FIG. 1.

Graph depicting IGF-1 mRNA in the 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 IGF-1 mRNA. CCII IGF-1 mRNA increased relative to both sham and CCIcon at PID 1, 2, 3, and 7, and relative to sham at PID 14. Results are presented as percentages of sham mRNA ± standard error of the mean; n = 6; *p < 0.05 relative to sham animals; &p < 0.05 relative to CCI con animals; IGF-1, insulin-like growth factor-1; CCI, controlled cortical impact).
