Figure 6

Pair-wise correlation of high-intensity firing (HI) periods from all units as a function of anesthetic state. Data are shown separately for two groups of rats; those that experienced local field potential (LFP) burst suppression at 8% desflurane and those that did not. (A) Correlation among units recorded from neighboring electrode sites (data from Figure 5). (B) Correlation among units recorded at the same electrode shank. (C) Correlation among units recorded from electrode sites at the same cortical depth. In each case, correlation showed significant linear trend at between 6% and 0% desflurane. The correlation coefficients at 8% desflurane were significantly different between the two groups, suggesting hypersynchrony in the presence of burst suppression. *: p<0.001, linear trend across 8%–0% desflurane in the non-bursting group. #: p<0.05 vs. other group at 8% desflurane.
