The effects of chronic visual impairment on fly locomotor activity. (A) Travel distance of flies within 10-min period was measured. No significant difference in locomotion was observed between ninaB¹ and wild-type flies or between ninaB¹ and rescued flies. Pairs of flies tested: CS, n = 30; ninaB¹ Rescue, n = 22; ninaB¹, n = 30. (B) Travel distance of eya² homozygous mutant flies was measured. Compared to that of wild-type or eya² heterozygous flies, lower locomotor activity was observed in eya² homozygous mutant flies. Pairs of flies tested: CS, n = 30; eya²/+, n = 29; eya², n = 26. ^**p < 0.01, ^***p < 0.001. Error bars represent SEM.
