Figure 3. Effect of CE administration on inhibitory memory consolidation in the passive avoidance task. FA administration significantly affected the step-through latency (A) and time spent in the dark chamber (B). Although co-treatment of CE at the dose of 200 mg/kg relatively improved the step-through latency and time spent in the dark chamber, the changes were not statistically significant.
