| Research Abstract |
To understand the significance of adult neurogenesis, we genetically ablated newly born neurons in the adult mouse brain. Mutant mice showed defects in predator odor avoidance. Furthermore, mutant males displayed deficits in male-male aggression and sexual behaviors toward females, while mutant females displayed deficits in fertility and nurturing. These results suggest that adult neurogenesis plays an essential role in predator avoidance and gender-specific responses that are olfactory-dependent and innately programmed.
