Abstract

- The neuropeptide oxytocin plays a prominentrole in social and emotional cognition. Findings suggest that exogenous intranasal oxytocin administration facilitates emotion recognition in humans, but individual and contextual differences may have moderating effects. A major caveat in this line of work is that it is predominantly based on young males, which limits current knowledge and potential for generalizability across gender. To uncover potential gender effects, the present study included younger and older men and women. Utilizing a randomized, double-blind, placebo-controlled, within-subjects study design, we investigated the effects of a single-dose of 40 IUs intranasal oxytocin administration on emotion recognition of dynamic positive and negative stimuli in 32 men (mean age 45.78, sd. 22.87) and 39 women (mean 47.87, sd. 47.87), 40 minutes prior to MRI scanning. Preliminary analyses show that oxytocin induced brain activity reductions during exposure to negative (relative to positive) stimuli in women, while increasing brain activity in dorsomedial prefrontal cortex in men. We speculate that the effects of oxytocin on emotion recognition may possibly be related to emotion regulation and mentalization processes, and that oxytocin is related to potential sex-differences in these processes. The results also raise concern that previous oxytocin literature on emotion recognition may be biased as there appears to be gender-differential effects of oxytocin on brain activity across adulthood that have been underestimated. In the next stage of the present study, we will investigate the interaction effects among treatment, sex, age, and presentation modality.
