Effect of impactor tip shape on neurological motor and cognitive function of mice subjected to cortical impact injury. Mice injured with a flat-tip impactor or a rounded-tip impactor exhibited equivalent motor deficits over the first week after injury, when measured using (A) a 14-point modified neurological severity score (NSS) or (B) a 12-point composite neuroscore. (C) Impactor tip shape also had no significant effect on the ability to learn the location of a hidden platform in a MWM over a 3-day testing period. Dark gray bars or square symbols denote flat-tip impactor group means; light grey bars or diamond symbols denote round-tip impactor group means. Error bars represent standard deviations.
