When looking at the intensity of FJC staining relative to DAPI staining, there was a general increase with age across all brain regions ( Figures 8E – H ), with a statistically significant positive correlation with age in the frontal ( Figure 8E ; p = 0.0030) and parietal ( Figure 8G ; p = 0.0481) lobes and a trend toward significance in the cerebellum ( Figure 8H ; p = 0.0720).
