Thus, visible differences in cross-correlation are highly statistically significant. Figure 3b Results shown are derived as for figure 3a except that uncorrelated white noise was delivered to all parts of each bar, as well as being uncorrelated between bars. Diffuse field noise amplitude 0.000025. Figure 3c Cross-correlations for the asynchronous bar case, with diffuse field noise 0.000025, for bars moving in the same and opposite directions. See text for details.
Differences are between the remote and proximate conditions.
The small differences remain statistically significant. Differences are with respect to the directions of bar movement shown in the graphs to the left of each difference graph. The difference produced by direction of movement is zero at zero lag in the absence of diffuse field noise.

Average power spectra and pulse-cross correlations calculated as for the two short bars moving in the same direction case, in figure 3a.
