The Polyvagal Theory posits that co-regulation through social behavior is a biological imperative—a need as hardwired into us as that for food or sleep.

the auto-nomic nervous system consists of three neural circuits: the ventral branch of the vagus nerve (positive states of relaxation and social engagement), the spinal sympathetic chain (fight or flight), and the dorsal branch of the vagus nerve (slowdown, shutdown, and depressive behavior).

Over the course of evolution, the three pathways of the autonomic nervous system (dorsal, sympathetic, and ventral) emerged and formed the building blocks of the system (hierarchy). Our preferred place, the place where we find experiences of health, growth, and restoration, is anchored in the ventral vagal state of safety and connection. When we
