Figure Caption

Fig. 7 bum^-/- zebrafish are severely visually impaired. (A–B) Lateral (A) and dorsal (B) views of adult bum^-/- mutant zebrafish and sibling (wild-type) zebrafish swimming together. Note the significantly darker overall appearance of the mutant fish (asterisks; lower individual in A and upper individual in B, respectively) compared to their siblings when kept under bright light conditions. (C–F) Optokinetic response of bum^-/- mutants and siblings at 5 dpf (C, D) and 7 dpf (E, F). Both contrast sensitivity (C, E) and visual acuity (D, F) are affected by the mutation. In both paradigms the eye velocity as a measure of visual performance is lower in bum^-/- mutant larvae compared to their siblings. The inset in C shows a schematic representation of the experimental set-up.
