tVNS (Transcutaneous Vagus Nerve Stimulation)

Jul 1, 2026

tVNS — Transcutaneous Vagus Nerve Stimulation

Micro-current delivered to the skin around the ear (auricular region) stimulates the vagus nerve and activates the parasympathetic nervous system.

How It Works

  1. Small electrodes attached to the auricular region of the ear
  2. Gentle electrical stimulation travels via the auricular branch of the vagus nerve to the brainstem
  3. Activates parasympathetic nervous system; modulates norepinephrine and acetylcholine
  4. Promotes relaxation and recovery; enhances neuroplasticity

Applications

  • Hyperarousal and chronic stress
  • Attention and focus enhancement
  • Pre-session preparation for neurofeedback
  • Cases requiring parasympathetic activation
