This is an exciting time in the fields of mental health and neuroscience. We are beginning to better understand how the brain and the body work with greater refinement as technology evolves. Through Stephen Porges’ work with the vagus nerve, we have a greater understanding of how our bodies respond to our world automatically, outside of conscious awareness - that is, from our autonomic nervous system which involves the sympathetic and parasympathetic nervous systems.
The Vagus Nerve - A Brief Overview
The vagus nerve is the tenth cranial nerve and is responsible for a number functions in the body. In terms of how we interact with our world, the vagus nerve controls the parasympathetic nervous system, sometimes referred to as “the relaxation response”. We now know that there are actually two parts to the parasympathetic nervous system. One helps us engage socially in a relaxed manner and the other shuts down our system to protect us in the event of perceived life threatening danger.
