ABSTRACT The present study reviews the anatomy of the rodent olfactory bulb and proposes its subdivision along the rostrocaudal axis into five equidistant rostrocaudal levels and the definition of eight topographic locations on each level. This subdivision enables the study of analogous regions when comparing different developmental stages, different experimental conditions or different closely-related species. As examples, we analyze the results for rats and mice describing the patterns of Nissl staining and NADPH-diaphorase histochemical labelling in the olfactory bulb. Different experimental conditions in which the olfactory bulb undergoes size changes are also discussed.
