Graph depicting bax mRNA in CCI hippocampus ipsilateral to injury (CCII) obtained at post-injury days (PID) 1, 2, 3, 7, and 14, presented as a percentage of corresponding sham mRNA levels. The dashed line represents 100% of sham bax mRNA. CCII bax mRNA was increased at PID 2 and at PID 14. Results are presented as percentage of sham mRNA ± standard error of the mean; n = 6; *p < 0.05 relative to sham animals; CCI, controlled cortical impact).
