Cortical Informational Field Theory VI: The CIFT-EXEC Protocol — A Field-Theoretic Protocol for Optimizing Functional C2[Φ] in Near-Critical Cortical Regimes: Environmental, Behavioral, and Pharmacological Intervention from First Principles

The Cortical Informational Field Theory (CIFT; Papers I–V) establishes that ADHD represents a near-critical cortical field regime in which λ_CIFT fluctuates near the critical threshold λ_c, producing characteristically small and unstable coherence length ξ, elevated non-functional C2[Φ], and fragmented efferent signal structure. The present paper derives, from the field equation ∂_tΦ = D_eff∇²Φ + λ_CIFTΦ − βΦ³ + η(x,t), a structured three-layer protocol — CIFT-EXEC — for optimizing functional C2[Φ] in near-critical cortical regimes during executive function tasks. The protocol addresses the four modulable parameters of the field equation: λ_CIFT (pharmacological layer), η(x,t) (environmental layer), G(x,t) (behavioral layer), and D_eff (long-term physical conditioning). Each intervention is formally derived from its effect on the corresponding term of the equation. Eight falsifiable predictions are derived (six for CIFT-EXEC and two for the inverse CIFT-SLEEP protocol). The protocol is presented as the first field-theoretically grounded intervention framework for executive function optimization in ADHD.
