Transcutaneous Vagus Nerve Stimulation (tvns) Devices
overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
Transcutaneous Vagus Nerve Stimulation (tVNS) devices are non-invasive medical or neuromodulation tools designed to stimulate the vagus nerve through the skin. By delivering electrical impulses via electrodes placed on areas such as the ear or neck, these devices aim to modulate neural activity associated with various physiological and psychological functions. They are used for therapeutic purposes, including treatment of depression, anxiety, epilepsy, and recent research explores their potential in managing inflammatory and metabolic conditions.
