Fig. 6: Intact lateral line enabled a greater proportion of fish to perform rheotaxis within the first 15 seconds of stimulus onset.

Time series of the proportion of individual fish within each group that performed rheotaxis during flow presentation. A greater proportion of lateral line intact fish (gray = control, n = 248 fish) performed rheotaxis than lesioned fish (blue = CuSO4, n = 204 fish; green = neomycin, n = 222 fish; 18 experimental sessions). The data for all treatments converges after 17 s of flow presentation.
