Figure 6. Morris water maze. (A, B) The spatial learning and memory test began on postoperative day 8; the graphs indicate the latency and distance for both groups during the 5-d training period. (C) Swimming speed differed between the DCLN model group and SHAM group (P<0.05). (D–F) Time in the correct quadrant, number of transits across the former platform location, and swimming speed in the two groups in the memory probe test on postoperative day 13. Significant differences were found between the DCLN model group and the SHAM group. Significance level: *P<0.05.
