Used primarily in research to study the physiological effects of vasotocin-like peptides in various species. It helps in understanding the role of similar hormones in regulating water balance, blood pressure, and reproductive behaviors. Often applied in neuroendocrinology and comparative physiology to explore its impact on social and mating behaviors, particularly in non-mammalian vertebrates. Also utilized in laboratory settings to investigate its potential as a model for studying human vasopressin and oxytocin systems.
