Verse 1 In the depths of the brain, where the signals ignite, The vagus nerve whispers through day and through night. From gut to the heart, up the brainstem it climbs, To the hypothalamus, syncing in time. Afferent fibers, they carry the call, Triggering hormones that rise and that fall. Oxytocin surges, a bond in the flow, Warmth in the chest, where connections can grow. Pre-Chorus It’s a bridge ‘tween the body and mind, Parasympathetic, so gentle, so kind. Rest and digest, let the tension unwind, Feedback loops spinning, what secrets they’ll find. Chorus Oh, vagus, you’re the wanderer, roaming so free, Boosting oxytocin, setting bonds to be. Vasopressin rises when the signals align, Homeostasis calling, in rhythm divine. Round and round the pathways go, From NTS to PVN, let the hormones flow. Vagus nerve, you’re the key to the door, Unlocking trust, and so much more. Verse 2 For oxytocin, it’s love in the air, Suckling and hugs, vagal paths take us there. Stimulation electric, or a touch so light, Plasma levels climbing, making everything right. But vasopressin? Oh, it’s got its own beat, Anti-emetic guardian, keeping balance sweet. In ferrets or rats, when the afferents fire, It floods like a river, quenching thirst’s desire. Pre-Chorus It’s context that matters, in stress or in calm, VNS therapies, like a healing balm. From addiction to anxiety, the nerve plays its part, Modulating signals straight from the heart. Chorus Oh, vagus, you’re the wanderer, roaming so free, Boosting oxytocin, setting bonds to be. Vasopressin rises when the signals align, Homeostasis calling, in rhythm divine. Round and round the pathways go, From NTS to PVN, let the hormones flow. Vagus nerve, you’re the key to the door, Unlocking trust, and so much more. Bridge Bidirectional whispers, receptors awake, Oxytocin loops back, for connection’s sake. In humans and animals, the story’s the same, Vagal tone tuning the bonding game. Chorus (Outro) Oh, vagus, you’re the wanderer, roaming so free, Boosting oxytocin, setting bonds to be. Vasopressin rises when the signals align, Homeostasis calling, in rhythm divine... (fade out)
