FIG. 3.

Hippocampal brain-derived neurotrophic factor (BDNF) levels in control and fluid percussion injured (FPI) rats at post-injury day (PID) 11 after forced (fRW) or voluntary (vRW) exercise. Each histogram represents the mean±standard error of the mean for 6–16 samples per condition. (A) Total BDNF as detected by an enzyme-linked immunosorbent assay expressed as pg/mg protein (*p<0.05 versus the control-SED and control-fRW groups). (B) Mature BDNF (mBDNF) detected with Western blot, expressed as percent increase over control-SED content (SED, sedentary).
