Abstract

The accessory olfactory bulb (AOB) is a sexually dimorphic structure of the vomeronasal system, which plays a role in the control of sexual behaviors. In adult rats, we have demonstrated previously that the migrating neuroblasts of the subependymal layer (SEL) directed to the main olfactory bulb (MOB) also reach the AOB. To tackle the relation between sexual dimorphism and targeted cell migration, we quantified the neo-neurogenesis in the AOB of adult rats of both sexes. Our results confirm a morphological sexual dimorphism in the AOB granular layer volumes. We showed that the number of newly generated cells reaching the AOB in both sexes was considerable, even if lower than those directed to the MOB. Moreover, we demonstrated that the rate of neurogenesis in the anterior AOB of the two sexes was significantly different.
