چکیده انگلیسی


• Pup-induced parental behavior by non-reproductive animals requires brain adaptations.
• Male/female alloparental care is common in group-living species with cooperative care.
• High oxytocin receptors in the nucleus accumbens is associated with alloparental care.
• Male alloparental care might predict oxytocin receptor density in the nucleus accumbens.

Parental behavior is commonly displayed by progenitors. However, other individuals, genetically related (e.g. siblings, aunts, uncles) or not with the newborns, also display parental behavior (commonly called alloparental, or adoptive behavior). I hypothesize that species that live in family or social groups where other non-reproductive members (males and females) take care of infants, have brain adaptations to promote or facilitate that behavioral response. The present work revises the evidence supporting the hypothesis that high density of oxytocin receptors (OXTR) in the nucleus accumbens (NA) is one of those adaptations. All species known to have high NA OXTR show not only female, but also male alloparental care. Therefore, I predict that high NA OXTR could be present in all species in which juvenile and adult male alloparental behavior have been observed. Strategies to test this and other alternative working hypothesis and its predictions are presented.
