Fig. 2. Pupil size and EEG. Time traces of pupil size and parietal EEG activation in (A) deep anesthesia (2% isoflurane) and (B) light anesthesia (0.5%) in emergence phase. The quickly widening dilation of pupil exemplified in (B) was counted as mydriasis. The spectrograms of the corresponding EEG traces were shown accordingly.
