The role of neurogenesis in olfaction-dependent behaviors

Newly born neurons continuously migrate into the main and accessory olfactory bulbs and modulate the output of projection neurons. Despite some contradictory results, it is becoming clear that these newly born neurons play an important role in the response to some odorant cues. In this minireview, we discuss the recent findings surrounding the functional significance of adult neurogenesis in olfaction-dependent behaviors.

► Adult neurogenesis is important for olfaction-dependent behaviors.
► Discrepancies exist among the published reports of the roles of adult neurogenesis.
► The significance of adult neurogenesis should be examined by using various methods.
