An experiencial field of autonomic states

The North Star illustrates how experience is shaped through the fundamental patterns of the nervous system. The model builds on polyvagal theory and integrates key principles from Somatic Experiencing into a unified framework for understanding stress, freeze, presence, and vitality.

Three primary directions

From a polyvagal perspective, the nervous system operates along three primary pathways: sympathetic mobilization, dorsal immobilization, and ventral social regulation. These are evolutionarily developed survival strategies. Mobilization supports fight and flight. Immobilization supports protection and energy conservation. Ventral regulation supports contact, connection, and coordination across both activation and rest.

Four domains of state

The North Star shows how these systems shape experience across four core states. When sympathetic activation occurs without ventral grounding, stress, tension, and reduced contact emerge. When dorsal dominance takes over, energy may drop, contact fades, and freeze or dissociative tendencies may arise. Both states are adaptive in the presence of real threat, but become limiting when they persist and lose flexibility.

Flexible and rigid organization

At the same time, the model highlights that mobilization and immobilization can be integrated when ventral regulation is available. Activity can unfold within contact. Rest can unfold within safety. The key distinction is not between activation and rest, but between flexibility and rigidity — between remaining connected and losing connection.

Integration of perspectives

Here, polyvagal theory and Somatic Experiencing converge. Polyvagal theory describes the structural organization of the nervous system. Somatic Experiencing describes how mobility can be restored when the system becomes fixed in one sided patterns. Through processes such as pendulation, titration, and the completion of previously inhibited responses, the system can gradually move from stress or freeze toward integrated contact, with greater orienting capacity.

A navigational map

The North Star functions as a navigation map. It shows where experience is situated and what kind of movement may be needed. Health can be understood as movement flexibility — the ability to move between activation and protection without losing grounding.

An evolutionary perspective

From an evolutionary perspective, this flexibility reflects adaptive capacity. Survival has always depended on rapid mobilization, effective protection, and social coordination. Modern conditions activate the same systems, often in prolonged patterns without natural resolution. When mobilization remains incomplete or immobilization becomes prolonged, flexibility is reduced.

A core principle

The North Star points to a central principle. Stress and freeze are adaptive responses. The challenge arises when organization becomes rigid and movement stops.

Conditions for restoring mobility

For mobility to return, sufficient safety in the environment is required. In contact with nature, relationships, and light, the system can regain orientation and mobility without losing grounding.

A framework for integration

The model offers a framework for restoring flexible autonomous movement through the gradual integration of mobilization, contact, and rest. It serves as a compass for navigating human experience, linking neurophysiological structure with a process of development.
