I observed it in action daily in my work in a youth homeless shelter. Most of the youth I worked with had PTSD and were quick to fight or fly, stress hormones flooding their systems and the limbic system activating their will to survive.

The limbic system functions with our autonomic nervous system to create emotions in response to stimulus. Dr. Stephen Porges theorizes that the autonomic nervous system is involved in our responses to threat and safety in complex ways, and his interest is in the vagus nerve. Porges posits that the ventral vagal parasympathetic nervous system, the sympathetic nervous system, and the dorsal vagal parasympathetic nervous system all have their roles to play. As therapist/educator Justin Sunseri discusses, in the parasympathetic or ventral vagal state, we are “safe and social” and able to “rest and digest.” When functioning well, the ventral vagus nerve helps us produce the tones, facial expressions and listening skills needed for socializing.
