Cross-Level Coupling as a Necessary Condition for Consciousness: An Empirical Challenge to Neural Sufficiency Models

This paper proposes a testable challenge to the assumption that neural integration alone is sufficient for consciousness. This paper challenges the sufficiency claim. The Integrative Field Model (IFM) proposes that consciousness depends on the integrity of cross-level coupling, particularly between neural and interoceptive systems. It advances a testable prediction: selective disruption of interoceptive–neural coupling, under conditions of preserved neural integration, will degrade conscious coherence in ways not captured by existing neural metrics. This prediction generates a direct empirical distinction between single-level integration theories and multi-level field models. Experimental and clinical paradigms capable of testing this claim are outlined. The results would determine whether neural integration alone is sufficient for consciousness or whether multi-level coupling is constitutive.
