GFAP expression in SCN. Digital image of coronal section showing GFAP expression in adult SCN (a) and aged (b). Relative optical density measured showed a significant increase of GFAP expression in aged SCN compared to adult marmoset (c). Besides, Spearman test pointed to a significant positive correlation between GFAP-IR and age. Significant correlations (Spearman correlation—) when *. ctr: control area. Scale bar: 50 μm.
