Figure 6. Retinal function measured by electroretinography (ERG) in rats fed for eight weeks and maintained under cyclic dim or bright light. A: Scotopic ERG-A and B wave amplitudes of rats fed for eight weeks and maintained in cyclic dim light (DL, 50 lux; n=12; one-way ANOVA). B: Scotopic ERG-A and B wave amplitudes of rats fed for eight weeks and maintained in cyclic bright light (BL, 200 lux; n=12; one-way ANOVA). CONT+DL: Rats fed with control diet and maintained under cyclic dim (50 lux) light for eight weeks; CAPE+DL: Rats fed with CAPE diet and maintained under cyclic dim (50 lux) light for eight weeks; CONT+BL: Rats fed with control diet and maintained under cyclic bright (200 lux) light for eight weeks; CAPE+BL: Rats fed with CAPE diet and maintained under cyclic bright (200 lux) light for eight weeks. (n=12; *: p<0.01, **: p<0.001, one-way ANOVA).
