Figure 6. Task-dependent changes in oscillatory and non-oscillatory synchrony: single subject.

Figure 6

A shows the performance of the subject. The yellow line indicates the position of the yellow target boxes and the red line indicates the subject's average performance over all correctly performed trials. B shows the unseparated rectified EMGs for 1DI and AbPB averaged over all correctly performed trials. The EMG traces shown were down-sampled to an effective sampling rate of 100 Hz and low-pass filtered at 10 Hz. C-E, time-lag maps showing variation in cross-correlation during performance of the task, calculated between separated AbPB and 1DI EMGs for a single subject, across 50 trials. The ramp phase of the task occurred at time 3–5 s. A shows the time-lag maps for the raw data and B for the raw data notch filtered to exclude data in the 15–30 Hz range. C shows the time-lag map produced by the subtraction of the filtered from the raw map. F-H shows the modulation in the amplitude of the central peak with respect to the time.
