Analyses of EEG Oscillatory Activities During Slow and Fast Repetitive Movements Using Holo-Hilbert Spectral Analysis

Neural oscillatory activities existing in multiple frequency bands usually represent different levels of neurophysiological meanings, from micro-scale to macro-scale organizations. In this paper, we adopted Holo-Hilbert spectral analysis (HHSA) to study the amplitude-modulated (AM) and frequency-modulated (FM) components in sensorimotor Mu rhythm induced by slow- and fast-rate repetitive movements. The HHSA-based approach is a two-layer...
