A. Isoflurane increases statistical dependence as measured by Mutual Information for original data but not surrogate. While the Mutual Information increased for the original data set during sedation, the same was not true for the surrogate data set. The asterisk denotes where the value during sedation is significantly different from both the baseline and recovery values. Figure 3B. Ketamine increases statistical dependence as measured by mutual information for both original and surrogate data.
