A. Sedation with isoflurane increases nonlinear variability. The NLcI quantifies the difference in SampEn between the original and surrogate data, thereby representing a measure of the nonlinear variability contained in the data. The asterisk denotes that the sedation value was significantly different from both the baseline and recovery results. Figure 5B. Sedation with ketamine increases nonlinear variability.
