The vagus nerve is the longest nerve in the human body and serves as a communication pathway between the brain and several major organs. Vagus nerve stimulation (VNS) via an implanted electrode has been approved by the FDA for the treatment of epilepsy and depression. Recent VNS research and clinical trials have shown its potential benefits for managing tinnitus, Post Traumatic Stress Disorder (PTSD), and anxiety, as well as accelerating verbal learning and language acquisition.
