Mean (± standard error of the mean) time (sec) to locate either a hidden or visible platform in a water maze. For hidden platform, *p < 0.05 vs. traumatic brain injury (TBI) + STD + VEH and **p < 0.05 vs. all TBI groups. For visible platform, **p < 0.05 vs. all TBI groups. No other comparisons were significant (p > 0.05). STD, standard; VEH, vehicle; GAL, galantamine.
