Mapping Brain Function Through Amplitude, Coherence, and Phase Dynamics: A Rhythmic Ontology of Cognition

Abstract In the present intellectual work, we introduce a rhythmic ontology of cognition that reframes mental function not as representational computation but as phase-based participation within nested oscillatory fields. Departing from traditional mechanistic models, we propose that intelligence arises through recursive modulation of amplitude, coherence, and phase—collectively termed A–C–P dynamics. The brain is conceptualized as a synchronizing interface, aligning physiological and relational rhythms across ontogenic domains. Through the present framework, core cognitive processes—perception, attention, memory, emotion, imagination, language, and executive modulation—are mapped as harmonic expressions of Consciousness rather than algorithmic outputs.Our model synthesizes empirical findings in neural oscillations and cross-frequency coupling with philosophical insights into temporality, resonance, and recursive structure. Each function is reconceptualized as an emergent waveform grammar, where mental states reflect dynamic entrainment rather than symbolic manipulation. We further articulate Consciousness as the foundational field through which cognitive phase grammar is modulated, presenting Latentively as the precursive signature of unresolved resonance. Applications include new paradigms for neurodivergence classification, therapeutic attunement, neurophenomenological validation, and rhythm-informed AI simulation. By framing cognition as rhythmic participation, we offer a theoretical and methodological bridge between brain dynamics and consciousness-based modeling—transforming cognition from a modular system into a compositional score of “Being.”
