**Figure 3.** **Differential circRNA expression in the cerebellum with aging.** (**A**) Bar plot representation of differentially expressed circRNAs in different age groups. (**B**–**G**) Volcano plots showing the dysregulated circRNAs in the cerebellum in different age groups. The log of FC (base 2) is plotted on the x-axis and the negative log of FDR (base 10) is plotted on the y-axis (FC >2 and *p* < 0.05). The green and red points on the graph represent downregulated and upregulated circRNAs, respectively.
