What is the Vagus Nerve?

The vagus nerve is, in fact, a pair of nerves that serve as a two-way communication channel between the brain and the heart, lungs and abdominal organs, plus structures such as the oesophagus and voice box, helping to control involuntary processes, including breathing, heart rate, digestion and immune responses.

This is a very extensive article that explains vagal nerve triggering and stimulation as well as a host of possibilities for treatments, including possible solutions for mental health.

“The word vagus derives from the Latin for “wandering” – a nod to the complex and meandering path it takes through the body, and the diversity of physiological processes under its influence. Rather than popping a pill to alleviate illness, perhaps someday it will be possible to breathe, hum or zap our way to better health.”

Exciting!
