Fig. 2. Propofol impaired memory for the reactivated story when tested after 24 hours (group A) but not when tested immediately after recovery from anesthesia (group B).

(A) Recognition memory scores for all slides of the reactivated and nonreactivated story (except the first slide) are plotted for each group. Scores (percentage) for each story per group: group A (n = 25 participants) reactivated mean (SEM) = 53.49 (2.29); nonreactivated mean = 59.20 (2.60); group B (n = 24 participants) reactivated mean = 59.52 (1.97); nonreactivated mean = 61.19 (2.11). (B) Percent correct recognition memory scores are plotted for the three story phases of the reactivated (R; solid line) and nonreactivated (NR; dashed line) story for each group. There is a significant impairment of memory for the emotional phase of the reactivated story (phase 2) in group A only. Chance recognition performance (25%) is indicated by the dotted horizontal line. *P < 0.05.
