Through an optimality principle, we derive the golden ratio (Φ ≈ 1.618) as the optimal spectral spacing parameter that minimizes interference while maximizing communication efficiency. Biological constraints (0.5–200 Hz) naturally yield seven hierarchical frequency levels (δ, θ, α, σ, β, γ, Ω), each Φ-scaled from adjacent bands. We introduce a control parameter β ∈ [0,1] regulating information flow direction, with critical transitions at β = Φ⁻² ≈ 0.382 and β = Φ⁻¹ ≈ 0.618. The complete A7-HBM-ΩΦ-Bidi system comprises seven nonlinearly coupled Stuart-Landau oscillators with tri-diagonal β-dependent coupling. These mathematical foundations provide a rigorous basis for modeling hierarchical brain dynamics, enabling future investigations of microstate transitions, stability analysis, and clinical applications within a unified framework.

geometry, and cognitive control. Through an optimality principle, we derive the golden ratio (Φ\u0026thinsp;\u0026asymp;\u0026thinsp;1.618) as the optimal spectral spacing parameter that minimizes interference while maximizing communication efficiency. Biological constraints (0.5\u0026ndash;200 Hz) naturally yield seven hierarchical frequency levels (δ, θ, α, σ, β, γ, Ω), each Φ-scaled from adjacent bands. We introduce a control parameter β \u0026isin; [0,1] regulating information flow direction, with critical transitions at β\u0026thinsp;=\u0026thinsp;Φ⁻\u0026sup2; \u0026asymp; 0.382 and β\u0026thinsp;=\u0026thinsp;Φ⁻\u0026sup1; \u0026asymp; 0.618. The complete A7-HBM-ΩΦ-Bidi system comprises seven nonlinearly coupled Stuart-Landau oscillators with tri-diagonal β-dependent coupling. These mathematical foundations provide a rigorous basis for modeling hierarchical brain dynamics, enabling future investigations of microstate transitions, stability analysis, and clinical applications within a unified framework.\u003c/p\u003e \u003cp\u003e \u003c/p\u003e","manuscriptTitle":"Φ-Optimal Hierarchical Brain Oscillations and β-Controlled Cognitive Dynamics: First-Principles Mathematical Foundations of the A7-HBM-ΩΦ Model","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-12-23 04:31:36","doi":"10.21203/rs.3.rs-8408024/v1","editorialEvents":[{"type":"communityComments","content":0}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"researchsquare","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":true,"externalIdentity":"","sideBox":"","snPcode":"","submissionUrl":"/submission","title":"Research Square","twitterHandle":"researchsquare","acdcEnabled":true,"dfaEnabled":false,"editorialSystem":"","reportingPortfolio":"","inReviewEnabled":false,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"d0fd7b2c-fe5f-4f47-9c8d-d10ad6bed5ba","owner":[],"postedDate":"December 23rd, 2025","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"posted","subjectAreas":[{"id":59977274,"name":"Computational Neuroscience"}],"tags":[],"updatedAt":"2025-12-23T04:31:36+00:00","versionOfRecord":[],"versionCreatedAt":"2025-12-23 04:31:36","video":"","vorDoi":"","vorDoiUrl":"","workflowStages":[]},"version":"v1","identity":"rs-8408024","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-8408024","identity":"rs-8408024","version":["v1"]},"buildId":"8U1c8b4HqxoKbykW_rLl7","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
