The Model
The Coherence Model: A Systems Framework for Human Regulation
Coherence is the capacity of biological systems to maintain stability while adapting to change. It is not a static state, but a dynamic balance across systems.
The Coherence Model is a proposed systems framework that integrates concepts from established areas of physiology, neuroscience, stress biology, metabolism, and systems thinking into a unified model of human regulation.
The Five Layers
The Coherence Model proposes a five-layer framework for understanding how regulatory influences may interact across biological systems.
Meaning and Context
The model proposes that perceived safety, predictability, identity, and expectation shape the conditions under which downstream regulation unfolds—that context is interpreted before physiological change occurs.
Nervous System State
The autonomic nervous system translates contextual interpretation into physiological state. Patterns of activation, vigilance, or restoration determine how energy is allocated across the body.
Metabolic and Endocrine Coordination
Hormonal signaling, metabolic regulation, circadian timing, and mitochondrial function determine how energy is produced and distributed in response to regulatory demands.
Structural and Tissue Organization
Musculoskeletal structure, connective tissue, organ organization, and movement patterns adapt over time to the regulatory priorities established above.
Cellular and Biochemical Processes
Cellular signaling, inflammatory pathways, and biochemical reactions operate within the constraints created by the regulatory layers above them.
The Three Principles
Core Dynamics Governing Health and Dysfunction
Health emerges when communication across these layers remains coherent—aligned in timing, proportion, and purpose. When coordination degrades, regulatory drift begins. The model proposes three core dynamics that govern this process.
Regulatory Hierarchy
The model proposes that higher-order contextual and nervous system processes shape the conditions under which lower-level biological functions operate—that influence tends to flow from higher-order organization toward lower-order processes, while constraints flow upward from structural and biochemical limitations.
Regulatory Drift
Loss of coordination across layers leads to gradual compensation and increasing energetic cost. The model proposes that this drift may begin at higher levels of organization before biochemical or structural changes become measurable—which would help explain why many individuals experience declining resilience before any pathology appears.
Coherence Restoration
The model proposes that durable recovery is more likely when regulatory alignment is restored across layers rather than when isolated outputs are forced at a single level—allowing biological systems to reorganize more efficiently over time.
Why a Layered Model Matters
May help explain declining resilience before diagnosis
Many individuals experience fatigue, slow recovery, and lingering stress responses while diagnostic testing reveals little abnormality. The model proposes that this pattern may reflect drift beginning at higher levels of organization—before biochemical or structural changes become measurable.
Offers a framework for why some interventions don't hold
When support targets a lower layer—such as chemistry or structure—without addressing the regulatory conditions established at higher layers, the system may compensate and return to its prior state. The model proposes that more durable change may require restoring alignment across layers, not forcing isolated outputs.
The Drift Cascade
The model proposes that when systems fall out of alignment, a progressive cascade may follow. Most interventions occur at the symptom level. This model addresses the earlier stages.
Scientific Foundations
The Coherence Model draws from established research across multiple disciplines. It does not claim to have been validated as a unified framework—it proposes a synthesis of existing knowledge that warrants further evaluation.
