Compared to middle-aged ad libitum fed male mice ( Supplementary Figure 2 ), CR3 induced a significant reduction in the frequency of spontaneous Ca 2 + transients ( p < 0.01, Mann-Whitney test) and an almost significant reduction in T-half ( p = 0.05, Mann-Whitney test), thus counteracting all aging-related changes observed in this age group (compare to Figure 3 ).
