Bar Plot from Scientific Research

Means of the endogenous period, the circadian phase, and the amplitude in both genotypes during development. The total numbers of retinas used were respectively for wild-type mice: P8, n = 10; P11, n = 10; P15, n = 6; P30, n = 8; adult, n = 10 and for Opn4 -/- ::Per2 Luc ; P8, n = 6; P11, n = 6; P15, n = 7; P30, n = 6 and adult, n = 10. Bars represent the mean SEM (ANOVA, ** = p <= 0.01; *** = p <= 0.001)
