Comparison of relative c-Fos mRNA levels in LCR.

<p>Panel A represents brain areas where there is no statistical difference in mRNA expression between LCR at different time points (LCR at exhaustion = LCR at 7.5 minutes). Panel B represents brain areas where c-Fos mRNA is statistically higher in LCR run to exhaustion versus LCR after 7.5 minutes of running (LCR_exh>LCR_7.5). Panel C represents brain areas where c-Fos mRNA is statistically lower in LCR run to exhaustion versus LCR after 7.5 minutes of running (LCR_exh7.5). N = 8 animals/group. Fisher protected least significant difference: * p<.05 with respect to LCR run 7.5 minutes; ## p<.01 with respect with LCR run to exhaustion.
