Bar Plot from Scientific Research

Mean light-induced phase shift after a 465 nm light stimulation at CT16 (30 min, 10 14 photons/cm 2 /s) in wild-type and Opn4 -/- :: Per2 luc retinas with or without MMA supplementation (MMA). Bars represent mean +/- SEM (C: n = 4 for both genotypes; MMA, n = 4). Statistical differences with the C are indicated by **: p <= 0.01; ***: p <= 0.001
