When The Polyvagal Theory was published in 2011, it took the therapeutic world by storm, bringing Stephen Porges's insights about the autonomic nervous system to a clinical audience interested in understanding trauma, anxiety, depression and other mental health issues. The book made accessible to clinicians and other professionals a polyvagal perspective that provided new concepts and insights for understanding human behavior. That book was brilliant but also quite challenging to read for some.
The Pocket Guide to the Polyvagal Theory is an introductory chapter which discusses the science and the scientific culture in which polyvagal theory was originally developed. Publication of this work enables Stephen Porges to expand the meaning and clinical relevance of this groundbreaking theory.
