Mean time (sec) (±standard error of the mean) to locate a hidden (submerged) platform in the Morris water maze (*p<0.0024 versus all other TBI groups; **p<0.0001 versus all TBI groups). In addition, aside from the TBI + BUS (0.5 mg/kg) group performing significantly worse than the TBI + BUS (0.01 mg/kg) group (p=0.0014), no other group comparisons were significant (TBI, traumatic brain injury; BUS, buspirone; VEH, vehicle).
