Transcutaneous Vagus Nerve Stimulation (tVNS)
Stimulating the body's own calming pathway to treat the brain.
What Is tVNS?
The vagus nerve is the longest cranial nerve in the body, connecting the brain to the heart, lungs, gut, and immune system. It plays a central role in regulating mood, inflammation, and the stress response.
Transcutaneous vagus nerve stimulation (tVNS) delivers gentle electrical stimulation to a branch of the vagus nerve accessible through the ear. It is non-invasive, painless, and does not require surgery or implantation.
What Does tVNS Treat?
- Depression — modulates brain circuits involved in mood regulation
- Anxiety — activates the parasympathetic nervous system to reduce the stress response
- Inflammation — the vagus nerve is a key regulator of the body's inflammatory response
- Chronic pain — modulates pain processing pathways
- Autoimmune conditions — emerging evidence for conditions driven by inflammatory processes
- PTSD — helps regulate autonomic nervous system dysregulation
How It Works
A small device delivers mild electrical stimulation to the auricular branch of the vagus nerve in the ear. This signal travels to the brainstem and activates pathways that influence mood, arousal, inflammation, and autonomic function.
Why tVNS at BrainHope
We integrate tVNS into a broader treatment approach that includes brain measurement (EEG, HRV) and other stimulation modalities. Rather than using tVNS in isolation, we use it as part of a personalized, multi-modal strategy.
Heart rate variability (HRV) monitoring allows us to track vagal tone and assess treatment response objectively.
What to Expect
- A small clip-like device is placed on the ear
- Stimulation feels like a mild tingling or pulsing
- Sessions last 15 to 30 minutes
- No side effects for most patients
- Can be used at home between office visits
