Magnitude squared coherence between two motor unit spike trains recorded from the FDI muscle. Magnitude coherence between two motor unit spike trains recorded from the FDI muscle. The vertical dotted lines from left to right represent the cut-off frequencies of the 0.75 high-pass filter, and the 800 ms, 400 ms and 200 ms moving average low-pass filters. The peak coherence occurs at 1.5 Hz.
