Females are more likely to suffer from stress-related conditions that impact socioemotional behavior compared to males. One thing that influences how sex impacts stress-related health problems is social dominance. We examined whether there are sex differences in the effects of social dominance on socioemotional behavior in socially housed rhesus monkeys. Because the neurotransmitter serotonin is important for socioemotional behavior, we also looked at the levels of the 5HT1AR receptor using neuroimaging. Aggression was greater in dominant compared to subordinate animals, and submission was significantly greater in subordinate versus dominant animals and greater in females than males. Anxiety and levels of 5HT1AR in the hypothalamus were significantly greater in females than in males. 5HT1AR in the hippocampus was greater in dominant compared to subordinate females but was not different between dominant and subordinate males. Overall, these data are important for the treatment of stress-related behavioral health outcomes because suggest that sex and social dominance are important factors to consider in the context of how effective drugs targeting the serotonin system are for treating stress-related behavioral health conditions.
