Oxytocin is a synthetic nine–amino-acid cyclic neuropeptide (a disulfide-bridged nonapeptide). Research has focused on oxytocin-receptor (OXTR) signaling, neuropeptide modulation, and social-behavior neuroscience models.

Oxytocin is investigated in receptor-binding studies, neuroendocrine signaling research, and behavioral-neuroscience models — all in controlled laboratory settings.
