I am a big fan of Rothschild. Her earlier book (2000) elevated awareness of the autonomic nervous system (ANS), the substrate of all health, in the psychotherapy world, and taught us to look for and precisely recognize ANS signals in order to appropriately support recovery from trauma. Her new book adds excellent additional detail, including a “six-categories-of-ANS” poster that can now be viewed on the wall of our classroom at CSES. The bulk of the book is about therapy insights, which I found to be excellent; my concerns were just in a few pages of her Chapter Two.
The problem for me starts with Rothschild’s description of Polyvagal Theory (PVT), which occupies two pages in the chapter. She summarizes PVT as being the discovery of the “ventral vagus” function as distinct from the previously-known “dorsal vagus” function, which is the foundation of the parasympathetic branch of the autonomic nervous system. Both down-regulate the heart, but in different ways. She states that calm states arise from the ventral branch, and that collapse states arise from the dorsal branch. This is not all wrong, but for a person of Rothschild’s immense professional stature, I was really hoping for more.
