myo7aa−/− larvae exhibit larger turning angles. Movement tracking of 5 dpf wild-type and myo7aa−/− larvae at 2.5-min intervals, with 5 ms electric stimuli (50 mV) administered every 20 s. Ctrax software was used for video processing and MATLAB 2012b for video analysis. (A,B) myo7aa−/− larvae have larger absolute smooth orientations (global change in body orientation) compared to wild-type larvae. Individual turning angles from a population of wild-type and myo7aa−/− larvae were used to construct the lines (two-tailed t-test). Bold black lines in B represent the mean of the data set and error bars are 95% confidence intervals. Experiments were replicated five times for both wild-type and myo7aa−/− mutants.
