LA segments have both local and global dynamics. A Example temporal coherence matrix between 12 channels arranged by depth for one animal (green = low coherence, yellow = high coherence). Temporal coherence reported as the average proportion of time spent in the low amplitude state during which both channels are synchronously in a low amplitude state (see Methods). B Relationship between the temporal coherence of LA segments in pairs of channels and the distance between those channels along the laminar probe for both original and surrogate channels. N = 7. Mean ± SEM. Least-squares regression lines and significant Pearson correlation coefficients shown. There were insufficient data points to include the maximum interchannel distance (11)
