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.
Por qué ocurre — el mecanismo
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.
Cómo responde el Sistema Avikzar
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.

Preguntas frecuentes
Can the vagus nerve be trained?
Yes — via sport, breathing, singing, cold exposure. Heart rate variability (HRV) measures this training.
