Figure 6

Pooled autospectra, phase, coherence and cumulant calculated from records of APL and APB rectified EMGs recorded from the dominant hand of 11 adult subjects aged 22–59 years. A, pooled autospectra from APL. B, pooled autospectra from APB. C, plot of proportion of records (n= 11) that showed significant (P < 0.05) coherence at frequencies between 1 and 90 Hz. D, pooled phase for frequencies between 1 and 90 Hz. E, pooled coherence (n= 11) between 1 and 90 Hz. The coherence is significant between 1 and 38 Hz, with maxima at 1, 12 and 22 Hz. F, pooled cumulant density plotted ±250 ms; the cumulant contains a central peak magnitude q(u) = 0.05. Confidence limits for coherence and cumulant density estimates as in Fig. 2.
