Biological Coherence and Delayed-Access Regeneration

Delayed-Access Surgical Systems (DASS) address situations in which definitive surgical capability cannot reach an injured patient within the desirable clinical interval. Delayed-Access Regenerative Systems (DARS) extend this architecture from preservation toward biological restoration by proposing systems capable of initiating, sustaining, monitoring and adapting tissue regeneration during prolonged absence of definitive reconstructive access (Refs. 1–2). A technological basis for this progression is the closed-loop regenerative implant described in PCT/AU2025/050989, internationally published as WO2026055724A1, with John McHugh and Jonathan McHugh as inventors (Ref. 3). This paper proposes Biological Coherence as a systems hypothesis addressing a deeper question created by closed-loop regeneration: what biological state must an adaptive regenerative system measure and control? Living tissue is modelled as a distributed dynamical system possessing multidimensional spectral states across electrical, ionic, mechanical, metabolic, vascular and biochemical domains. The paper's single load-bearing claim is that successful regeneration depends not solely upon the magnitude of individual biological processes, but upon their coordinated organisation — coherence — across frequency, phase, space and physiological domain; this claim is distinguished from, and related to, existing bioelectric models of regeneration in which patterning information is carried by endogenous voltage gradients rather than by cross-domain synchrony (Refs. 4–5). Every other construct in the paper is an optional extension of that single claim, explicitly disposable without affecting it. The core theory requires no unidentified physical field and predicts that regenerative state may alter coupling to recognised metabolic and environmental energy sources. A hexagonal lattice is proposed as one candidate geometry capable of modifying biological coupling and coherence. The theory further introduces Organismic Overwatch, a systems-level descriptor of the integrated cognitive, autonomic, endocrine, immune, metabolic and behavioural state of the intact organism. A third extension, the Geomagnetic Coupling Hypothesis, proposes that regenerative state may modulate coupling to the local geomagnetic environment through mechanisms not captured by the core model; unlike a generic appeal to unspecified external energy, this extension is grounded in the radical-pair mechanism, an established, peer-reviewed biophysical account of how geomagnetic-strength fields can influence biochemical reaction outcomes without net energy transfer (Refs. 7–8). The hypothesis is bounded to three named coupling mechanisms plus an explicit confound-control pathway that must be excluded first, and is not required by the core Biological Coherence model.
