VPA rats exhibited spatial learning and memory impairment in Morris water maze test. (A) Representative swimming paths of control (left) and VPA-treated (right) rats during the probe trial session in the Morris water maze test. (B) VPA-treated rats had significantly longer escape latency to find the platform than that in control rats (**p < 0.01). (C) VPA-treated rats exhibited slower swimming speed than control rats in the place navigation test (**p < 0.01). (D) Swimming path map of control (left) and VPA-treated (right) crossing different quadrants after removing the platform in the Morris water maze test. (E) VPA rats displayed a reduced number of platform passing (**p < 0.01). (F) VPA-treated rats exhibited less time in target quadrant compared with control rats (**p < 0.01).
