Polyvagal Theory explained simply — and what it means for you
By Kenneth Collins · 9 min read
Polyvagal Theory is one of the most significant discoveries in nervous system research in the last 30 years. It explains why you react the way you do under stress — and what you can do about it.
What is Polyvagal Theory?
Polyvagal Theory was developed by neuroscientist Stephen Porges in 1994. His research has revolutionized our understanding of how the autonomic nervous system responds to danger and safety.
The theory is today the foundation for treatment of PTSD, anxiety, chronic pain and many other conditions — including the Body Correction method.
The vagus nerve — the body's superhighway
The core of Polyvagal Theory is the vagus nerve — the longest nerve in the body. It runs from the brainstem down to the heart, lungs, stomach and intestines. It is the primary communication pathway between the brain and the internal organs.
Porges discovered that the vagus nerve actually consists of two branches with very different functions: the ventral vagus (active in safety, creates calm and social connection) and the dorsal vagus (active in extreme danger, creates shutdown and immobilization).
Neuroception: The body constantly scans for danger
Porges introduced the concept of neuroception — the body's ability to scan the environment for danger or safety, without us being conscious of it.
The problem arises when neuroception fails — when the body registers danger even though there is none. That's exactly what happens with chronic stress, anxiety and PTSD. Body Correction works directly with this system — correcting the proprioceptive signals that trigger false alarms.
