In this episode, we explore Oxytocin and Vasopressin's vast roles in Human Biology. We time travel to cover the evolution of the two molecules and learn about their functions with developing and socializing. Oxytocin and Vasopressin are dynamic molecules whereby they are Peptides and Hormones. In addition, we cover previously discussed brain regions and how the molecules work alongside key Neuromodulators like Serotonin and Dopamine.
