They shift focus from static neural states to neural dynamics. They add computational correlates defined as probabilities encoded by those states.\n\nCore result: FEP supplies a route from computational descriptions to explanations of consciousness. It handles cases of consciousness without ongoing sensory input or behavior. It distinguishes systems that merely simulate conscious processes from systems that instantiate them.\n\n## Exact primary passages\nThe paper states: \"Under the free energy principle, neural correlates should be defined in terms of neural dynamics, not neural states, and should be complemented by research on computational correlates of consciousness – defined in terms of probabilities encoded by neural states.\" (Abstract, 2021).\n\nIt continues: \"We argue that these restrictions brighten the prospects of a computational explanation of consciousness, by addressing two central problems. The first is to account for consciousness in the absence of sensory stimulation and behaviour. The second is to allow for the possibility of systems that implement computations associated with consciousness, without being conscious.\" (Abstract, 2021).\n\nFurther: \"Given the notion of computation entailed by the free energy principle, we derive constraints on the ascription of consciousness in controversial cases (e.g., in the absence of sensory stimulation and behaviour). We show that this also has implications for what it means to be, as opposed to merely simulate a conscious system.\" (Abstract, 2021).\n\n## Convergence patterns touched\nThe work links thermodynamic and information-theoretic minimization (FEP) to structured neural activity and probabilistic inference. It touches flow networks and memory-like internal models. It connects active inference to the emergence of mind-like capacities from basic self-organizing dynamics. These map onto the Ladder steps from energy flow to structure to computational processes supporting awareness.\n\n## Relation to the OIP/GRAIN synthesis\nThe paper supplies a mechanistic bridge at the computational layer. FEP minimization produces internal models that encode probabilities; these models support the transition from raw dynamics to conscious processing. It supports the synthesis claim that reliable energy-flow patterns generate the narrow family of structures that include memory and mind. It does not address the Mirror Layer or the full end-to-end Ladder from difference to life.\n\n## Honest limits and disconfirming edges\nThe account remains framework-level. No new empirical data establish that FEP dynamics are necessary or sufficient for consciousness. Reductionist objections apply: the same equations may describe non-conscious systems equally well. The distinction between simulation and instantiation rests on interpretive ascription rules rather than direct measurement. Claims about islands of awareness or minimal unifying models stay speculative without further constraints from biology or experiment.\n\n## Claims\n- Claim c1: FEP requires NCC definitions in terms of dynamics rather than static states.
