What is the vagus nerve?

The vagus is the key component of the parasympathetic branch of the autonomic nervous system, and because the sympathetic and parasympathetic nervous systems act reciprocally -- when one goes up, the other goes down -- the vagus nerve is critical in many therapeutic areas due to its beneficial effect in restoring balance in cases where sympathetic activity is abnormally raised or parasympathetic activity is lowered.   

“It’s not a drug that I’m putting in my system and its not something that I’m smoking.  So, if you’re telling me that you can put something in my ear and make me better, sign me up every day of the week!”  


- Andy, from Evren's PTSD Pilot Study
