Are These Hormones the Key to Autism, Schizophrenia?
[Source: Medical News Today]
In a new study, investigators at the University of Pennsylvania in Philadelphia turned to rhesus macaques to investigate the effects of two hormones — oxytocin and vasopressin — on social behavior.
These primates are known for their aggressive, competitive behavior in groups that are highly hierarchized — which typically split members between dominant and submissive individuals.
But rhesus macaques were also chosen for another reason; according to the researchers involved in the recent study, these primates — like humans — live in large social groups, form long-term connections, and present some similar social behaviors.
