Organization of AON circuitry

AON pars externa, the intrabulbar associational system and topography in the olfactory system 

The radial or laminar organization of the non-pE AON system may relate to a proposed plan of radial or laminar organization between mitral and tufted cells and granule cells. As reviewed earlier, the lateral dendrites of different mitral cells preferentially arborize at a particular depth of the EPL. The dendrites of some mitral cells arborize in the deeper parts of the EPL just above the mitral cell layer while the lateral dendrites of other mitral cells preferentially arborize more superficially in the EPL. The apical dendrites of granule cells located in the superficial part of the GCL arborize in
