Fig. 6 Long wavelengths modulate search behavior in blind larvae. (A, B) Representative image of 6 dpf sibling (+ /?) and homozygous atoh7 mutant (–/–). Below are illustrative path trajectories following the loss of light for each tested condition. C-N) Quantification of motor metrics for siblings (left) and mutants (right). Showing distance (C–F), TTA (G–J), and fractal dimension (K–N). Asterisks in bar graphs indicate p ≤ 0.05 to white light controls during that period (base or dark). For fold change line graphs asterisk shows p ≤ 0.05 to white light control where effected wavelength is indicated, and arrow shows direction of change. N’s: sibling cold white light = 142, 415 nm = 56, 530 nm = 50, 660 nm = 57; atoh7 white light = 114, 415 nm = 48, 530 nm = 36, 660 nm = 50.
