IntroductionHuman neural oscillations are organized according to golden ratio (φ = 1.618) mathematics: frequencies follow f(n)=f0×φn where f0≈7.6 Hz. This architecture manifests as spectral peak depletion at integer n positions (band boundaries) and enrichment at half-integer positions (band centers), providing empirical validation of a previously theorized φn architecture and identifying the absolute fundamental frequency f0 = 7.6 Hz. This organization was discovered and validated through two c
