ipRGCs of younger mice recover more quickly following a short light exposure than ipRGCs or older mice. a Rasters and average histograms of representative ipRGCs used in time course experiments b Time courses of P8 (n = 74), P15 (n = 10 to 15), and P30 (n = 6 to 16) ipRGC recovery following a 1-min light exposure. *: p < 0.05, +: p < 0.005, °: ns. For each time point, first significance symbol is for P8-P15 comparisons and second symbol is for P8-P30 comparisons. LMM, followed by one-way ANOVA and Bonferroni post-hoc for each time point
