Cumulative distance to the target platform during visible and hidden training sessions. (a) During the visible platform training (day 1 and 2), all experimental groups swam similar distances to the platform. All groups showed daily improvements in their abilities to locate during the hidden platform training (day 3–5). However, trauma only (*p < 0.05; day 4, Holms) swam longer escape distances compared to sham mice. (b) All groups showed daily improvements in their abilities to locate during the hidden platform training (day 3–5). Radiation only (*p < 0.05; day 3–5, Holms) swam shorter escape distances compared to sham mice. Each datum point represents the mean of 8–10 mice; error bars are standard error of the mean (SEM).
