Figure 2. Detection of spatial learning and memory by Morris water maze.
A) Escape latency time by Morris water maze tested from 3 weeks after 2VO surgery. B) Percentage of time spent in the target (memory retention ability) at 4 weeks after 2VO surgery. C) Escape latency time by Morris water maze tested from 5 weeks after 2VO surgery. D) Percentage of time spent (memory retention ability) in the target at 6 weeks. * P<0.05. ** P<0.01. N=13/group.
