Figure 3

Oddball and heel-strike locked WPLI deflections for the same subject as in Figure2 plotted over epochs from 0.5 s before to 1 s after the time-locking event. The color mapped WPLI response of all (a, d), clean (b, e), and bad(c, f) channel pairs (62 k = 61,504) during standing (top row) and walking (bottom row) are shown. Only data from the first 25% of each session was used. Channel pair WPLI measures are sorted and numbered by their correlation to the mean WPLI response. There is a clear and uniform WPLI deflection across almost all channels. This deflection can be seen even when both channels are considered bad and for the walking case. Panel (i) shows the WPLI deflections time-locked to left heel-strikes.
