Neurocognitive behavior at PND 50.

<p><b>A</b> shows the average latencies, the time required for each animal to reach the hidden platform, of the four trials for the initial 5 days. <b>B</b> shows the area under curve (AUC) derived from <b>A</b>. <b>C</b> shows the percentage of the time the rats spent in the platform area in the probe trial on the 6^th testing day. Control group have significant neurocognitive impairment when compared to naïve group. There is no difference between sevoflurane, xenon groups and naïve group. <b>D</b> shows there is no difference in the average velocity in each group. Data are expressed as mean ± SEM (n = 5–6) and compared by one-way analysis of variance and Student-Newman-Keuls method. * p<0.05, **p<0.01.
