricular zone and migrates along the rostral migratory stream (RMS) en route to the OB. This process, called postnatal neurogenesis, results from intricate pathways depending both on cell-autonomous factors and extrinsic regulation provided by ...
متن کاملExtracellular signals that regulate the tangential migration of olfactory bulb neuronal precursors: inducers, inhibitors, and repellents.
Neuronal migration is an essential developmental step in the construction of the vertebrate nervous system, but the extracellular signals involved in initiating and regulating neuronal movement remain unclear. Here we report the identification of a novel astrocyte-derived migration-inducing activity (MIA). Using an in vitro assay, we show that MIA induces the migration of olfactory bulb interne...
