Attenuated phase shifting response to light in MW-coneless mice, a) Representative actograms of locomotor activity of WT and MW-coneless (TRβ−/−) mice exposed to 15-min pulses of monochromatic light (370, 480 and 530 nm) at 4 different irradiances and at CT16 (white circle), b) Mean ± SEM (n=8 for each genotype) phase shifts for WT and TRβ−/− mice at the 3 wavelengths tested. A statistically significant difference was observed between the genotypes only for monochromatic stimulation at 530 nm. Control animals handled in the same way but that did not receive a light pulse show no significant difference between genotypes. Asterisks indicates a statistically significant difference between the two genotypes (ANOVA: p<0.05; post-hoc Student Newman-Keuls tests comparing genotypes at each irradiance: *:p<0.05; **:p<0.01).
