Figure 5. The optokinetic response is normal in both cdh23^tc317e and cdh23^tj264a mutants. Graphs show the averaged slow-phase velocity of both eyes measured under varying contrast (A) and spatial frequency (B) of the optokinetic stimulation. No significant difference was found between any of the groups (repeated measures ANOVA; contrast: F_3,32=0.525, p=0.668; spatial frequency: F_3,32=0.549, p=0.653; n=9 larvae per group).
