Social selectivity and social motivation in voles

Selective relationships are fundamental to humans and many other animals, but relationships between mates, family members, or peers may be mediated differently. We examined connections between social reward and social selectivity, aggression, and oxytocin receptor signaling pathways in rodents that...

description	Selective relationships are fundamental to humans and many other animals, but relationships between mates, family members, or peers may be mediated differently.
