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.

REVAI is developing a technology that will allow for non-invasive stimulation of the vagus nerve via an earbud placed in contact with the outer ear. This device couples highly precise nerve activation and audio inputs to produce the desired neuromodulatory effect. The consumer-ready hardware will interface with intuitive software that allows for custom programming of audio and stimulus parameters as needed for each unique application.
