Preprint_ The Onion Model of Functional Regulation (OMFR)_ A Multilayer Diagnostic Framework for Emergent Self-Regulation and Complex Psychosomatic Phenomena

Arising from clinical challenges in general medical practice and the need for a structured understanding of complex functional disorders, this paper presents the Onion Model of Functional Regulation (OMFR)—the diagnostic implementation layer of the Hadlich Field Resonance Theory (HFRT), a unified framework for emergent coherence across somatic, cognitive, and psychosocial domains. OMFR models the human organism as a stratified system of seven functional layers, each representing a distinct domain of self-regulation. Dysfunction is reconceptualized not as isolated pathology, but as a resonance collapse within and across these layers—triggered by sustained incoherence between internal processing logics and environmental demands. Three diagnostic axes structure the model: – cognitive architecture (System 1, 2, or R), – regulatory strategy (stabilization, compensation, collapse), – and social-expressive coherence. By mapping complex syndromes such as ME/CFS, burnout, or chronic pain through a field-coherent lens, OMFR enables architecture-sensitive diagnosis and coherence-restoring interventions—shifting the clinical focus from symptom control to systemic reintegration.
