Scatterplot showing relationship between retinal and collicular FGF-2 levels. Symbols represent individual retina versus the corresponding superior colliculus. Significant positive correlations were indicated between retinal and collicular FGF-2 levels for both young D2G (3–5 months) and young DBA/2J (3–5 months) mice (Pearson’s r ²). Regression lines have been drawn for each of these groups to illustrate these relationships. No significant relationships were shown for other groups, including aged D2G mice. p values are indicated on the figure
