Vagus Nerve Stimulation

Meaning

Vagus Nerve Stimulation (VNS) is a therapeutic technique that involves the electrical or mechanical activation of the vagus nerve, the tenth cranial nerve and the primary component of the parasympathetic nervous system. This stimulation is used clinically to modulate autonomic nervous system balance, which is crucial for regulating heart rate, digestion, mood, and immune response. VNS is recognized for its ability to enhance the body’s innate ability to shift from a sympathetic “fight-or-flight” state to a parasympathetic “rest-and-digest” state.
