Autonomic Nervous System & Sociality
- Our autonomic nervous system links mind and body and modulates our responses to stress and safety.
- Polyvagal theory explains that sociality signals safety, which downregulates threat reactions and supports health and restoration.
Two Distinct Vagal Pathways
- Polyvagal theory identifies two vagal pathways: ventral vagus linked to social engagement and dorsal vagus associated with more primitive responses.
- The ventral vagal pathway enables mammals to broadcast safety with facial expressions and vocalizations.
Face and Voice Reflect Physiology
- Our face and voice reflect our autonomic state, signaling safety or threat to others.
- Loss of ventral vagus activity flattens facial expressivity and intonation, indicating vulnerability and defensive physiology.
