High-Frequency Neuromotor Organization: Inferior-Olivary Timing, Olivo-Cerebellar Coordination, and Axonal Signal Integrity

This working paper proposes a hypothesis-driven theoretical framework for investigating High-Frequency Neuromotor Drive (HFND) in the 400–1000 Hz range. Rather than positing high-frequency firing in individual neurons, the framework models how macroeconomic temporal structures can emerge through population-level interleaved phase coding and olivo-cerebellar network coordination. The paper connects three distinct levels of sensorimotor inquiry: Central Node: Phase synchronization within the inferior olive modeled via the Kuramoto order parameter. Conduction Node: The role of axon-myelin geometry (g-ratio) and membrane biophysics in maintaining high-frequency temporal fidelity. Peripheral Node: Potential frequency-dependent electromechanical coupling within the collagen matrix of tendons. Finally, a rigorous experimental validation protocol is outlined—utilizing high-bandwidth HD-EMG, high-density EEG, and synchronized oculomotor/postural tracking—to separate genuine physiological signals from artifacts and test the proposed limits of sensorimotor latency. This framework aims to bridge first-person phenomenological observations of rapid motor recovery and stabilization with reproducible, quantitative neuroscience.
