The most realistic simulations couple models across scales. A multi-scale framework might embed an ODE model of intracellular signaling (e.g., cAMP pathway) within an agent‑based model of a cell population, which feeds into a PDE compartment for tissue diffusion, all linked to a whole‑body circulation model. Such a framework has been used to simulate the response of the HPA axis to a flight‑or‑fright stimulus, predicting not only the rapid neural release of CRH but also the slower glucocorticoid feedback at multiple levels.
