What This Study Did, in Plain Language
What Was Tested
The paper reports a study of Oxytocin, published as a randomized controlled trial.
The current randomized, double-blind, placebo-controlled neuropsychopharmacological functional magnetic resonance imaging experiment was conducted in 147 healthy participants (OXT = 74, men/women = 37/37; placebo = 73, men/women = 36/37) to examine the oral OXT effect on plasma OXT concentrations and neural response to emotional scenes in both sexes.
Why It Was Studied
Sex differences are shaped both by innate biological differences and the social environment and are frequently observed in human emotional neural responses.
However, it is unclear whether oral OXT produces similar sex-dependent effects on processing continuous emotional scenes.
Who Took Part
The study group was 147 participants.
By PubMed's age tags, the people studied were young adults and adults, both men and women.
How the Study Was Run
The researchers set it up as a randomized, double-blind and placebo-controlled study.
The participants were allocated by chance, so the Oxytocin group and the comparison group should start out alike.
Blinding on both sides kept the participants and researchers unaware of who received Oxytocin.
Some participants received a placebo instead of Oxytocin, giving a reference point.
What Was Measured
PubMed files the paper under topics including Oxytocin, Amygdala, Magnetic Resonance Imaging, Emotions, Sex Characteristics and Insular Cortex.
Author keywords: Emotional processing, Functional magnetic resonance imaging, Multivariate pattern analysis, Oral oxytocin and Sex difference.
