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. öõúùû üüüüüüüüüüüüüüüüüüüüüüüüüüüüüüü1 û 5 4 ß ß ü # % 15,400,000 4,620,000 20,020,000 # Æ % 10,500,000 3,150,000 13,650,000 # ÆÆ% 10,500,000 3,150,000 13,650,000 Øü 36,400,000 10,920,000 47,320,000 +, ±5 >> µ +ß.
