Physiological correlates of endogenous oxytocin concentrations
Oxytocin’s psychological functions make this neuropeptide an interesting target for biomarker research on mental disorders. Besides measuring the psychological effects of intranasal oxytocin administration, endogenous oxytocin concentrations are a frequently used tool to assess possible neuroendocrine dysregulations related to mental disorders. However, endogenous concentrations do not directly reflect central availability of this peptide. Moreover, they are influenced by various physiological and psychological factors, which we investigated in two meta-analyses.
