Olfactory bulb (accessory) granule cell

Name: Olfactory bulb (accessory) granule cell
Description: The main intrinsic neuron in the accessory olfactory bulb in the mammalian central nervous system. It resembles the granule cell in the main olfactory bulb, including the lack of an axon. Each cell gives rise to short central dendrites and a single long apical dendrite that traverses the granule cell layer, pierces the mitral cell body layer, and branches and terminates within the external plexiform layer among the lateral dendrites of mitral and tufted cells. The dendrites receive synaptic input from mitral and tufted cell dendrites, and have synaptic outputs to those dendrites through reciprocal dendrodendritic synapses. Shepherd, Chen, Greer. Olfactory Bulb. In The Synaptic Organization of the Brain, ed 5. New York: Oxford University Press, 2004. The AOB granule cells are replaced in the adult through ongoing neurogenesis in the subventricular zone

EditorialNoteReplaced Dendritic location "external ple Replaced Dendritic location "external plexiform layer of the AOB" with preferred term "Olfactory bulb (accessory) external plexiform layer" As the curator noted that the cell is found generally in mammal, I replaced "Rat, mouse(generally applies to mammals)" with "Mammal". Note that universality is not implied by this statement, that is, it need not be in all mammals, just some or most mammals. in all mammals, just some or most mammals.
