The nanoscale reconstruction of a cubic millimeter of human temporal cortex (H01dataset) revealed "axon whorls"—rare structures in which axons coil into elaborateknot-like formations—whose function remains entirely unknown. We propose that axonwhorls are frequency-selective resonant elements within a multi-layered neuralsynchronization system. The coiled geometry of the whorl confers inductance-likeelectrical properties, creating a passive filter that preferentially transmits oscillatorysignals near its resonant frequency, plausibly in the gamma band (30–100 Hz). Withina Kuramoto coupled-oscillator framework, this frequency-dependent filtering transformsstandard sinusoidal coupling into a higher-harmonic coupling function, promotingfrequency-selective synchronization, cluster formation, and multistability. We furtherpropose that the noradrenergic system gates whorl activation through its inverted-Umodulation of neural signal-to-noise ratio: during states of optimal arousal, noisereduction shifts the local oscillatory power spectrum past the resonance threshold,transiently activating whorl-mediated coupling enhancement. As an optional extensionconsistent with biological redundancy, we suggest that the whorl’s electromagneticgeometry may provide localized shielding that supports transient quantum coherencein intraneuronal microtubules—an additional but non-essential performance channel.The hypothesis also offers a structural account of epileptic hypersynchronization:dysregulated whorls may act as constitutively active synchronization boosters. Theframework is modular—each component can be independently tested andfalsified—and we identify five specific predictions addressable through computationalmodeling, connectomic analysis, and electrophysiology. This represents the firstfunctional hypothesis for axon whorls reported in the literature.
