Polyvagal Theory, developed by Stephen Porges, provides a neuroscience framework that explains many aspects of left brain - right brain in terms of the nervous system's safety-detection mechanisms.
The Three States of Polyvagal Theory and Left Brain - Right Brain
Ventral vagal (safe and social): Optimal state for connection, learning, and left brain - right brain management
Sympathetic mobilization (fight or flight): Anxiety-type left brain - right brain responses
Dorsal vagal shutdown (freeze/collapse): Depression and dissociation-type left brain - right brain
Neuroception and Left Brain - Right Brain
Neuroception — the body's unconscious safety-detection — can be dysregulated in left brain - right brain, causing false alarms (sensing danger when safe) that drive left brain - right brain responses.
Polyvagal-Informed Left Brain - Right Brain Treatment
Therapy that acknowledges the body's state — helping clients move into ventral vagal 'safe and social' — transforms left brain - right brain management.
Safe relationships, co-regulation, and body-based practices are particularly emphasized.
