This theoretical paper proposes the Sensation Modulating Network (SMN), a model of cognition that treats the entire body as a cognitive agent organized by opponent dynamics at all scales. The core thesis argues that "haltability"—the active maintenance of opponent equilibrium—provides the architectural foundation for object-directed phenomenology, with the body's physical properties (gravity, elasticity, topology) performing constructive cognitive work rather than relying on brain-based representations. The model positions existing theories like sensorimotor enactivism and active inference as special cases within a broader framework, arguing that cognition emerges from whole-body dynamics with the nervous system serving as an integrating core rather than a command center.
Why it matters
This work attempts to resolve longstanding debates between traditional cognitivism and embodied (4E) cognitive science by providing a unified architectural framework. If validated, it could reshape how we understand cognition, perception, and consciousness, with potential implications for robotics, artificial intelligence, and therapeutic interventions that leverage whole-body rather than brain-centric approaches.

Abstract: We propose the Sensation Modulating Network (SMN): the cognitive agent as the whole body, organized at every scale by opponent dynamics, built from Sensation Modulators — tissue that senses and acts through one substrate — paired into Coordinated Action Zones routed by a body-wide broadcast. It is an inclusive model of the body, in which gravity, elasticity, and the body’s topology and geometry do constructive cognitive work. The paper is scoped to what such a body constructs at its foundation — a self-model, a world-model in that self’s frame, and object-directedness — each built by the body’s physics, not assumed as a primitive. The architecture is generative: one small kit of primitives whose morphological variations (chain, sheet, tube, layered, appendicular) construct experience by the same mechanism, an invariance shown for the self-model across body plans and scales. The central thesis: haltability — the active holding of an opponent equilibrium — is the architectural condition object-directed phenomenology requires; a second principle, that an object is a bundle of more than one property, carries it from felt resistance to a genuine object. A companion bench realizes each construction as a runnable, falsifiable experiment with a pre-registered order parameter and matched foil. We place the principal competing accounts — sensorimotor enactivism, active inference, and ecological and affordance-based theories — as limiting cases within a wider landscape, stating in each case the criterion that would tell them apart, and give systems and cognitive neuroscience its place: the nervous system as the integrating core that makes the body one, not a commander over it. On this account, the cognitivism-4E impasse reflects an incomplete architecture of the embodied agent: its resolution begins not with the brain alone but with the whole body.
