Vagus nerve and sideration: understanding the link

The vagus nerve orchestrates sideration. Its dorsal branch (evolutionarily oldest) triggers survival immobility. Its ventral branch (newer) handles calm and social connection. Training strengthens the ventral branch.

Warum es passiert — der Mechanismus

Polyvagal Theory (Porges 1994): 3 levels of autonomic nervous system — ventral vagal (social calm), sympathetic (fight/flight), dorsal vagal (sideration). Under extreme threat the order is: ventral → sympathetic → dorsal. Training goal: climb back up instead of down.

Wie das Avikzar-System darauf antwortet

Yehouda teaches 'vagal reset': coherent breathing (5 breaths/min) at session start, jaw stretches, vocal sounds. All tones the ventral vagal and shortens recovery time after stress.
