Abstract This work introduces the Mahmoud Field–Core Model, a conceptual theoretical framework proposing that physiological stability may emerge from the interaction between structural biological processes (Core) and their associated electromagnetic dynamics (Field). The model describes living systems as coupled dynamical systems operating across multiple spatial and temporal scales. A mathematical formulation is proposed to represent internal coupling, spatial regulation, and external perturbations. While the framework remains non-predictive at this stage, it provides a structured basis for exploring multi-scale coordination in biological systems. By integrating perspectives from systems biology, biophysics, and complex systems theory, this work aims to contribute to the understanding of physiological coherence and adaptability. Description This publication presents Version 2 of the Mahmoud Field–Core Model, a conceptual framework describing the interaction between structural biological processes and their associated electromagnetic dynamics. This updated version includes improved mathematical consistency, refined theoretical positioning, and enhanced structural clarity following critical review. The work is intended as a theoretical contribution and a basis for future interdisciplinary research in systems biology and biophysics. This is Version 2 of a previously published concept (DOI: 10.5281/zenodo.18857103), significantly improved and structurally refined.
