The Brain as a Field-Limiting Transducer: A Constraint-Rendering Model of Consciousness

Abstract

The correlation between neural activity and conscious experience is well established, but the correlational record does not settle whether the brain produces consciousness or constrains it. This paper develops and formalizes a constraint-rendering alternative to production models. On this account the brain functions as a field-limiting transducer: it does not generate the substrate of awareness but imposes boundary conditions on a latent Consciousness Unit substrate, written |Ψ⟩, structuring it into the coherent, bounded, temporally sequenced experiential state |Φ⟩. The model is expressed compactly as |Φ⟩ = Σ_s A_s P_s B̂ |Ψ⟩, and the transducer operator B̂ is resolved into four testable functional roles: boundary formation, resonance stabilization, dimensional compression, and temporal sequencing. Because a model positing an unmeasured substrate risks absorbing any outcome, the account is committed in advance to four discriminating predictions, each stated with the result that would count against it: an ordered dissociation hierarchy among the functional roles, substrate invariance under extreme content loss, mode-specificity across pharmacological perturbations, and a reverse-ordered recovery on offset. The primary anchor case is 5-MeO-DMT, whose whiteout profile appears to dissolve world, body, space, time, and self while subjective experience may persist, and whose recently reported EEG signature — amplified but fractionated slow-wave activity, preserved alpha power, and a steepened rather than flattened energy landscape — is read against these predictions. The amnesia interpretation of that profile, that the whiteout is an ordinary blackout misremembered, is confronted directly as the principal competing account, and a comparative perturbation matrix (dissociatives, general anesthetics, antipsychotics, SSRIs, and an amnestic control) distributes the model's exposure across mechanisms. The argument is comparative and defeasible rather than demonstrative: the model earns consideration by making commitments a production account is not obliged to make and submitting them to the same evidence.
