Whereas vasopressin (AVP) neurons in the PVN are sympathoexcitatory, and activation of vasopressin receptors inhibits cardioinhibitory parasympathetic cardiac vagal neurons (CVNs) [6], recent work has shown activation of oxytocin receptors can be cardioprotective and reduces the adverse cardiovascular consequences of anxiety and stress [7], [8], [9]. Here, OXTR is linked to Anxiety.
