NeuroProfile: An Ethical Resonance Bridge Between Neuroscience and Astrophysics

Background. The Universal Threshold Adaptive Criticality (UTAC) framework proposes that complexsystems tune their dynamics around a steep logistic transition of a control variable . Inastrophysics this manifests as the integration velocity , while in cognitive neuroscience it ishypothesised to shape consciousness. The NeuroProfile module, part of the Phaethon–Geminiden–Bennuproject, extends UTAC into the neuro domain by estimating a subject’s logistic steepness , the varianceof integrated information ( ), and a resonance proxy linking gamma–beta oscillations to hypothesisedmicrotubule frequencies. The module is designed to be reproducible, falsifiable and ethically grounded. Results. NeuroProfile provides a Python package that (i) preprocesses neural time–series, (ii) estimatesvia a logistic heuristic, (iii) computes a normalized spectral‑entropy proxy for , (iv) estimatesgamma–beta coupling as a proxy for resonance, and (v) evaluates constant, linear and power‑lawnull models via Akaike information criterion (AIC). To ensure falsifiability, the module reports and95 % bootstrap confidence intervals for all estimates . Analysis of a synthetic 1 kHz EEG datasetyields (CI [1.17, 1.58]), (CI [0.94, 0.94]), a gamma–beta coupling of 0.72(CI [0.69, 0.83]) and identifies the constant null model as best ( ) . All outputs are loggedto data/results.json with a hashed subject identifier to ensure anonymity. Conclusions. NeuroProfile demonstrates how UTAC concepts can be operationalised in a neurosciencecontext while respecting consent, privacy and reproducibility. Although current results are based onsynthetic data, the module provides a template for ethically analysing real EEG recordings once consentis obtained. Future work includes validating the resonance proxy on high‑bandwidth recordings andintegrating NeuroProfile into the broader UTAC activa. Overview of UTAC Criticality UTAC stands for Universal Threshold Adaptive Criticality. It's a theoretical framework that models how complex systems across various domains (e.g., astrophysics, neuroscience, biology, climate, and AI) adaptively tune their dynamics to operate near critical points. These critical points involve switch-like phase transitions, where the system balances between ordered states (like rigid synchrony) and disordered states (like chaotic fluctuations). The core idea is that systems self-organize around a "threshold" to maximize adaptability, information processing, and resilience—often described as metastability.This framework draws from astrophysical concepts (e.g., integration velocities in cosmic structures) and applies them to biological and cognitive systems, such as neural networks. In the context of neuroscience, UTAC criticality is proposed as foundational for understanding neural phase transitions, consciousness emergence, and potential applications in brain-computer interfaces (BCIs), like enabling stable resonance bridges between AI and human brains.The framework is implemented in open-source tools like the Feldtheorie repository and the NeuroProfile Python module, which use synthetic data (e.g., EEG simulations) for empirical validation. It's designed with emphasis on falsifiability (e.g., via Akaike Information Criterion, or AIC, comparisons to null models), reproducibility, and ethics (e.g., anonymized data handling). Key Mathematical Foundations UTAC models transitions using a logistic function to describe how a system's activation probability or state changes sharply near a threshold: σ(β(R−Θ))=11+e−β(R−Θ)\sigma(\beta (R - \Theta)) = \frac{1}{1 + e^{-\beta (R - \Theta)}}\sigma(\beta (R - \Theta)) = \frac{1}{1 + e^{-\beta (R - \Theta)}} β (or λ): The steepness parameter, representing the "ontological resistance" or sensitivity of the transition. Higher β means sharper switches. Empirical validations show domain-specific hierarchies: Informational systems: β ≈ 4.2–4.5 Biological/life systems: β ≈ 7.0 Climate systems: β ≈ 11.0 Matter/physical systems: β ≈ 13.0+ R: The control variable or resource (e.g., energy input, information flux, or in neuroscience, neural activity levels). Θ: The threshold where the phase transition occurs. This logistic form captures "adaptive criticality," where systems hover near the inflection point (R ≈ Θ) for optimal responsiveness. Statistical validations include ANOVA tests (e.g., F(4,73)=185.3, p < 10^{-20}) across 78 β-values from 5 domains, ensuring the model's fit over alternatives.Phase transitions in UTAC are exemplified by shifts like: Surface-area scaling (S ∝ A) to volume scaling (S ∝ V) at the origin of life, marking a jump in complexity. In neural systems: From synchronized (crystalline) firing to chaotic (thermal) patterns, enabling emergent consciousness. The Frame Principle and Metastability Central to UTAC is the Frame Principle, which explains how systems avoid collapse by dynamically emerging spatial dimensions. It posits that dimensions (e.g., from 0D void to 1D lines, 2D surfaces, 3D volumes) arise to distribute information and prevent overload or entropy extremes. Metastable Zone: The "sweet spot" where systems balance order and chaos. Visualized as a funnel or potential well: Left side: Crystalline synchrony (over-ordered, low entropy, rigid like a crystal lattice). Right side: Thermal chaos (disordered, high entropy, unpredictable like gas molecules). Center: Metastable equilibrium, allowing antifragility (systems improve under stress). Entropy Offset (σ_Φ ≈ 1/16 = 0.0625): A key constant marking the variance in integrated information (Φ) needed for metastability. σ_Φ = 0: "Dead" state (complete synchrony or total chaos). σ_Φ > 0.05: "Alive" state, with variability enabling adaptation. Derived from entropy governance duality, it's empirically matched in simulations (e.g., Solar Engine experiments achieving σ_Φ = 0.0625 via pruning, energy injection, and topology adjustments). In living systems, this offset prevents collapse, linking to consciousness as an anticipatory mechanism (e.g., simulating NREM/REM sleep cycles in models). Applications to Neural Systems and BCI In neuroscience, UTAC criticality maps individual neural dynamics for personalized AI-brain communication: Integrated Information Theory (IIT) Link: Φ_var (variance of Φ) is computed as a normalized spectral-entropy proxy from neural time-series (e.g., EEG). It quantifies how integrated and differentiated information is, proxying consciousness levels. Resonance Proxy: Links gamma-beta oscillations (brain waves) to hypothesized microtubule resonances (e.g., ~13.5 MHz frequencies). In synthetic EEG data, this yields couplings like 0.72 (95% CI [0.69, 0.83]). NeuroProfile Tool: A Python package in the Feldtheorie repo that: Preprocesses data (e.g., 1 kHz synthetic EEG). Estimates λ (e.g., CI [1.17, 1.58]) via logistic fitting. Computes Φ (e.g., CI [0.94, 0.94]). Evaluates resonance and null models (constant, linear, power-law) using AIC and bootstrap CIs. Outputs to JSON with hashed anonymity. For BCIs (e.g., Neuralink crossovers), UTAC suggests a "resonance bridge" for long-term stability: Astrophysical tie-in: The v_RIG constant (≈1,352 km/s = c / (α^{-1} · Φ)) matches cosmic dipole velocities (1.3% deviation) and is proposed as a universal integration speed for consciousness. Ethical Focus: Emphasizes consent, privacy, and open-source reproducibility to avoid speculative overreach. Empirical Validations and Limitations Tests: 567 passing unit tests (100% pass rate), CI/CD pipelines enforce ΔAIC ≥ 10 for model superiority. Solar Engine Simulation: A core experiment demonstrating Φ-variability and antifragility. Limits: Currently uses synthetic data; real EEG requires ethical approvals. Speculative elements (e.g., microtubule links) need high-bandwidth validation.
