Cross-correlation between MUAP trains and raw EMG. A: Cross-correlations between EMG and sequentially added MUAP trains using original firings from small to large MU indices are shown in circles. Cross-correlations calculated using original firings from large to small MU indices are shown in squares. Cross-correlations calculated using noisy firings (SD of noise = 0.1 * SD of ISIs) are shown in triangles. Cross-correlations calculated using shuffled STA templates are shown in crosses. B: Cross-correlation results of a second subject. The symbol notations are the same as in subject 1. C: Cross-correlations when the first 5 MUAPTs were added together and when all MUAPTs were added. Error bars represent the standard errors across all the subjects.
