FIG. 3.

Effects of injury on visible platform phase of the Morris water maze. (A) Average swimming speeds for each day of the visible phase of the Morris water maze during each of the three test sessions. There was a significant effect of injury on swim speed (0.24J vs. sham: p = 0.000127, 20 × concussive vs. 20 × subconcussive; p = 0.000128). There was no interaction between test session and injury. (B) Total distance to the target platform during 3 days of visible platform testing. There was a significant effect of repetitive concussive injury (20 × concussive vs. sham: p = 0.000127, 20 × concussive vs. 20 × subconcussive: p = 0.000127). Color image is available online.
